[Best form of encouragement to carry out the invention]

In FIG. 1, reference number 2Fi infrared burner unit is shown. The present invention Also used in this unit 2, including the burner plate/block assembly. It will be done.

The burner block assembly 3 directs the combustion gas and air mixture into the distribution block 4. The material is transported to a second block (the next is a radiation block) 5 of a material different from that of the material and distributed. A first block (or distribution block) 4t of material to be used. radiation block 5 completes the conveyance and distribution of the mixture and covers the combustion zone. Therefore, the gas The top surface of the second block 5 is heated by combustion to incandescent heat (in the range of approximately 1100 to 1400℃) Then, it emits highly efficient infrared radiation. The mixture is e.g. the second block 5 by means of a piezoelectric igniter or a pilot flame (not shown). is first ignited adjacent to the top surface of the To compose the burner block assembly 3-containing Means are provided for connecting the first block 4 and the second block 5. Block 4.5 Such means of holding the parts together include molecular bonding, sealing, This includes chemical bonding such as bonding and/or mechanical bonding such as molecular attraction and clamping. There is. For convenience of explanation, chemical bonding is determined by the block material used. , a general type of mechanical connection, namely a clip-on clamp 11, is used.

Various embodiments of the block assembly 2 are shown in FIGS. 2 and 3.4. block collection The union 5 forms the gas-air outlet surface or side of the envelope 8. gas and gas The mixture enters chamber 6 from chamber 8 via tube 7t. sufficient to give the desired mass flow rate. Although a source 8 preferably provides sufficient pressurized gas and air, in certain cases conventional Pentieri inhalers are often used. Air and combustion gases supplied by source 8 The mixture supports complete combustion without the need for auxiliary air.

A special metal screen or mesh 9 is placed at a short distance from the top of the radiating block 5. established in Screen 9 is heated to white heat by combustion of the gas-air mixture This generates radiant heat in addition to the heat generated by the radiant block 5. Ru.

To further reduce flashback, the inlet side to the distribution block 4 is equipped with a number of small holes. is provided with a thin metal screen i or membrane 10 made of oriice. that small hole Its dimensions are small enough to serve as a flame trap during low gas-air flow velocities. There is. However, the screens 9 and 10 may be omitted if necessary.

The length and width of each block aggregate is determined by the use in which the aggregate will be placed. . As a result, only details including cross-sections are shown. As mentioned above, the total thickness of the aggregate The radiation block must be less than about 2.5α, and the radiation block is almost thinner than the distribution block.

In FIG. 2, which shows in more detail a sectional view of an embodiment of the first block assembly 5, , reference numeral 15, consists of a number of small first spaces (not shown) connected together. a first block of material or a portion of distribution block 14 and a portion of material within distribution block 14; A material consisting of a large number of small second space thresholds connected together that are larger than those of the first space. 2 shows a portion of the second block of material or radiation block 15; The dimensions of the first space are A pressurized mixture of combustion gas and air is passed through the small Wc1 space in 1 block 14. When forcing, the flow velocity becomes larger than the flame propagation velocity in the mixture. There is. The dimensions of the second space in the second block 15 are such that the mixture ta flow aggregate expands; The upper surface of the radiation block 15 is shaped so as to be ignited and combusted. heated to very high incandescent temperatures, which generate highly efficient infrared radiation. . The material within each block is reticulated, including a precise, single-distributed pore structure. It may have a body. This small pore structure is made of a porous material as well as the distribution block 14. It may be the shooting block 15. As mentioned above, the thermal expansion and The thermal conductivity must be low, e.g. the thermal conductivity should be low, e.g. The temperature must be low enough (approximately 150°C) to prevent flashback. many kinds Porous ceramic materials provide these properties. Thermal expansion of radiation block 15 must be low, but its heat conduction, heat resistance, and dissipation must be as high as possible. Silicon carbide is such a material. Alternatively, highly emissive materials, e.g. Metal silicates and silica carbides are not oak, but contain cobalt, nickel, chromium, It is also possible to accept pseudo-a of metal oxides such as thorium. The size of these materials The fish may be impregnated into the top layer. The selective screen mentioned in connection with Figure 1 Lean? , 10 can provide advantages. This expands the selection of porous materials. Geru. Based on the reticulated material selected, the radiant block can be either a distribution block or a non-distribution block. Always thinner (e.g. 206 mm compared to 10-20 mm for distribution blocks). this to allow uniform combustion across multiple burner surfaces connected to the same manifold. If the sea urchin is not thick enough to provide back pressure to the gas-air mixture. No. The hole size in block 14 must be small enough to prevent flashback. Must be.

