Abstract

The invention discloses a briquette containing a composite binder and a burning synergistic agent. The briquette contains raw material components of coal powder, the composite binder and the burning synergistic agent, wherein the composite binder comprises pregelatinized starch, clay and polyvinyl alcohol; and the burning synergistic agent comprises potassium permanganate, sodium chloride and sodium carbonate. The briquette has the advantages of being easy to burn, high in cold-hot strength, high in heat efficiency, little in equipment investment, low in production cost, friendly to environment and the like.

Description

technical field [0001] The invention relates to the technical field of coal processing, in particular to a molded coal containing a composite binder and a combustion synergist and a preparation method thereof. Background technique [0002] Briquette refers to the artificial "lump coal" that processes pulverized coal with a certain particle size into a certain shape, size, strength and physical and chemical properties with appropriate technology and equipment. Briquette has the advantages of simple process, low investment and low cost. And it can obtain the advantages of improving coal quality, improving combustion efficiency, and reducing coal pollution, so it is widely used as fuel in people's daily life and industrial production. [0003] Since the end of the 19th century, the development of briquette technology has gone through three stages: (1) simply pulverized coal briquetting, (2) pulverized coal molding and modification, (3) expanded application of briquette and effi...
