Definitions
- Boiler made of plastic with integrated exhaust gas cleaning
- the invention relates to a boiler for liquid, gaseous and / or dusty fuels, in which the heating takes place via one or more built-in burners by direct contact of the combustion gases with a heat transfer fluid in a container and the heat of condensation of the fuel is used.
- Such a boiler is mainly used for small and medium-sized domestic heating systems, optionally with domestic water heating.
- an application also makes sense in industrial areas.
- Characteristics of the known prior art boilers for heating purposes usually heat a gaseous or liquid heat transfer medium by burning liquid, solid or gaseous fuels in a combustion chamber which consists of highly heat-resistant materials, such as steel, cast or stone walls, which comprise the withstand high combustion temperatures.
- the heat is transferred by contact of the heat carrier with the walls of the combustion chamber, which are flushed by the combustion exhaust gases.
- the combustion exhaust gases are then discharged at relatively high temperatures and pollutants through a mostly thermally insulated smoke pipe.
- Heating devices are known in which the flue gases are passed through a heat transfer fluid and thus the heat of condensation is used.
- solutions are known which are made of pollutants Neutralize condensation products, as is known for example from DE-OS 06 028, or reduce the pollutant content of the combustion exhaust gases.
- the result of the poor heat transfer is a high exhaust gas temperature and thus a poor efficiency.
- the high flue gas temperature has so far been deliberately maintained in order to avoid falling below the dew point of the flue gases and thus destroying the boiler and sooting the conventional flue pipes, or expensive materials that were insensitive to the condensation products were used.
- the combustion fumes came into the atmosphere without purification and distributed mainly sulfur oxide, carbon onoxide, carbon dioxide, nitrogen oxide and soot.
- Newer boilers now also use the heat of condensation to increase the efficiency by additional heat exchangers cooling the exhaust gases below the dew point or by the exhaust gases being in direct contact with the heat transfer fluid. be brought.
- the neutralization of the resulting condensation products is carried out in a very complex manner and thus leads to high production costs or is not provided at all.
- the condensation of the combustion exhaust gases results in large amounts of harmful, acidic condensate, operation of such a boiler without neutralization or disposal of the condensate is not possible for reasons of environmental protection.
- the aim of the invention is therefore to provide a boiler which can be operated in an environmentally friendly manner, has a high degree of efficiency and is simple and inexpensive to manufacture.
- the invention is based on the object of realizing a boiler which largely reduces, neutralizes and absorbs the pollutant content of the combustion exhaust gases by utilizing the heat of condensation and which moreover permits cost-effective production, is easy to assemble, has a low weight and is long-lasting by eliminating the risk of corrosion.
- a boiler of the type described at the outset is characterized in that the thermal shielding of the combustion chamber by means of a heat carrier fluid permits the use of plastic as material for the container of the boiler and that the heat transfer fluid at the same time has an absorption capacity. and neutralizing liquid for the pollutants extracted from the combustion exhaust gases by exhaust gas scrubbing.
- the combustion chamber which is open at the bottom, is built into the plastic container for the absorption and heat transfer liquid so that it is completely surrounded by this liquid during operation, while it is flooded with the heat transfer liquid when the boiler is idle. It was recognized that the above measures allow an inexpensive and easily processable material, ie plastic, for almost all parts of the boiler, including the container. This use of
- Plastic is associated with considerable technical progress, especially since there is no risk of corrosion with plastic parts.
- the combustion exhaust gases passed through the heat transfer fluid during operation of the boiler are distributed into small bubbles and give off almost all of their heat and the pollutants when they rise. These pollutants are collected in the corrosion-resistant plastic container of the heat transfer fluid and chemically neutralized, after which they can be disposed of in a controlled manner without affecting the environment.
- Plastic-made boilers enables a smooth operation.
- a spread of the environmentally friendly boiler according to the invention is facilitated by the low manufacturing costs and the high value retention due to the use of plastic materials as well as by simple installation and maintenance.
- F I G. 1 shows a partially sectioned schematic representation of the exemplary embodiment according to the invention during heating operation
- F I G. 2 shows a representation similar to FIG. 1, but during the break and with alternative and / or additional measures.
- a heat transfer fluid 22 which is preferably water
- the combustion chamber 4 which is surrounded by the liquid 22, can be installed in the center of the upper part of the container 1.
