Abstract

The invention relates to a gasifier and a gasification method and in particular relates to a gasifier device and method for gasifying pulverized coal by simultaneously feeding gasifying agents from a top burner and a furnace body layer by layer and strongly rotating the gasifying agents, aiming to solve the problem in the prior art that slag adheres to the walls of gasifiers non-uniformly, thus causing burning loss and corrosion of inner walls of the gasifiers. The gasifier device is characterized in that a plurality of gasifying agent nozzles are uniformly formed in the upper part of a gasifier body from top to bottom in sequence; nozzle centers of the plurality of gasifying agent nozzles are in a same vertical line vertical to the horizontal plane; a pulverized coal burner is installed at the top of the gasifier body; a gasifying agent channel with a ring-shaped cross section and a pulverized coal channel with a ring-shaped cross section are arranged in the pulverized coal burner; swirl vanes are arranged at the ends, near fire, of the gasifying agent channel and the pulverized coal channel; and a gas flow control valve is arranged on each gasifying agent nozzle. The gasifier device and the method belong to the field of coal gasification.

Description

technical field [0001] The invention relates to a gasification furnace and a gasification method, in particular to a device and a gasification method for simultaneously feeding a gasification agent into a strong rotating pulverized coal gasification furnace from a top burner and a furnace body in layers, and belongs to the field of coal gasification. Background technique [0002] Coal gasification technology is an efficient and clean clean coal technology. The current coal gasification technology is mainly divided into four categories: moving bed gasification, fluidized bed gasification, entrained flow gasification and molten bed gasification. Among them, entrained bed gasification technology has become the main development direction of coal gasification technology due to its advantages of high gasification intensity, large production capacity and high carbon conversion rate. Entrained bed gasification has two main features. One is the high operating temperature, about 1300...
