Definitions

  • the invention relates to a solid gasification boiler with a filling shaft and a gasification chamber arranged above a grate, and to a method for operating such a solid gasification boiler.
  • the invention has for its object to provide a solid gasification boiler, which can be used for small businesses and households and with which heat can be generated directly, so that, for example in small industrial companies, agricultural companies, garden centers and households or the like. Not only the elimination of Waste can be carried out sensibly, but heating of the operating systems is also possible at the same time with the energies obtained.
  • coal, peat and other combustible materials can be processed and waste or other residues can be burned at the same time.
  • These different fuels can be gasified and burned at the same time and can be filled into the furnace unsorted.
  • the fuel gas obtained is of high combustion quality and, depending on the gasified substances, has little or no oil or tars in the exhaust gases.
  • the gasification of the different fuels and the subsequent burning of the resulting gas burns out the materials up to 99%. As a result, a particularly high level of energy is achieved.
  • ash is produced to an exceptionally small extent, which is an unmelted, sterile ash in a floury state. The ashes can immediately be fed from the furnace to a corresponding collection container.
  • Fig. 1 denotes a filling shaft of a solid gasification boiler.
  • a rotary valve or a double piston filler can be provided here.
  • a reaction or gasification chamber 2 At the bottom of this filling shaft is a reaction or gasification chamber 2, which is delimited at the bottom by a grate 3, which is shown in the drawing as a swivel grate.
  • a combustion chamber 4 is arranged below the swiveling grate 3 and is delimited at the bottom by an ash extraction 5.
  • a vibrating grate can also be used, which is driven by a vibrating motor drive.
  • a flame tube 6 Provided within the combustion chamber 4 is a flame tube 6, the gas inlet 7 of which is arranged eccentrically to the combustion chamber 4, so that the combustion gases escaping downward through the swiveling grate 3 are forced to enter the flame tube eccentrically, while doing so at a pipe socket 8 arranged support burner 9 must flow past, which is intended to ignite the gases to be burned in the flame tube 6.
  • the pipe socket 8 is closed to the outside by an explosion flap 10 with a draft limiter.
  • a blower which opens into the lower region of the combustion chamber 4 via air lines 12, leads into the swiveling grate 3 via a further air line 14 and mün into the upper region of the reaction chamber 2 via a third air line 15 det, below the filling shaft, and in these three areas for the supply of oxygen-rich fresh air.
  • a pressure compensation tube is shown, which leads from the filling shaft into the reaction chamber 2 and via a bypass line 16a into the combustion chamber 4.
  • An ignition burner 17 which is also arranged in a corresponding pipe socket 18, opens into the reaction chamber 2 above the swivel grate 3.
  • the swiveling grate 3 has a width which is greater than the clear width of the reaction space 2.
  • the swivel grate extends over the entire length of the boiler and has in the areas in which it lies below the projecting wall parts 19 and 20 of the reaction chamber 2, on the swivel grate plane upward protrusions 21, which prevent ungased fuel from the reaction chamber 2 can get into the combustion chamber 4.
  • the wall of the solid gasification boiler can accommodate a heat exchanger 22, for example the heat exchanger of a hot water heater.
  • the solid gasification boiler described above works in the combustion chamber 4 and in the flame tube 6 with a vacuum which extends to the filling shaft 1.
  • the negative pressure in the filling shaft 1 and in the reaction chamber 2 decreases and can come to zero, depending on how the pressure control system is switched on represents is.
  • the natural chimney draft or a built-in flue gas fan ensure the negative pressure in the solid gasification boiler. This negative pressure is guaranteed when the boiler is started up by a pressure control system, so that no excess pressure can arise due to excess gas production.
  • the pressure control system controls the air supply to the boiler. If there is a large amount of gas in the reaction chamber 2 and in the filling shaft 1, as a result of which the vacuum would decrease, the air supply is immediately reduced or completely closed. This can be done using a separate control system or by appropriately controlling the blower 11.
  • the pressure compensation tube 16 leading from the filling shaft 1 into the reaction chamber 2 or into the combustion chamber 4 can be arranged inside or outside the boiler and ensures a constant pressure inside the boiler.
  • the flame tube 6 is, as already described, arranged so that the gas inlet 7 has the effect that the gases emerging downwards through the swiveling grate 3 must pass through a further path to the outlet and are thus guided past the support burner 9. As a result, the gases are burned in the combustion chamber 4 and completely burned out in the flame tube 6.
  • a heat exchanger can also be connected, so that the burnt-out gases in the flame tube 6, which can have a temperature between 500 and 800 ° C, ge in the heat exchanger can be cooled and then discharged through the chimney with a low exhaust gas temperature of approx. 100 °.
  • the flame tube 6 itself is made of a heat-resistant material, for example stainless steel or a quartz melt, this material becoming red-hot and thus ensuring better combustion in the flame tube 6 and in the combustion chamber 4.
  • the shape of the flame tube 6 is irrelevant.
  • the arrangement of an explosion valve 10 with draft limiter has the task that in the event of deflagrations within the boiler, these can be compensated for immediately.
  • the draft limiter closes as soon as the blower 11 is in operation. If the blower 11 turns off or the air supply is completely or partially closed, the draft limiter 10 comes into operation and regulates the draft in the combustion tube, so that the solid gasification boiler in the reaction chamber 2 and in the combustion chamber 4 does not cool down.
  • the swivel grate 3 is driven with a thrust safety device, which has the task of absorbing the force of the motor when materials in the reaction space 2 jam or tilt, so that the swivel grate 3 cannot move freely.
  • the fuel materials prepared in this way are filled into the filling shaft 1.
  • these substances are ignited via the swiveling grate 3 and heated up to 1000 ° C., as a result of which gasification occurs and a fuel gas is produced which is of high fuel gas quality and burned depending on the type Residues have no or only little occurrence of oils and tars.
  • This fuel gas is sucked down by a negative pressure in the lower combustion chamber 4, ignited via the pilot burner 17 and then burned further in the combustion chamber 4 and in the flame tube 6.
  • the burned-out exhaust gases have a temperature of between 500 and 800 ° C and can then be passed through a heat exchanger to obtain the residual energy and can be removed through the chimney, with an exhaust gas temperature in the chimney of approximately 100 ° C then.
  • the solids can also be mixed with flammable liquids, with the boilers according to the invention e.g. the problem-free burning of waste oil is possible.
