Problems solved by technology

[0004] In response to this market situation, we found that semi-coke, as a by-product of coal chemical industry, has a large quantity and low price, and its performance is much better than that of anthracite, but because semi-coke does not have the viscosity of anthracite, it is difficult to form as the main raw material of civil briquette. The thermal strength is not as high as the finished product produced with anthracite, and the thermal stability is also poor and the finished product has a high ignition point, which is not easy to ignite

Abstract

The invention provides environment-friendly clean coal for civil use and a preparation method thereof. The environment-friendly clean coal is prepared from, by weight, 80%-94% of semi coke, 5%-20% of shaped coal binder and 3%.-17% of shaped coal additive. The environment-friendly clean coal has the advantages that on the condition that a coal chemical product of semi coke which is low in cost is utilized, and a compound type binder and an efficient multifunctional additive taking a by-product of an agricultural product of straw as the main material is added, the use cost of the clean coal is reduced to the maximum extent.

Description

technical field [0001] The invention relates to the field of briquette manufacturing, in particular to an environment-friendly civil clean briquette and a preparation method thereof. Background technique [0002] Coal has been recognized as the cheapest energy source. The energy waste and environmental pollution caused by the direct combustion of raw coal are obvious to all. To change this situation, the method of burning briquette coal, which is energy-saving and environmentally friendly, is Simple yet effective method. [0003] The preparation and use of briquettes has a long history. Up to now, scholars at home and abroad are still further researching and improving, and countless patents have appeared and applied. However, there are still problems in the production process of briquettes that are not environmentally friendly. Low, high ash content, low calorific value, high volatile content, it is difficult to meet the use requirements. Especially the fatal shortcoming t...
