Definitions
- the present invention relates to an apparatus and a method for recovering heat generated during the incineration of combustible wastes, such as city garbage containing incombustible matters, waste plastics and industrial wastes, in a fluid-bed type incinerator, and a method for inhibiting resynthesis of detrimental dioxins occurring in a combustion waste gas discharged from the incinerator.
- combustible wastes such as city garbage containing incombustible matters, waste plastics and industrial wastes
- a fluid layer of sand particles and the like as a fluid medium is formed in a lower portion of the incinerator.
- Combustible wastes charged into the incinerator are burnt while being fluidized together with the sand particles which have been previously heated to a prescribed temperature, in the fluid layer.
- An air chamber is provided on a bottom of the fluid-bed type incinerator. Air blown into the air chamber from a blower is ejected upward from the air chamber into the incinerator through an air dispersing plate such as a porous plate, and the thus ejected air fluidizes the fluid medium such as sand particles, thereby forming the fluid layer. In the fluid layer, the fluid medium moves up and down to form a fluidized state.
- a combustion waste gas produced from the combustion of the wastes is, on the other hand, introduced through a flue into a dust collector, in which dust contained in the combustion waste gas is collected.
- combustible wastes such as city garbage and industrial wastes are charged through a waste charging port (not shown) provided on the upper portion of a fluid-bed type incinerator 1 into a fluid layer 2 kept at substantially a uniform temperature.
- the charged wastes are burnt while being fluidized together with the sand particles as a fluid medium, in the fluid layer 2.
- Incombustible matters contained in the wastes to be incinerated are transferred outside the incinerator through an incombustible matter discharge port (not shown) provided on the bottom of the incinerator 1.
- Slant partitions 5 are provided above an upper portion of an air chamber 4 positioned near an incinerator side wall, of the air chamber 4 partitioned into a plurality of cells. Under the effect of the slant partitions 5, air for fluidizing the fluid medium is reflected toward the center of the incinerator 1. As a result, a rotary flow 3 is produced in the fluid layer of the fluid medium as shown by a large arrow in Fig. 5.
- a heat recovering chamber 6 partitioned by them is formed, and plurality of heat transfer tubes 7 are inserted horizontally from the incinerator side wall toward the slant partition 5.
- a part of the fluid medium forming the fluid layer 2 passes over the slant partition 5 and enters the heat recovering chamber 6.
- heat of the fluid medium is recovered by means of the heat transfer tubes 7.
- the fluid medium after being recovered heat, circulates again to the center portion of the incinerator 1 and is incorporated into the rotary flow 3.
- a plurality of straight heat transfer tubes 7 are substantially vertically arranged in a heat recovering chamber 6 of a fluid-bed type incinerator 1 along a side wall thereof.
- An upper portion and a lower portion of each of the plurality of heat transfer tubes 7 are connected to an upper water chamber 9 and a lower water chamber 10, respectively.
- the upper water chamber 9, the heat transfer tubes 7 and the lower water chamber 10 communicate with each other.
- the prior art 2 discloses a heat recovering apparatus in which a plurality of heat transfer tubes are inserted horizontally from the incinerator side wall horizontally into the incinerator, as in the apparatus of the prior art 1 shown in Fig. 5.
- a combustion waste gas produced during the combustion of wastes is introduced through a flue into a dust collector, and after the collection of dust and the like, diffused to the open air.
- the combustion waste gas produced during the combustion of wastes in the incinerator contains dioxins having a strong toxicity though in a slight amount, which include polychlorinated dibenzo-p-dioxin and polychlorinated dibenzofuran. Inhibition of the production of these dioxins is now an important problem.
- Japanese Patent Publication No. JP-B-61-24,606 discloses a method for removing hydrogen chloride contained in a combustion waste gas discharged from an incinerator, which comprises the step of: when forming a fluid layer comprising inert particles in an incinerator to burn wastes in said fluid layer, adding granular dolomite containing particles having a particle size of from about 2 to 5 mm in an amount of at least about 80 wt.% into the incinerator, thereby removing hydrogen chloride in a combustion waste gas (hereinafter referred to as the "prior art 5").
- the prior art 5 discloses a method for removing hydrogen chloride in a combustion waste gas by adding granular dolomite containing particles having a particles size of from about 2 to 5 mm, but discloses nothing about inhibition of production of dioxins.
- An object of the present invention is therefore to overcome the problems in the above-mentioned prior arts and to provide an apparatus and a method for recovering heat generated in a fluid-bed type incinerator during the incineration of combustible wastes such as industrial wastes in the incinerator, which apparatus and method permit the performance of replacement operation of a plurality of heat transfer tubes safely in a short period of time without causing incombustible matters in the wastes to cling to the heat transfer tubes, as well as a method for inhibiting the production of dioxins, which enables to inhibit the resynthesis of dioxins in a flue running from the incinerator to the dust collector, while a combustion waste gas discharged from a combustion waste gas discharge port of the incinerator, is introduced through the flue into the dust collector for collecting dust.