In the fss diagram showing details of another embodiment of the block assembly 3 of the wE1 diagram, see Number 23 indicates the first block (distribution block) consisting of a number of small individual channels 26. Fig. 2 shows a part of a cross-sectional view of a block assembly consisting of block] 24. Each channel It is perpendicular to the radiation plane consisting of the section 27 and the second section 28. The first section 27 is sg2 Since the cross-sectional area of section 28 is smaller than that of section 28, it is possible to pressurize the combustion gas and air. The mixture passing through the first section 27 when the mixture is forced through the first section 27LP The speed of flame propagation through the mixture also increases. The second section 28 is connected together. so as to contact a second (radiating) block 25 of material consisting of a number of interconnected spaces. The cross-sectional area of the second section 28 is a variable cross-sectional area that first starts expanding into a bowl shape until The mixture is poured into the cross-sectional area. Dimensions of space inside second block 25 In the method, the mixture tj is stretched once, the turbulent mixture is formed and ignited once, and then the The top surface of the radiant block 25 is heated to a very high incandescent temperature and the block is heated to a very high temperature. Generate efficient infrared radiation.

Channel materials and designs for distribution block 24 are well known in the art. Ru. The heat conduction and thermal expansion of the distribution block 24 are Lithium silica salt, such as [CordioriteJ, jMulli by various ceramic materials such as those sold under various trademarks such as teJ. It must be as low as 5.

Since distribution and combustion can occur within the second section of the distribution block 24, the A thin radiating block 25 W, similar to that shown in Figure 2, is also used in this embodiment. sell.

The radiation block acts to delay the "pull-up" of the 25σ flame, thereby Allows a wide range of air flow rates/energy inputs. Combustion occurs in the expansion section of the distribution block 24. Whether it occurs within the special section design is not limited to flow velocity, radiation block 25 Depends on thickness and porosity.

In FIG. 4, which shows in detail still another embodiment of the block assembly 5 of FIG. Reference numeral 35 consists of a number of small individual first channels within distribution block 34. A part of the cross section of the block assembly is shown. Each channel 36 is perpendicular to the emission plane, and When the pressurized mixture of combustion gases and air is forced through the distribution block 34i, the The velocity of the mixture through channel 56 is greater than the velocity of flame propagation within the mixture. a large number of second channels having a cross-sectional area and directly aligned with the small first channel 36; 57, at least one second Channel 36 extends until channel 57 meets first channel 56. Second WE2 channel 3 until channel 37 contacts the top surface of second block 36 of material. The cross-sectional area of 7 is a variable cross-sectional area where expansion t-starts first into a bowl shape. radiation block 3 The dimensions and shape of the channels 370 in the mixture t-expand, turbulent mixture The entire upper surface of the radiant block 35 has a very high incandescent temperature. The block 35 generates highly efficient infrared radiation. distribution block The material and design of the channels for the distribution block 24 in conjunction with FIG. This is the same as the first match of the channel described in .

The design of the channels for the radiating block 55 is the same as shown in FIG. radiation The design of the channels for block 35 is in distribution block 24 and related to FIG. This is the same as the second segment of the channel in the above-mentioned US patent. Ru. However, the material for the radiation block 55 must be chosen carefully.

