Abstract

The invention relates to a gasification furnace, and more specifically relates to a fixed bed slag gasification furnace material distributing temperature controlling device. The fixed bed slag gasification furnace material distributing temperature controlling device is arranged on a gasification furnace, and comprises a buffer cabinet (1); the buffer cabinet (1) is arranged above a gasification furnace material inlet (2); the upper part of the buffer cabinet (1) is provided with an opening, the lower part is communicated with a gasification furnace material inlet (2); the upper part of the buffer cabinet (1) is provided with a material inlet spray head (3); the material inlet spray head (3) is communicated with a flowing raw material inlet pipe (4); the flowing raw material inlet pipe (4)is provided with a material introduction adjusting valve (5). The fixed bed slag gasification furnace material distributing temperature controlling device is capable of mixing raw materials introducedinto the gasification furnace to be more uniform, and realizing in time regulation, so that stable temperature control of the upper part of the gasification furnace and product gas is realized.

Description

technical field [0001] The invention relates to a gasification furnace, in particular to a material distribution temperature control device for a fixed bed slag gasification furnace. Background technique [0002] In the existing fixed bed slag gasification technology, raw coal and other solid carbon-containing substances are sent into the furnace from the top of the gasifier, and heavy oil and other fluid gasification raw materials are sent into the furnace from the body of the gasifier. Oxygen and water vapor are introduced into the fuel bed for gasification under high pressure and high temperature. The product gas produced by gasification is collected from the upper space of the gasifier and sent to the subsequent treatment process from the product gas outlet. [0003] The applicant found that when the bed fluctuates or the feed uniformity and ratio of raw coal and other carbonaceous substances fluctuate, the temperature of the product gas in the upper space of the gasifi...