- a method for recovering heat from an incinerator which comprises the steps of:
- an apparatus for recovering heat from an incinerator in which a plurality of heat transfer tubes are arranged in a peripheral portion of a fluid layer of a fluid-bed type incinerator, and heat generated from combustion of an object to be incinerated in said fluid layer is recovered via a heat receiving medium flowing through said plurality of heat transfer tubes; characterized in that:
- said plurality of heat transfer tubes comprise unit heat transfer tubes.
- a method for recovering heat from an incinerator and inhibiting production of dioxins which comprises the steps of:
- each of the heat transfer tubes in contact with the fluid layer containing incombustible matters does not have a horizontal portion except for the bent tube portion forming the lower portion of the heat transfer tube, the moving direction of a fluid medium moving only up and down agrees with the axial direction of the heat transfer tube, thus permitting prevention of incombustible matters from clinging to the heat transfer tubes.
- the present invention was made on the basis of the foregoing findings, and the method of the present invention for recovering heat from an incinerator comprises the steps of:
- the apparatus of the present invention for recovering heat from an incinerator, in which a plurality of heat transfer tubes are arranged in a peripheral portion of a fluid layer of a fluid-bed type incinerator, and heat generated from combustion of an object to be incinerated in said fluid layer is recovered via a heat receiving medium flowing through said plurality of heat transfer tubes, is characterized in that:
- said plurality of heat transfer tubes comprise unit heat transfer tubes.
- the method of the present invention for recovering heat from an incinerator and inhibiting production of dioxins comprises the steps of:
- each of the plurality of heat transfer tubes comprises a U-shaped heat transfer tube which has two vertical tube portions, and a bent tube portion having both ends thereof communicating with the respective vertical tube portions, and the plurality of heat transfer tubes are removably arranged in the vertical direction in the incinerator from a wall thereof.
- the plurality of heat transfer tubes may comprise unit heat transfer tubes.
- a heat receiving medium flows downward from above an upper incinerator wall in one of the vertical tube portions, and after reaching the bent tube portion located in a fluid layer of the incinerator, flows upward in the other of the vertical tube portions.
- the heat receiving medium then flows out to above the upper incinerator wall.
- the heat receiving medium can therefore efficiently recover heat of the high-temperature fluid layer.
- each of the heat transfer tubes in contact with the fluid layer containing incombustible matters does not have a horizontal portion except for the bent tube portion forming the lower portion of the heat transfer tube, the moving direction of the fluid medium moving only up and down agrees with the axial direction of the heat transfer tube.
- the incombustible matters never cling to the heat transfer tubes, thus permitting smooth recovery of heat from the fluid layer while keeping the fluid layer in a satisfactory state. Further, there is present a very short horizontal portion in the bent tube portion of the heat transfer tube. However, because the gap between the downward vertical tube portion and the upward vertical tube portion is very small, the bent tube portion of the heat transfer tube is almost free from clogging of incombustible matters.
- connecting portions of the plurality of heat transfer tubes provided on the incinerator wall are above the fluid layer (i.e., in the present invention, the heat transfer tubes are vertically attached and removed from the incinerator wall located above the fluid layer), it is not necessary to remove the fluid medium from the incinerator upon replacing the heat transfer tubes, thus permitting replacement of the heat transfer tubes in a short period of time. Even when the heat transfer tubes are removed from the incinerator wall, the replacing operation of the heat transfer tubes can be safely carried out without splash of the high-temperature fluid medium to outside the incinerator, because the connecting portions of the heat transfer tubes are located above the fluid layer as described above.
- the heat transfer tubes can be more efficiently replaced.
- the production of dioxins in the incinerator is inhibited by appropriately adjusting the combustion conditions, i.e., the combustion temperature, the gas staying time and the gas turbulence condition, as set forth in the Guideline established by the Ministry of Health and Welfare.
- a calcium compound such as limestone (CaCO 3 ) and slaked lime (Ca(OH) 2 ) having a particle size of up to 500 ⁇ m is supplied into the incinerator.
- the supplied calcium compound having a particle size of up to 500 ⁇ m is introduced into a flue from the incinerator together with a combustion waste gas, and convert hydrogen chloride (HCl) present in the combustion waste gas flowing through the flue and causing the production of dioxins, into innoxious calcium chloride (CaCl 2 ) through a reaction expressed by the following formulae: CaCO 3 ⁇ CaO + CO 2 Ca(OH) 2 ⁇ CaO + H 2 O CaO + 2HCl ⁇ CaCl 2 + H 2 O
- the innoxious calcium chloride (CaCl 2 ) produced from the foregoing reaction is collected in a dust collector and removed. During the time in which the combustion waste gas discharged from the incinerator passes through the flue and reaches the dust collector, therefore, resynthesis of dioxins is certainly inhibited.