In addition to having high heat resistance and low coefficient of thermal expansion, their The material must have high dissipation and/or the ability to undergo surface oxide deposition or coating. Must be. Its coverage is %zr! ! As mentioned above in connection with J. 1s-zo of silicon oxides or various metal oxide coatings in the wavelength range of microns. Indicates infrared radiation. Preferably, the radiant block must have a high thermal conductivity. No. The thickness of the distribution and radiation blocks depends on the type of material and the selected chamfer. It is determined based on the conventional technology for the wall.

FIGS. 3 and 4 show sections or channels, i.e. sections 28 and 28 of FIG. The gradual expansion of the channel 37 in FIG. The edges may be rather steep at first so as to form nearly vertical sides.

The use of selective screens as described above increases the radiation efficiency of the entire assembly. and must be taken into account. This arises from the following. The overall radiation is The radiating surface is a function of the intensity and the radiating surface area, but the radiating surface Dt - reaching a point of decreasing. However, a proper screen mounted on the emitting surface increases the radiated power. This is because the screen captures flue gases and This is because energy is converted into radiant energy.

Nineteenth, by using this cook 17 of gas, it is efficient by reflection. It provides a good extension of the radiation surface and at the same time completely prevents the surrounding air from reaching the radiation surface. this As already mentioned above, such a screen is made of a ceramic structure with openings in the form of a net. They may also be made from high temperature metals.

Although the above and the following disclose general embodiments, they may have different characteristics for various functions. Does the best practice include distinct materials with special properties? Including the use of reticulated material with I'm reading. This choice arises from the following.

The five critical variables for infrared emitters are surface area, temperature, and dissipation. Dissipation is material This changes with material temperature and properties, making it difficult to use materials that already have high intrinsic dissipation. By selecting, it is further released that it has a reticulated/porous structure. Dispersion increases. Although various materials have been mentioned above, porous silicon carbide is an excellent example. be.

For a given emissive material, the radiation flux/energy is seen by the absorber. increases in proportion to the total surface area of the radiator. Radiation surface in Figure 4? :Second. S, 4 As can be seen by comparing the % porous body 150 surface in Figure 2, Figure 5 Object 25. The object 45 in FIG. 6 also has approximately the same surface as the upper surface 35 in FIG. Large (top surface 35 would be a typical surface for a conventional emitter). Based on this Although the radiation surface of a conventional emitter is a relatively small portion of the total surface, the present invention The radiation surface of the emitter is approximately 100s of the entire surface.

Nevertheless, temperature of the three variables is important because the radiated output is the absolute temperature of the emitter. It may be the most important because it changes as the fourth force of the degree. But given When trying to increase the total temperature of the emitter, the output will vary depending on the nature of the surface and the temperature. deviate from the standard by This is illustrated in FIG. In Figure 5 In this case, curve (a) is that of a typical conventional emitter, and the temperature [kT・ By increasing K from to T1, the output remains essentially the same. this The factors giving rise to the situation are mentioned above and include: I'm here. Insufficient contact area between the flame and the emitter material and conventional emitters Depends on flame penetration on the transmission emitter surface. By increasing gas Rk Any further energy input will simply result in a "flame rise." Curve (b) r! , many Figure 2.5.4 is a representative embodiment, including a porous/network structure.

As you can see from the picture, the song! (b) Emitter has more surface area and higher dissipation Therefore, the radiation output at temperature T@ is equal to the curve (a) at the same temperature fT. ) is also larger than that of the conventional emitter. However, the nature of the emitter, the combustion conditions that occur within the emitter (conversion to radiation), due to the large resistance to "upward" In addition, the curve does not rise quickly and continues to rise (with a larger gas flow). ) enables a further increase in output by increasing the temperature of the emitter. did Therefore, the present invention can take advantage of high temperatures. In this way, the embodiment of the present invention When operated at the thrust temperature for the transmitter, its dissipation is within the range α6-195. It is in.

