Problems solved by technology

[0002] At present, the fuel used for boilers is mainly bulk raw coal. During use, the blackness of the flue gas is large, the environmental pollution is serious, and the transportation and storage are extremely inconvenient. It is difficult to guarantee that the calorific value is low, resulting in insufficient combustion, and a lot of smoke and dust are generated during combustion. The emission of smoke and dust not only pollutes the environment, but is also not conducive to the health of producers

Embodiment 1

[0007] Embodiment 1: A kind of industrial anthracite briquette, it is made up of anthracite, cement, lightly burned powder, plain carbon, oxygen promoter, water, and the ratio of each component is, anthracite 40, cement 2, lightly burned powder 5 , plain carbon 5, oxygen promoter 2, water 20.

Embodiment 2

[0008] Embodiment 2: A kind of industrial anthracite briquette, it is made up of anthracite, cement, lightly burned powder, plain carbon, oxygen promoter, water, and the ratio of each component is, anthracite 55, cement 10, lightly burned powder 3 , plain charcoal 10, oxygen promoter 1, water 50.

Embodiment 3

[0009] Embodiment 3: A kind of industrial anthracite briquette, it is made up of anthracite, cement, lightly burned powder, plain carbon, oxygen promoter, water, and each component ratio is, anthracite 45, cement 8, lightly burned powder 4 , plain charcoal 8, oxygen promoter 1, water 30.

[0010] In each of the above examples, the coal should generally be pulverized to a particle size of no larger than 3mm. Other particle sizes can also be used if the process requirements are met.

[0011] 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 anthracitic shaped coal which is characterized by being prepared from the following components in parts by weight: 40-55 parts of anthracite coal, 2-10 parts of concrete, 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 very high heat productivity reaching 25000-32500 kJ / kg, higher release temperature of volatile content, anthracitic combustion, reduced pollutant gas emission, neutral coal cinder and less environmental pollution by adding the anthracite coal with high carbon content to the shaped coal.

Description

technical field [0001] The invention relates to a briquette, in particular to an industrial anthracite briquette. Background technique [0002] At present, the fuel used for boilers is mainly bulk raw coal. During use, the blackness of the flue gas is large, the environmental pollution is serious, and the transportation and storage are extremely inconvenient. It is difficult to guarantee that the calorific value is low, resulting in insufficient combustion, and a lot of smoke and dust are generated during combustion. The emission of smoke and dust not only pollutes the environment, but is also not conducive to the health of producers. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art and provide an industrial anthracite briquette. [0004] The object of the present invention is achieved in this way, a kind of industrial anthracite briquette, is characterized in that: it is made up of anthracite, cement,...
