Entrained-flow gasifier with cooling screen and bellows compensator

ENTRAINED-FLOW GASIFIER WITH COOLING SCREEN AND BELLOWS COMPENSATOR Abstract In a reactor for the gasification of solid and liquid fuels in the entrained flow at temperatures between 1200 and 1900 *C and pressures between ambient pressure and 10 MPa with an oxidizing agent containing free oxygen, the cooling screen is connected in a gas-tight manner to the pressure shell via a bellows compensator to accommodate linear 5 deformation. Continuous sweeping by gas of the annular gap between pressure shell and cooling screen is unnecessary and backflow by producer gas is prevented. to Fig. 1 TRN- R6RQRQ pilot burner gas 51---6 ...

ENTRAINED-FLOW GASIFIER WITH COOLING SCREEN AND SLIDING SEAL Abstract In a reactor for gasification of entrained solid and liquid fuels at temperatures between 1,200 and 1,900*C and at pressures between ambient pressure and 10 MPa using s an oxidizing agent containing free oxygen, the cooling screen is connected to the pressure shell in a gastight manner via a sliding seal (13, 14) in order to allow length changes. Continuous gas purging of the annular gap between pressure shell and cooling screen is unnecessary and gasification gas is prevented from flowing behind.

Simultaneous gasification of coals of widely differing degrees of coalification in entrained flow gasification

The invention relates to a gasification method which, with a reliable and safe mode of operation, allows the simultaneous gasification of coals of different degrees of coalification, including those of differing coal qualities such as brown coals and stone coals, with the pulverized fuel consisting of the mixture of the different coals being fed from a common dispensing system to the gasification reactor.

Entrained flow reactor for gasifying solid and liquid energy sources

There is described a reactor for entrained flow gasification for operation with dust-type or liquid fuels, wherein a number of gasification burners are disposed away from the reactor axis, with the center line of a gasification burner having an oblique position that is other than parallel to the reactor axis, it being possible for said oblique position to extend at different angles up to an angle of 90°. The center line does not necessarily have to intersect the reactor axis; rather the center line can pass the reactor axis at a predetermined distance. This arrangement is associated with a significant reduction in the unwanted discharge of dust-type fine slag, which is difficult to utilize, in conjunction with the possibility of reducing the reactor diameter due to its structure.