The above considerations apply to other embodiments. In that embodiment, reflective/enhancing prefers the use of highly porous/reticular layers of material rather than conventional metal screens. It is preferably carried out. This was mentioned above. In this case, the highly reflective material is It can be placed at a very short distance above the porous emitter, but it can be placed at a very short distance above the emitter. Preferably, it is bonded to a surface. This is shown in FIG. Figure 6 Fi Figure 1 FIG. 3 is a cross-sectional view of a burner assembly (without the use of clips). collection of various individuals Unit 43 raises the entire burner unit. This collective is one A first block of material consisting of a number of connected small first spaces (not shown) distribution block) 44 and a second block of material consisting of a number of small spaces connected together. It is made up of a lock (radiation block) 45. This space is inside the distribution block 44. The one in the first space is also larger.

The aggregate further consists of a number of small third spaces w, 3 that are connected together. The lock/layer companion has a reflective block 46. This space is also the second block. larger than the. The details of the first and second blocks are similar to those shown in FIG. Ru.

Although the entire assembly is physically held together as shown in Figure 1, various Preferably, the layers/blocks are bonded together for reasons discussed below. this Typical examples include pores within the first or distribution block r160-85 ppi. It has a high quality, LAS (aluminum lithium silicon) and Fi [Mull It is made from ite J. The primary radiation (combustion) block of the second box is 25-50. Li2t or silicon carbide (highly dissipating material) has porosity in the ppi range. coated or impregnated with). 3rd t or reflective (reinforcing) layer is 5-10 It has a porosity in the ppi range and is made from silicon carbide. The thickness of the layer is Although determined by various factors, typical ranges are 10-20cm for the first block and 10-20cm for the second block. The block is 2-6m% and the third block is 2-6wm.

The above-mentioned advantages of porous emitters (when not using reflected sound) are that they It can also be applied to the porous reflection described above when used with a filter. That's it, that's it It can be an effective enhancement to traditional screens. However, non- Another important feature about something like a highly porous reflective layer is that it is carbonized The cage can be made from a high temperature ceramic material such as silicon. This material materials do not degrade easily at the very high temperatures used as emitters; This results in five other advantages: It has long operating life and the advantage is high temperature It is possible to use it. This temperature increases the radiant power (see Figure 5). (see curve (b) t-). On the other hand, the conventional high temperature screen operates at a temperature of 1150℃. -yl has an operating life of only 12,000-3 oaaq. The above porous layer is It operates properly within the range of 1100-1400℃ and the radiated output does not exceed this temperature level. The lifespan of the porous layer is longer than the risk of increasing the cost of operation at a lower safety level. The size of the traditional screen used to create images is also gradually getting larger. The height at which the invention can operate If an attempt was made to operate this conventional screen at The lifespan of Fi is qualitatively reduced.

Another important feature of the invention is that conventional burners do not have reflective screens. Instead of using metal parts in various areas and even dense ceramic for the burner itself There is a possibility that you are using a book. The relatively high heat capacity of these materials The "cooling time" is relatively long (e.g. 18G - 340 seconds) when the button is turned off. ) was the result. The use of metal parts to hold together the assembly of the present invention is Although Fi is not prohibited in its optimal form, the various layers/blocks are bonded together, thereby eliminating the high heat capacity of these metal parts. Up As mentioned, the very low heat capacity of the various porous layers dominates the overall heat capacity of the assembly. very low, resulting in a "cooling time" of less than 5-10 seconds.

In addition to producing very short "cooling" periods, highly porous materials have very low thermal conductivity. Combustion and All surfaces other than those associated with reflection and reflection are Compared to the conventional aggregate surface, which gets hot enough to touch the surface, it becomes relatively cool enough to touch. ing.

Very short "cooling" and cold external surfaces containing combustible materials such as paper and textiles. This is very important in the process.

These are foolproof instructions for those operating burners and associated paper/ik production equipment. It also has important safety features from a fire hazard perspective.