- the container 1 in connection with the heat transfer fluid 22 can be made of plastic, which can hold up to Temperatures of 90 to 100 ° C must be dimensionally and heat resistant.
- Plastic is easy to process, is cheaper than conventional boiler construction materials and has numerous other advantageous properties.
- Cross-linked polyethylene is preferably used. The production of plastic components with any shape is known to the person skilled in the art and does not pose any difficulties using conventional manufacturing techniques.
- the heat insulation 3 of the container 1 can be formed on the inside of the outer casing 2 using modern, known manufacturing processes. This is preferably done in such a way that the thermal insulation 3 is foamed on the inside to any thickness, so that the finished colored and structured outer jacket 2 in the same step with the insulation 3 can be trained. Additional degreasing, priming, insulation and painting or the use of cladding materials can thus be omitted.
- the thermal insulation is usually attached separately to the outside of a steel or cast iron container.
- plastics offer high resistance to chemically aggressive liquids which arise when the temperature drops below the dew point or when the condensation heat is used in a targeted manner.
- the combustion chamber 4 is located in the upper inner region of the container 1. It is preferably mounted perpendicular to the burner 14 on the top of the container 1 in such a way that the burner 14 is accessible from the outside.
- the combustion chamber 4 is open at the bottom, so that it is largely filled by the heat transfer fluid 22 in the idle or ready state without the burner 14 and its ignition device being wetted.
- the construction shown ensures that the combustion air supplied by the fan of the burner 14 can only escape downward from the combustion chamber 4, that is to say through the heat transfer fluid 22.
- the burner 14 can be a conventional burner type known per se, but preferably with a more powerful fan. A person skilled in the art can easily carry out this modification.
- the combustion chamber 4 is emptied. This is done by blowing air in through the burner fan or by creating a vacuum above the liquid 22 outside the combustion chamber 4 or a combination of both techniques. In all cases, a pressure difference is formed which presses the heat transfer fluid 22 out of the combustion chamber 4, so that the air supplied through the burner 14 can escape below the combustion chamber 4 and bubble upwards.
- the heat transfer fluid 22 previously contained therein has risen in the container 1 and now preferably covers the entire outer part of the combustion chamber 4, as can be seen from the comparative illustration between FIG. 1 and 2 emerges.
- the flame 5 burns with the supply of fuel and the combustion air supplied now in the interior of the emptied combustion chamber 4.
- the resulting combustion exhaust gases 20 escape downward through the open part of the combustion chamber
- the combustion chamber wall 24 is made of a material which is resistant to the temperatures occurring inside and the acid formation in the heat transfer fluid 22, such as e.g. Metal, ceramics, glass or plastics. Since the liquid 22 which has risen on the wall 24 causes the entire combustion chamber 4 to be continuously cooled, a material which can only tolerate low temperatures can also be used with a larger cross-section of the combustion chamber without direct contact with the flame.
- the construction of the combustion chamber 4 is designed by suitable constructional measures so that the plastic material of the container 1 is not stressed beyond its maximum temperature resistance. In any case, the combustion chamber 4 can be kept small, so that e.g. no high costs arise even when stainless steel is used.
- the combustion exhaust gases 20 exiting below the combustion chamber 4 during burner operation are exhausted distributed a device that leads to the smallest possible gas bubbles 20.
- this is a fine-meshed grid or sieve 21 through which the exhaust gases are pressed.
- this grating or sieve 21 can be excited to mechanical vibrations, as a result of which the fine gas bubbles 20 are strongly swirled.
- the now slowly swirling bubbles 20 form a turbulent foaming bath in which the heat exchangers 6, 7 for heating and process water circuits are located.
- These heat exchangers 6, 7 are designed as tube, finned tube, plate or other heat exchangers. Such constructions are known to the person skilled in the art. Stainless steel, copper or other corrosion-resistant materials are used as materials. However, according to the invention, the heat exchangers 6, 7 are preferably made of plastic. Due to the turbulent movement in the heat transfer liquid 22, the heat transfer is significantly better than in standing or only moderately agitated liquids. Plastic offers the advantage of being free of corrosion, free design of the shape and inexpensive to manufacture.
- the heat exchanger 7 can be designed such that the exhaust gas bubbles 20 come into intimate contact with the exchanger walls and a high exchanger performance is thus achieved.
