Embodiment 1

[0008] Embodiment 1: a kind of industrial briquette, it is made up of bituminous coal, cement, light burning powder, plain carbon, oxygen promoter, water, and each component ratio is, bituminous coal 30, cement 2, light burning powder 5, plain Charcoal 5, oxygen promoter 2, water 20.

Embodiment 2

[0009] Embodiment 2: a kind of industrial briquette, it is made up of bituminous coal, cement, lightly burned powder, plain carbon, oxygen promoter, water, and each component ratio is, bituminous coal 20, cement 10, lightly burned powder 3, plain Charcoal 10, oxygen promoter 1, water 50.

Embodiment 3

[0010] Embodiment 3: a kind of industrial briquette, it is made up of bituminous coal, cement, lightly burned powder, plain carbon, oxygen promoter, water, and each component ratio is, bituminous coal 25, cement 8, lightly burned powder 4, plain Charcoal 8, oxygen promoter 1, water 30.

[0011] In each of the above examples, the coal should generally be pulverized to a particle size of no larger than 3 mm. Other particle sizes can also be used if the process requirements are met.

[0012] Various processes (such as material selection, crushing, mixing, molding, drying, etc.) involved in the production of coal briquettes in the present invention can adopt existing technologies or any other suitable technologies.

Abstract

The invention relates to shaped coal, in particular to industrial shaped coal which is prepared from the following components in parts by weight: 20-30 parts of bituminous coal, 2-10 parts of cement, 3-5 parts of light burning powder, 5-10 parts of prime carbon, 1-2 parts of pro-oxygenic agent and 20-50 parts of water. Compared with the prior art, the invention has the advantages of most adhesion, higher heat productivity, long combustion flame with much smoke in combustion, convenient use and rapid firing because the bituminous coal with the carbon content of 75-90 percent and without free humic acid is added to the shaped coal.

Description

technical field [0001] The invention relates to a briquette, in particular to an industrial briquette. Background technique [0002] At present, the fuel used for boilers is mainly bulk raw coal. Raw coal refers to the raw coal excavated from the ground or underground that has been screened and processed to remove gangue and pyrite. The processed raw coal is also called raw coal. Raw coal includes natural coke and low-quality coal, excluding low calorific value coal. During the combustion process of raw coal, the blackness of the flue gas is large, the environmental pollution is serious, and the transportation and storage are extremely inconvenient. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art and provide an industrial briquette. [0004] Technical scheme of the present invention is as follows: [0005] An industrial briquette, characterized in that: it is composed of bituminous coal, cement, li...
