    摘要： The present invention provides a top-feeding double-swirl type gasifier: a feed line through which pulverized coal is supplied by nitrogen; a distributor for dividing the pulverized coal supplied; a plurality of burner nozzles for supplying the pulverized coal, divided in the distributor, and an oxidizer; a pressure reactor in which the pulverized coal and the oxidizer react with each other to produce a flow of synthesis gas; and a swirl generator for imparting a swirling force to the oxidizer which is fed into the pressure reactor, the gasifier further comprising a slag cooling and storing container placed beneath the pressure reactor. Each of the burner nozzles consists of a triple tube having a circular cross section. The pulverized coal and carrier gas are supplied to the most central region of the burner nozzle, and an oxidizer is supplied to an annular region 34 surrounding the central region.

    摘要： A gasification system including a gasifier, a feed injector, and a fuel feed system that includes a first feed line, a second feed line, and a controller that includes a processor. The processor is programmed to enable the first feed line to supply a fuel gas into the feed injector, enable the second feed line to supply oxygen into the feed injector, receive instructions to add a slurry to the gasifier, prevent the first feed line from supplying the fuel gas into the feed injector, enable the first feed line to supply the slurry into the feed injector, enable the second feed line to simultaneously supply the oxygen and the inert gas into the feed injector, and prevent the second feed line from supplying the inert gas into the feed injector.

    摘要： In a coal gasification furnace adapted to feed pulverized coal thereinto by the use of inert carrier gas and gasify the same, any startup burner can be unnecessitated thereby eliminating any startup combustion chamber. Further, even in the use of a startup burner, it is smaller and lighter in weight than conventional startup burners, allowing the startup combustion chamber to be compact and limiting the height of the entirety of the gasification furnace. As a characteristic feature, a pulverized coal fuel supply passageway (23) to a combustor burner (9) is provided at its midstream portion with a startup gas supply passageway (29) for supply of a startup combustible gas (NG1). After reaching of the temperature of the furnace interior to a first temperature (T1) allowing ignition of pulverized coal with reference to a detected value from furnace interior temperature detecting means (41), transition to combustion by the pulverized coal and carrier gas is effected by increasing the input rate of pulverized coal and carrier gas while decreasing the supply rate of combustible gas (NG1) from the startup gas supply passageway (29).
