Abstract

The invention relates to a composition for preparing coal briquette. The composition comprises blind coal, coke powder, glutinous rice flour and sodium chloride. The coal briquette prepared from the composition has a fairly ideal calorific value, and does not cause pollution on the environment, and especially, coal slime is added to the composition, so that the surface of the coal briquette is smooth; the coal briquette is not easily crushed; and a certain amount of pulverized coal is generated even if the coal briquette bears large friction force, so that waste of resources can be avoided.

Description

technical field [0001] The invention relates to a composition for making briquettes. Background technique [0002] Traditional briquettes are usually mixed with clay and lime and then pressed into shape. Although this kind of briquettes can make pulverized coal into briquettes, their calorific value and strength are relatively low, and slagging will occur after burning, which will easily affect coal burning. The furnace burns normally. For this reason, Chinese Patent No. 1891797A discloses a kind of solution titled "tempered anthracite coal ball". The briquettes use anthracite and low-sulfur coal, and a plasticizing agent, wherein the plasticizing agent is composed of cement. Although the proposed briquettes can solve the problems of low strength and hardness, high calorific value and no slagging after combustion, since cement is a non-combustible material, if the cement content is too low, the strength and hardness of briquettes cannot be improved. , if the cement conten...
