Definitions

Gasification boiler for solid fuels especially for straw bales, with optimized exhaust gas values
the invention relates to a gasification boiler for the combustion of solid fuels, especially straw bales, for heating purposes and hot water production.
the invention is characterized by optimal combustion and ash separation. This ensures that the prescribed exhaust gas values are adhered to.
the filling shaft has the shape of a double cone with gas outflow openings and a fuel ring channel in the extension. This is to achieve a uniform burn-up and simple construction.
DE PS 3617146 shows a special air supply for the primary air in order to achieve a good fuel gas / air mixture.
the blower is mounted on the filling door and feeds outside air into three levels of the fuel shaft.
the solution in DE PS 3718022 contains two air supply levels in the fuel shaft and one to the combustion chamber. Particularly good gasification is to be achieved with the recirculation of exhaust gas.
the straw straw bale fuel has special requirements. There is the problem of uniform gasification, which is hindered by charring of 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 contaminate the heat exchange surfaces (DE OS 41 34 754).
the object of the invention is to carry out the combustion even of small parts as completely as possible and to separate the ashes from the fuel gas almost completely before the heat exchangers.
the fuel and gasification chamber has recesses on the side next to the grate arranged in the center and the combustion chamber. Coarse particles collect in these, while only the fine particles with the fuel gas are carried into the combustion chamber. The coarse parts can outgas in the wells and do not burden the gas flow. After the combustion is complete, the remaining ash can be removed from there.
a cylindrical combustion chamber designed as an additional structural unit is connected to the outlet of the combustion chamber. This post-combustion chamber significantly increases the combustion time, which means that small parts and partially oxidized gases are completely burned. The tangential introduction of the fuel gas acts like a cyclone, so that more ash collects on the floor. This can be removed through a lid.
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 subsequent heat exchanger is no longer loaded with ash.
the interaction of the three structural features thus results in more complete combustion, improved ash separation and thus lower exhaust gas pollution.
the maintenance and service life of the heat exchanger are also improved.
FIG. 1 shows a gasification boiler in front view in section
Figure 2 shows the side view of the entire heating system in
Figure 3 is a plan view of the entire heating system.
a fuel and gasification chamber 1 and a lying, cylindrical combustion chamber 3 are arranged in a housing.
a filling door for the straw bale and two doors for ash removal are attached to the front.
At the lower vertex of the fuel and gasification chamber 1 there is a longitudinal slot in the floor, which extends over the entire depth.
a grate 2 is embedded in this.
Below the grate 2 there are gas nozzles which open into a combustion chamber 6. This consists of pipe sections made of refractory concrete, which are guided in a steel pipe.
the fuel and gasification chamber 1 has depressions 4 parallel to the grate 2 and combustion chamber 3. These are half-shell-shaped. In the end area, the wall has a door for removal of ashes.
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 exchanger are combined into a further structural unit by a frame 10.
Combustion chamber 5 and Aseheabscheider 6 have a vertical, cylindrical housing.
the walls of the housings are insulated, at the top they are closed by a bowl-shaped cover.
a pipe is centrally located in the ash separator in the upper area and a circular baffle (8) is attached below it in such a way that an annular opening for the ash deposit remains on the outer wall.
the subsequent heat exchangers are arranged in a vertical flue gas outlet.
the combustion gases have a rotational movement due to a forced air fan in the fuel and gasification chamber 1.
the loose, heavy particles of the firing material collect in the outer, lateral recesses 4 and burn out there completely.
Light floating particles are entrained with the fuel gas flow and completely burned in the combustion chamber 5 at the latest.
the ash separator 6 the ash is separated several times. When the gas flows in, the ash particles are pressed against the inner wall and fall downward when deflected by the guide plate 8.
the ash is removed through the upper covers 7, 9 and a door in the bottom area of the ash separator 6.
the gas stream cleaned in this way is passed over the heat exchangers.
