Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of briquette and its production method, which solves the problem that the coal itself has high hardness, high elasticity, poor hydrophilicity and poor molding effect in the briquette forming, and it is necessary to add a bonding agent with complex components and high cost. However, conventional components such as clay do not burn and remain in the burned cinder as intractable solid waste

Abstract

The invention discloses a briquette and a production method thereof. The briquette is prepared from the following raw materials in parts by mass: 1-1.5 parts of slack coal, 0.5-1 part of fine coal, 0.1-0.5 part of gelatin, and 0.1-0.5 part of basic zinc carbonate. Through adoption of the briquette and the production method thereof, the comprehensive utilization ratio of coal powder is improved; the briquette is enabled to have high hot and cold intensity, further, less adhesive is used, and post-combustion solid wastes are reduced.

Description

technical field [0001] The invention relates to the technical field of coal mine processing, in particular to a molded coal and a production method thereof. Background technique [0002] The particle size of the coal block is an important physical parameter of coal combustion, and the particle size significantly affects the temperature of the combustion flame, the degree of burnout and the emission of nitrides and sulfides. Pulverized coal refers to coal with particle size less than 6mm. Generally speaking, the utilization value of pulverized coal is worse than that of lump coal of the same quality. [0003] With the improvement of the level of fully mechanized mining and the increase of the proportion of coal mining in the lower group, the content of pulverized coal continues to increase. In addition to long-distance transportation, a considerable part of the raw coal that reaches the user is pulverized coal, which leads to the contradiction between the supply of lump coal...