- the particle size of the calcium compound to be supplied into the incinerator should therefore be up to 500 ⁇ m. From the point of view of manufacture or handling, the particle size of the calcium compound should preferably be at least 100 ⁇ m.
- the amount of supplied calcium compound should preferably be at least 2 in a molar ratio of Ca/(1/2 Cl).
- sulfur (S) is contained in the wastes to be incinerated, the amount of supplied calcium compound should preferably be at least 2 in a molar ratio of Ca/(1/2 Cl + S) , taking account of the amount of the calcium compound to be consumed in a reaction between sulfur and the calcium compound as represented by the following formula: CaO + SO 2 - CaSO 4
- the molar ratio of Ca/(1/2 Cl) or Ca/(1/2 Cl + S) should therefore preferably be up to 10.
- the calcium compound may previously be mixed in the wastes to be incinerated to supply same together with the wastes into the incinerator, or may be supplied separately from the wastes into the incinerator.
- Fig. 1 is a schematic sectional view illustrating a first embodiment of the apparatus of the present invention for recovering heat from a fluid-bed type incinerator.
- a fluid-bed type incinerator 11 equipped with the apparatus of the first embodiment for recovering heat, the incineration of wastes, the recovery of heat and the replacement of a plurality of heat transfer tubes were carried out.
- a horizontal incinerator wall 13 having holes (not shown) is formed on the incinerator wall surrounding a free board section 12 of the fluid-bed type incinerator 11, and a plurality of U-shaped heat transfer tubes 14 are vertically inserted into the incinerator 11 through the holes piercing the horizontal incinerator wall 13.
- the plurality of heat transfer tubes 14 are inserted into the incinerator 11 so that a bent tube portion 20 of each heat transfer tube 14 is immersed in a fluid layer 15 to be formed by a fluid medium such as sand particles.
- Each heat transfer tube 14 comprises two horizontal tube portions 18 connected respectively to an entry header 16 and an exit header 17, two vertical tube portions 19 extending vertically from the respective horizontal tube portions 18, and a U-shaped bent tube portion 20 having both ends thereof communicating with the respective vertical tube portions 19.
- each heat transfer tube 14 flows, as shown by an arrow in Fig. 1, from the entry header 16 through one of the horizontal tube portions 18 outside the incinerator 11 into one of the vertical tube portions 19 in the incinerator 11, flows downward through the one of the vertical tube portions 19, flows upward through the other of the vertical tube portions 19 via the lowermost bent tube portion 20, and flows out into the exit header 17 through the other of the horizontal tube portions 18.
- 21 is an air dispersing plate
- 22 is an air chamber partitioned into a plurality of cells
- 23 is an incombustible matter discharge port.
- Sand particles serving as the fluid medium are fluidized by means of air ejected from the air chamber 22 through the air dispersing plate 21 provided on the bottom of the incinerator 11 to form the fluid layer 15.
- Combustible wastes such as city garbage, waste plastics and industrial wastes are charged into the thus formed fluid layer 15 to incinerate the wastes.
- the plurality of heat transfer tubes 14 are vertically inserted into the incinerator 11 from the horizontal incinerator wall 13 above the fluid layer 15 as described above. Steam serving as the heat receiving medium first flows downward toward the lowermost portion of each heat transfer tube from the horizontal incinerator wall 13, and after reaching the lowermost bent tube portion 20, flows again upward to flow out from the horizontal incinerator wall 13.
- the plurality of heat transfer tubes 14 are immersed vertically into the fluid layer 15. Motion of the sand particles as the fluid medium moving up and down is therefore never prevented. As a result, a satisfactory fluidized state of the fluid layer 15 could be maintained. Further, incombustible matters in the fluid layer 15 never clinged to the heat transfer tubes 14.
- Replacement of the plurality of heat transfer tubes 14 could easily be accomplished, by releasing the joint between the horizontal incinerator wall 13 of the incinerator 11 and the heat transfer tubes 14, pulling out the heat transfer tubes 14 upward from the incinerator 11, and inserting new heat transfer tubes into the incinerator 11.
- heat could efficiently recovered from the fluid layer 15 of the incinerator 11. Further, upon replacing the plurality of heat transfer tubes 14, it was not necessary to discharge the sand particles as the fluid medium to outside the incinerator 11. Even after the completion of the replacing operation of the heat transfer tubes 14, therefore, the fluid layer 15 kept a sufficient temperature necessary for burning combustible wastes. As a result, after the completion of the replacing operation of the heat transfer tubes 14, the operation of the incinerator 11 could immediately be restarted.
