Abstract

The invention relates to a gasified coal adhesive for a lurgi gasifier and in particular to a gasified coal adhesive for a lurgi gasifier using long flame coal as a raw material, and gasified coal forthe lurgi gasifier containing the adhesive, and a preparation method for the briquette coal. The price of the adhesive is lower relatively, and the briquette coal prepared by the adhesive has the characteristics of high mechanical strength, high thermal stability and high waterproof property.

Description

technical field [0001] The invention relates to a binder for gasification briquettes for Lurgi furnaces, in particular to a binder for gasification briquettes for Lurgi furnaces using long-flame coal as a raw material, and Lurgi briquettes containing the binder. A gasification briquette for a furnace, and a method for preparing the briquette. Background technique [0002] With the improvement of the degree of mechanization of coal mining, the proportion of lump coal in the mined coal is relatively low, only about 30%, resulting in a shortage of lump coal raw materials for fixed-bed gasification using lump coal as raw material. The pulverized coal is made into briquettes, which can replace lump coal as raw material for gasifier. [0003] At present, my country's normal-pressure fixed-bed gas-making briquette technology is relatively mature. About 20 million tons of gas-making briquettes are used in the country every year. With the development of modern coal chemical indust...
