Abstract
Method and equipment for producing coke (PC) during indirectly heated gasification, in which coal particles are supplied to a gasification reactor (1) and process gas (P) supplied during the gasification is reduced in it to synthesis gas (S), whereby the synthesis gas (S) is removed from the gasification reactor (1). The method is distinguished in that at the same time a gasification takes place, a coking of coal takes place in an inner reactor (4) arranged inside the gasification reactor (1), that the inner reactor (4) is indirectly heated, that coke (PC) and combustible gases are produced in the inner reactor (4) during the coking, and that the combustible gases are used for the indirect heating in the gasification in the gasification reactor (1).
Claims16
A method for producing coke during indirectly heated gasification, comprising:
- supplying coal particles to a gasification reactor;
- supplying process gas during the gasification, the process gas being reduced to synthesis gas (S);
- and
- removing the synthesis gas from the gasification reactor, wherein
- at the same time a gasification takes place, a coking of coal takes place in an inner reactor arranged vertically inside the gasification reactor, the inner reactor is indirectly heated, coke and combustible gases are produced in the inner reactor during the coking, and the combustible gases are used for the indirect heating in the gasification in the gasification reactor, and during the production of coke and combustible gases in the inner reactor the coal travels downwards in the inner reactor and the combustible gases travel upwards in the inner reactor.
An apparatus for producing coke during indirectly heated gasification, comprising:
- a gasification reactor;
- burners arranged in the gasification reactor that generate radiant heat;
- an injection nozzle for supplying coal particles and process gas to the inside of the gasification reactor, that a
- an inner reactor arranged vertically in the gasification reactor, and that the inner reactor being formed in such a manner that coal particles pass the inner reactor during coking,
- means for conducting combustible gases produced during the coking from the inner reactor to the burners, wherein
- the apparatus is configured that during the production of coke and combustible gases in the inner reactor the coal travels downwards in the inner reactor and the combustible gases travel upwards in the inner reactor.