- Fig. 2 is a schematic sectional view illustrating a second embodiment of the apparatus of the present invention for recovering heat from a fluid-bed type incinerator.
- a fluid-bed type incinerator 11 equipped with the apparatus of the second embodiment for recovering heat, the incineration of wastes, the recovery of heat and the replacement of the plurality of heat transfer tubes were carried out.
- unit heat transfer tubes 25 are used .
- the unit heat transfer tubes 25 comprise a connector 24, of which the interior is partitioned into prescribed shapes, and a plurality of U-shaped heat transfer tubes 14, of which the both ends communicate with the connector 24.
- the plurality of heat transfer tubes 14 are integrated into one by means of the connector 24.
- Fig. 2 12 is a free board section; 21 is an air dispersing plate; 22 is an air chamber partitioned into a plurality of cells, and 23 is an incombustible matter discharge port.
- the number of the heat transfer tubes 14 in the unit heat transfer tubes 25 is determined within a range of from two to several hundred in an incinerator having a capacity within a range of from 24 to 300 tons/day, in response to a heat quantity to be recovered from the fluid layer 15 of the incinerator 11, and a position for insertion of the unit heat transfer tubes 25.
- heat could efficiently be recovered from the fluid layer 15 of the incinerator 11. Further, upon replacing the unit heat transfer tubes 25, it was not necessary to discharge the sand particles serving as the fluid medium to outside the incinerator 11. As a result, even after the completion of the replacing operation of the unit heat transfer tubes 25, the fluid layer 15 kept a sufficient temperature necessary for burning combustible wastes. After the completion of the replacing operation of the unit heat transfer tubes 25, therefore, the incinerator 11 could immediately be restarted.
- Fig. 3 is a schematic sectional view illustrating a third embodiment of the apparatus of the present invention for recovering heat from a fluid-bed type incinerator.
- the apparatus of the third embodiment has substantially the same fundamental structure as that of the apparatus of the second embodiment shown in Fig. 2 except that a slant incinerator wall 26 is adopted in place of the horizontal incinerator wall 13 in the second embodiment.
- a slant incinerator wall 26 is provided above the fluid layer 15 of the incinerator 11, as shown in Fig. 3.
- the reason is as follows: when combustible wastes are burnt in the fluid layer 15 with the lowest possible oxygen concentration for the purpose of controlling the oxidized atmosphere and the reduced atmosphere in the incinerator 11 upon burning wastes in the fluid layer 15, unburnt gases having a high calorific value are produced in a large quantity from the fluid layer 15.
- the inclination angle of the slant incinerator wall 26 can be varied between the horizontal and 45°. With an inclination angle of over 45°, the number of heat transfer tubes 14 capable of being inserted into the fluid layer 15 decreases, so that it becomes difficult to sufficiently recover heat from the fluid layer 15. When it suffices for the quantity of recovered heat to be small, however, the inclination angle may be over 45°.
- unit heat transfer tube 25 are used as in the second embodiment. More specifically, the unit heat transfer tubes 25 comprise a connector 24, of which the interior is partitioned into prescribed shapes, and a plurality of U-shaped heat transfer tubes 14 of which the both ends communicate with the connector 24. That is, in the unit heat transfer tubes 25, the plurality of heat transfer tubes 14 are integrated into one by means of the connector 24.
- Fig. 3 12 is a free board section; 21 is an air dispersing plate; 22 is an air chamber partitioned into a plurality of cells; and 23 is an incombustible matter discharge port.
- Fig. 4 is a conceptural view illustrating a method of the present invention for inhibiting production of dioxins in a fluid-bed type incinerator.
- Silica sand particles serving as a fluid medium are placed on an air dispersing plate 32 provided in a fluid-bed type incinerator 31.
- the silica sand particles are fluidized by means of air blown upward from below the air dispersing plate 32 into the incinerator 31.
- 33 is a waste charger into the incinerator 31
- 34 is a calcium compound supplier into the incinerator 31.
- the wastes charged into the incinerator 31 by the waste charger 33 are stirred, dried and burnt by means of the fluid medium in the fluid layer, which have previously been heated to a prescribed temperature by the use of a heater (not shown).
- the combustion waste gas is discharged from a combustion waste gas discharge port 35 into a flue 36, and flows into a bag filter 37 serving as a dust collector through a waste gas inlet 38.
- the combustion waste gas of which dust has been removed by means of the bag filter 37 is released to the open air from a waste gas outlet 39.
- the concentration of hydrogen chloride in the combustion waste gas at the combustion waste gas discharge port 35 of the incinerator 31 was higher in the example of the invention No. 1, in which limestone as the calcium compound having a particle size of up to 500 ⁇ m within the scope of the present invention was supplied, than in the example for comparison No. 1, in which limestone having a particle size of from 1,000 to 2,000 ⁇ m outside the scope of the present invention was supplied into the incinerator 31.
