Definitions
- the invention relates to a reactor for gasifying granular fuels, the fuel forming a fixed bed in the reactor, into the lower region of which oxygen-containing gasifying agent is introduced, which moves upwards in the fixed bed, and wherein product gas containing hydrogen and carbon oxides is removed above the fixed bed through a discharge duct from the Discharges reactor.
- the invention is based on the object of designing the reactor mentioned at the outset in such a way that even in the case of a strong product gas stream, no disruptive amounts of fine-grained fuel are drawn off from the reactor.
- This is achieved according to the invention in that at least one centrifugal separator for separating solids from the product gas is arranged in the reactor, which has an inlet opening for dust-containing product gas coming from the fixed bed, an outlet line for product gas and a solid discharge line leading into the fixed bed, the outlet line with the discharge channel of the reactor is connected.
- centrifugal separators are arranged in the reactor, the outlet lines of the separators in one in the upper region of the reactor arranged annular chamber open, which is connected to the discharge channel.
- An expedient development of the invention consists in that a vertical ring wall is arranged in the upper area of the reactor and that the inlet opening of the separator is located outside the reactor area enclosed by the ring wall.
- the ring wall ensures that the inlet opening of the separator is above the fixed bed.
- the reactors usually operate at pressures from 1 to 80 bar.
- Fig. 1 shows a gasification reactor with a rotating grate in
- FIG. 2 shows a second reactor variant in the representation analogous to FIG. 2 and FIG. 3 a further reactor variant.
- the reactor of FIG. 1 has a housing (1) which is usually water-cooled.
- the granular fuel comes from a storage container (2) and falls through the then opened valve (3) onto the fixed bed (4).
- a rotating grate (5) In the lower area of the reactor there is a rotating grate (5), which is mixed with a gasification medium line (6) Feeds oxygen and water vapor, which is distributed from the rotating grate (5) into the fixed bed (4). In a manner not shown, ash is drawn down through the opening (7).
- a vertical ring wall (10) is connected to the reactor housing (1) in a gas-tight manner at the upper end and serves as a boundary for an annular chamber (11) which is connected to the discharge channel (9).
- a horizontal partition (12) is arranged in the form of an annular disc between the housing (1) and the annular wall (10) as the lower boundary of the annular chamber (11).
- Fig. 1 two cyclones (13) are shown, the outlet lines (14) lead upwards into the annular chamber (11).
- the inlet opening (15) of each cyclone (13) is located below the partition (12) and above the fixed bed (4). Dust-containing product gas, which flows out of the fixed bed (4), forcibly enters through the openings (15) into one of the two cyclones (13), with the separated solids being discharged through the respective solid matter discharge line (16) back into the fixed bed (4) become.
- the lower area of the discharge line (16) is widened for better drainage of the solids downwards.
- the number of cyclones can be chosen arbitrarily, it will usually be 1 to 10.
- the product gas, which leaves the cyclones (13) flows through the outlet lines (14) first into the annular chamber (11) and then to the exhaust duct (9). The dust content of this product gas is limited in this way, so that malfunctions are avoided.
- the cyclones (13) are within the area enclosed by the ring wall (10) and thus more or less in the fixed bed (4), where the temperatures are relatively low.
- the cyclones (13) are located outside the ring wall (10) and the product gas flows around them.
- the reference numerals of FIG. 2 have the meaning already explained together with FIG. 1.
- a gasification reactor with a rotating grate (5) can easily be equipped with only a cyclone (13) according to Fig. 3, and also the reactor of Fig. 3, the trigger more fluid Slag works, have several separating cyclones (13), as was explained together with FIG. 1 or FIG. 2.
