Abstract

The invention belongs to the field of coal gasification, and relates to a gasifier and a gasification method, in particular to a gasification agent strong-rotation pulverized coal gasifier and a gasification method. The problems that the inner wall face of an existing gasifier is likely to be abraded, a center recirculation zone of the gasifier is not stable, and partial burning is caused, so that the gasifier halts, and economic losses are caused to enterprises are solved. The gasification agent strong-rotation pulverized coal gasifier comprises a pulverized coal nozzle, a gasifier body, a water wall, a synthesis gas channel pipe and gasification agent nozzles. The gasifier body is composed of a hemispheroid and a cylinder. The water wall is installed inside the gasifier. The water wall is composed of a plurality of vertical circular pipes side by side. A gasification hearth is a revolution solid formed by the water wall. A slag basin is located at the bottom of the gasifier body. The synthesis gas channel pipe is inserted at the lower portion of the gasifier body. The gasification agent nozzles are sequentially and uniformly distributed from top to bottom and arranged on the side wall of the upper portion of the gasifier body side by side. The pulverized coal nozzle is installed on the top of the gasifier body.

Description

technical field [0001] The invention relates to a gasification furnace and a gasification method, in particular to a gasification agent strong rotating pulverized coal gasification furnace and a gasification method, belonging to the field of coal gasification. Background technique [0002] Coal gasification technology is an efficient and clean clean coal technology. Gasification agent strong rotary pulverized coal gasification technology is a new type of dry pulverized coal gasification technology, which has the advantages of high gasification intensity, large production capacity, high carbon conversion rate, and strong applicability of coal types. It has begun to emerge in the field of coal gasification. In order to solve the problems of short burner life and uneven slag hanging on the inner wall of the gasification furnace in the existing pulverized coal gasification technology, the applicant applied for a series of Chinese patents related to the gasification agent strong ...