- a preferred possibility is the design as a double-jacket heat exchanger 6 in the container 1. This preferably heats domestic water.
- fillers 26 can additionally be introduced into the container 1, which obstruct the movement of the gas bubbles 20 and thus cause a longer residence time in the liquid 22 and at the same time increase the reaction surface area.
- the exhaust gas bubbles 20 release not only their heat when they bubble up, but also their pollutants to the heat transfer fluid 22. This happens through chemical reactions.
- chemicals are added to the heat transfer fluid 22, for example calcium carbonate, which combines with the sulfur in the combustion exhaust gases 20 to form calcium sulfate. This achieves neutralization and retention of the sulfur that would otherwise be released into the atmosphere.
- the neutralization product which is ultimately gypsum, is removed in a thickened form at certain maintenance intervals and, according to current regulations, can be disposed of with household waste without any problems.
- the necessary chemicals can be added to the liquid 22 in liquid form, or in the form of a granular absorption and neutralizing agent 23, as shown in FIG. 2 is shown.
- it makes sense to pass the neutralization chemicals used for example as a pressed or sintered cartridge 16, through an opening Bring in contact with the liquid 22 in the container 1.
- the consumption of the chemicals can then be detected by optical control or automatically, and a maintenance message can then be carried out by a control in the control and display panel 15.
- Such a monitoring can easily be carried out by a specialist on the basis of his specialist knowledge.
- Residue products also include soot, dust and other particles as well as unburned oil components (for oil firing). These are also retained in the heat transfer fluid 22. They can also be removed at longer maintenance intervals, e.g. annually with disposal.
- a filter cartridge 17 is preferably installed in the container 1 between the riser pipe 27 and the condensate drain 18. The filter cartridge 17 serves to separate out these particles or solids, so that they can be disposed of by changing the cartridge 17. By introducing the excess condensate through the filter cartridge 17, no solid waste materials can get into the sewage system.
- the combustion exhaust gases which collect in the container 1 above the heat transfer fluid 22, have been largely cleaned and are now passed either directly or via a heat exchanger 11 through the exhaust pipe 12 into the atmosphere.
- the container 1 is sealed on all sides, so that the entire exhaust gas is forced into the exhaust pipe 2.
- the exhaust gas heat exchanger 11 is preferably designed as an air-air cross-flow heat exchanger known per se and emits the residual heat of the exhaust gases 20 to the intake combustion air.
- the temperature of the exhaust gases in the exhaust pipe 12 is therefore only slightly higher than that of the surroundings. This makes it possible to use a plastic pipe for the exhaust pipe 12, for example.
- the heat exchanger 11 in the exhaust gas stream can be designed as an air-water heat exchanger that heats water for use or swimming pool.
- the heat exchanger 11 can also be used to heat the return 10 of the heating circuit.
- the fillers 26 can be conventional fillers made of metal and / or plastic, as are used in chemical processes.
- the burner cover 13, into which the control and display panel 15 is integrated, can also be made of plastic.
- the burner 14 is of course connected to a fuel supply line (not shown).
- gas-tight and liquid-tight closable openings are provided at suitable points, through which the boiler can be serviced and disposed of.
- Known screw connections which are known per se can be used for the gas-tight and liquid-tight sealing of the container.
- a plastic powder is fed into a container 1 entspre ⁇ sponding Hohlf ⁇ rm, the supply in a Taumelbewe ⁇ rotates about two axes.
- the mold is heated in an oven to about 250 ° C, whereby the plastic powder melts.
- the wall thickness of the outer wall 2 of the container 1 formed in this way is determined by the amount of the powder.
- the internal insulation 3 is foamed.
- the insulating material thickness of the insulation 3 is determined by the amount of the plastic powder and the blowing agent.
- a second smaller container heat exchanger wall of the double jacket heat exchanger 6
- the inner and outer containers can be sealed by fusing or gluing. If a removable lid is required for the container 1, it can be made in one of these steps. 2. Injection molding process
- PE polyethylene
- GRP fiber-reinforced plastics
- foamed sheet goods such as FOREX or K ⁇ MACEC (from Kömmerling) can be used to manufacture the outer jacket and insulation in one step.
- FOREX or K ⁇ MACEC from Kömmerling
- the outer jacket and insulation can also be produced from this.
