Abstract

The invention relates to a gasifier, in particular to a gasifier device combining a water wall with refractory brick wall surfaces and aims to solve the problems that refractory brick wall surfaces of gasifiers in the prior art are prone to damage during burning, and water wall surfaces has large heat loss and are easy to block. A coal powder burner is mounted at the top of a gasifier, the water wall is mounted in the gasifier, a synthesis gas channel is mounted in the lower part of the gasifier, and a slag tank is mounted at the bottom of the gasifier; a bend section is mounted at the upper end of a first vertical section, one end of a horizontal section is mounted at the lower end of the first vertical section and toward the outside of the gasifier, the other end of the horizontal section is connected with a second vertical section, the second vertical section is located at the lower end of the horizontal section, one end of an oblique section is connected with the lower end of the second vertical section, one end of the oblique section is inclined towards the inner side of the gasifier, and the refractory brick inner walls are attached to the horizontal section, the second vertical section and the oblique section of the water wall. The gasifier device is used for the field of coal gasification.

Description

technical field [0001] The invention relates to a gasification furnace device, in particular to a gasification furnace device in which a water wall and a refractory brick wall are arranged in combination. 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. In the prior art, the furnace walls of entrained bed gasifiers are mainly divided into two types, one is refractory bricks, and the other is water-cooled walls. For the wall of refractory bricks, in the actual operation process, the slag produced...
