Embodiment Construction

[0068] Hereinafter, one embodiment will be described with reference to the drawings regarding the start-up method of the gasifier, the gasifier, and the combined coal gasification power generation facility of the present invention.

[0069] The gasifier described below is used in e.g. figure 1 The shown integrated coal gasification power plant (hereinafter referred to as "IGCC") 1 is used as an apparatus for injecting pulverized coal (powdered coal) into a furnace to generate combustible gas (coal gas). It should be noted that, in the following description, the coal gasifier 10 that generates combustible gas from pulverized coal is exemplified, but the gasifier of the present invention can also be applied to, for example, thinning wood, waste wood, driftwood, grass, waste Gasification of other solid carbonaceous fuels such as waste, sludge, tires and other biomass fuels.

[0070] figure 1 The IGCC 1 of the first embodiment, which shows a schematic configuration example, incl...

Abstract

A gasifier start-up method for a gasifier capable of preventing or inhibiting a temporary occurrence of black smoke when a gasifier is started-up. A gasifier start-up method for a gasifier, in which a gasifying agent and a solid carbonaceous fuel are supplied and gasified, includes a start-up burner igniting step of supplying a start-up fuel and oxygen-containing gas to a start-up burner and igniting the start-up fuel and oxygen-containing gas, under an inert atmosphere in which an inside of the gasifier around the start-up burner is filled with inert gas; and an oxygen-containing-gas supply adjusting step of adjusting the supply of the oxygen-containing gas such that combustion gas obtained after the combustion reaction of the start-up fuel and the oxygen-containing gas becomes the inert gas, which contains little oxygen.

Description

technical field [0001] The present invention relates to a start-up method applied to a gasification furnace such as integrated gasification combined cycle (IGCC) and the like, in particular to a flare system of the gasification furnace. Background technique [0002] As we all know, combined coal gasification power generation equipment (IGCC) is a power generation equipment that achieves higher efficiency and higher environmental friendliness than conventional coal-fired thermal power generation by combining gasification of coal with combined cycle power generation. This coal gasification composite power generation facility also has a great advantage in being able to use coal which is abundant in resources, and the advantage is further increased by expanding the types of coal used. [0003] Conventional combined coal gasification power generation facilities generally include a coal supply device, a coal gasifier, a char recovery device, a gas refining facility, a gas turbine ...
