Document Type and Number:

WIPO Patent Application WO/2013/165122

Kind Code:

A1

Abstract:

The present invention relates to a cylindrical non-melt and partial melt type entrained flow bed gasifier with one or more burners mounted on the top thereof for supplying pulverized raw coal and oxidizer thereto, wherein each of the burners comprises three or four pipes so as to form a central supplying line for injecting the pulverized coal with a carrier gas into the gasifier, a primary oxidizer annular region around the central supplying line having a plurality of primary oxidizer supplying bores for injecting primary oxidizer vertically or at an angle to the injection region of the pulverized coal supplied through the central supplying line so as to direct the pulverized coal to the central region, and an outer cooling annular region around the primary oxidizer annular region for flowing cooling water, which is operated preferably at a temperature range of 1,250~1,450°C, or of 1,150~1,500°C according to the properties of the coal. According to the present invention, the pulverized coal and oxidizer are properly mixed, and the pulverized coal is directed towards the middle of the gasifier, so that the reaction is completed with the ash being wholly non-melted or partially melted.
