Abstract: 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.

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 deformation. Continuous sweeping by gas of the annular gap between pressure shell and cooling screen is unnecessary and backflow by producer gas is prevented.

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 an oxidizing agent containing free oxygen, the cooling screen is connected to the pressure shell in a gastight manner via a sliding seal 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.

Abstract: An entrained bed gasifier for operation with particulate or liquid fuels is provided. A reaction chamber defined by a cold screen and a quenching chamber connected to the reaction chamber using a crude gas and slag outlet, wherein at least the cold screen is enclosed by a pressure-resistant pressure mantle. The annular gap between the cold screen and pressure jacket may be filled with a fluid, for example, water or heat transfer oil. A rough pressure equalization between the gasification chamber and the annual gap may be guaranteed using a connection between the annular gap and the quenching chamber or the crude gas line, hence the pressure in the gasification chamber normally remains slightly higher than in the inner water jacket.

Abstract: A method for gasification of fuel in an entrained flow of a gasification reactor. The method includes jointly gasifying a mixture of at least two different fuels having different degrees of coalification, including those of differing coal qualities such as brown coals and stone coals. The method also includes pulverizing the coals forming the mixture in specific grain bands and drying the coals forming the mixture to a specific residual water content.

Abstract: 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.
