Embodiment Construction

[0024] figure 1 The output cone 1 shown in is advantageously divided in manufacturing technology into several sections and comprises an inner cone forming a fluidization zone 2 , a solids output zone 3 and a cone bottom 4 . According to the invention, the output cone can also be configured as a component (not shown here) with the properties according to the invention.

[0025] The fluidizing zone 2 is formed by a pressure-resistant housing 5 , an inner cone 6 located in the housing, a fluidizer supply 7 , and two connecting flanges 8 a, 8 b.

[0026] The output cone 1 is connected to a solid storage container not shown in the figure via a connecting flange 8a. The wall of the inner cone is configured as a wall area through which the fluidizer can pass, with the angle α 1 Also denote the opening angle relative to the vertical or relative to the direction of gravity (arrow "g").

[0027] The fluidizing agent (arrow 9 ) flowing through the fluidizing agent supply 7 is distribu...

Abstract

With an apparatus for supplying multiple burners with fine-grained fuel from a storage container, with thermal conversion of solid fuels in a gasification reactor, wherein the storage container is equipped with a discharge cone, a solution is supposed to be created with which the required excess gas amounts can be reduced and it is possible to do without separate discharge cones per burner line, without giving up the uncoupling of the burner lines. This is achieved in that the discharge cone (1) is equipped, at least in certain regions, with a gas-permeable wall region (6, 6′) and with at least two solids discharge lines (15) that lead to the burners.

Description

technical field [0001] The invention relates to a device for supplying a plurality of burners with fine-grained fuel. Background technique [0002] When thermally converting solid fuels such as different coals, peat, hydrogenation residues, residues, waste, biomass, fly ash, or mixtures of the above fuels under high pressure, it is necessary to The lower stored feedstock is brought to a pressure level for thermal conversion so that it can be transported to the pressure reactor. Possible thermal processes are, for example, pressurized combustion or high-pressure vaporization in the fluidized-bed or impinging-flow process. [0003] Metering of fine-particle fuel from the storage vessel and feeding it to the burner is a prerequisite for optimal operation of the gasifier. [0004] One possibility for dosing consists in fluidizing the storage container like a fluidized bed (EP 0 626 196 A1 / DE 41 08 048 A1). The disadvantage of this solution is that, on the one hand, a large am...
