Definitions

  • the invention relates to a gasification boilers for the combustion of solid fuels, especially straw bales, for heating and hot water production.
  • the invention is characterized by optimum combustion and ash separation. This ensures that the prescribed exhaust gas values are complied with.
  • the principle of fuel gasification in a combustion chamber and the post-combustion in a separate combustion chamber has significant advantages for particulate fuels. These are mainly a far-reaching, clean combustion, so low environmental impact and high energy yield.
  • the known designs consist of a closed fuel filling chamber with filling door, a lower combustion and gasification zone, a lower grate and combustion nozzle with an underlying or behind the combustion chamber, air ducts, heat exchangers and ash separator.
  • One Such boiler for solid combustion is exemplary in the DE OS 34 08 602 and DE PS 37 18 022 described.
  • special air and fuel gas ducts have been proposed.
  • the hopper has the shape of a double cone with Gasabströmö réelleen and a torch channel in the extension. This is intended to bring about a uniform burnup and simple construction.
  • the fuel grain straw bale causes special requirements. There is the problem of uniform gasification which is hampered by charring the outer layers. A high content of unburned small components and a low ash melting point have an unfavorable effect on the exhaust gas values and pollute the heat exchange surfaces ( DE OS 41 34 754 ).
  • the object of the invention is to carry out the combustion of small parts as completely as possible and to separate the ash almost completely already before the heat exchangers from the fuel gas.
  • the fuel and gasification chamber has recesses laterally adjacent to the centrally located grate and the combustion chamber.
  • coarse particles collect, while only the fines with the fuel gas are carried in the combustion chamber.
  • the coarse parts can outgas in the wells and do not burden the fuel gas flow. After completion of the combustion, the remaining ash can be removed there.
  • a cylindrical combustion chamber designed as an additional structural unit is connected to the outlet of the combustion chamber.
  • a cylindrical, ash separator designed as an additional structural unit is connected to the combustion chamber.
  • the remaining ash components are removed from the flue gas.
  • the subsequently arranged heat exchanger is thus no longer burdened with ash.
  • a fuel and gasification chamber 1 and below a lying, cylindrical combustion chamber 3 is arranged.
  • a straw bale loading door and two ash removal doors are attached to the front.
  • a longitudinal slot in the ground is present, which extends over the entire depth.
  • a 2 grate is taken in.
  • gas nozzles which open into a combustion chamber 6. This consists of sections of refractory concrete, which are guided in a steel tube.
  • the fuel and gasification chamber 1 has parallel to the grate 2 and the combustion chamber 3 recesses 4. These are half-shell-shaped.
  • the wall has in each case a door to ash removal in the end.
  • the boiler with fuel and gasification chamber 1 and combustion chamber 3 is designed as a structural unit.
  • the downstream combustion chamber 5, ash separator 6 and heat exchangers are combined by a frame 10 to form another unit.
  • Combustion chamber 5 and ash separator 6 have a vertical, cylindrical housing.
  • the walls of the housing are insulated, the top of which are closed by a cup-shaped lid.
  • an annular guide plate (8) is mounted so that the outer wall remains an annular opening for the ash precipitate.
  • the subsequent heat exchangers are arranged in a vertical flue gas outlet.
  • the combustion gases have by a circulating air blower in the fuel and gasification chamber 1 a rotational movement.
  • the loose, heavy particles of the combustible material accumulate in the outer, lateral depressions 4 and burn out completely there. Light suspended particles are entrained with the fuel gas stream and completely burned at the latest in the combustion chamber 5.
  • the ash separator 6 there is a multiple separation of the ash. When the gas flows in the ash particles are pressed against the inner wall and fall during the deflection by the baffle 8 down. The ash removal takes place through the upper cover 7, 9 and a door in the bottom region of the ash separator 6. The thus purified gas stream is passed through the heat exchanger.
