Abstract (en)

[origin: EP3540031A1] The present invention provides a method and an apparatus for implementing gasification by combining circulating fluidized bed and pyrolysis bed, which relates to coal gasification technologies. The method comprises: first implementing pyrolysis and gasification of raw coal by using a circulating fluidized bed gasifier (2) to convert the coal to a gas without producing pollutants, such as tar, performing gas-solid separation by using a cyclone separator (3); and then, gasifying and burning out separated semi-coke and the like by using a pyrolysis bed gasifier (11), and introducing the gasified gas after removing fly ash through a deposition chamber (4) into a gas delivery pipe. The technical solution achieves a high raw coal gasification rate, produces no pollutants, such as tar, during gasification, is applicable to equipment with large, medium, and small gasification capacities, and has a large adjustment range of gas yield per unit time.
