Title:
THERMAL DECOMPOSITION COAL GASIFICATION METHOD AND THERMAL DECOMPOSITION COAL GASIFICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/129434
Kind Code:
A1
Abstract:
Disclosed is a thermal decomposition coal gasification method using an upper/lower chamber two-level gas current layer reactor (20) comprising an upper level with a cylindrical gasification furnace and a lower level with a cylindrical reforming furnace (1) connected by an enlarged diameter portion throat (3) therebetween, wherein at least coal and an oxygen-containing gas are introduced into the gasification furnace, gasified gas is generated by partial oxidisation of the coal, the gasified gas is introduced into the reforming furnace (1), at least coal is input into the reforming furnace (1), the coal added to the reforming furnace is thermally decomposed by the sensible heat of the gasified gas and so generates a generated gas containing at least hydrogen gas and carbon monoxide gas. The coal input into the gasification furnace is input conveyed by air currents in a circumferential direction so as to create a rotational flow inside the gasification furnace, and the coal input into the reforming furnace (1) is input conveyed by air currents in a circumferential direction opposite to the direction of rotational flow in the gasification furnace.
