Abstract

The invention relates to a clean type coal only taking starch as a binder and a preparation method thereof. The clean type coal only taking the starch as the binder is prepared from, by weight, one ormultiple of anthracite, extracted low-volatile semi-coke, coking coal powder and an thraciteslime and starch serving as the binder. According to the clean type coal only taking the starch as the binder and the preparation method thereof, the problems are solved that in the prior art, the cost of coal is high, in the combustion process, harmful gas is generated and volatilized, inorganic viscosityis low, the product yield is low, the strength is low, and transportation is difficult.

Description

technical field [0001] The invention relates to the field of clean briquettes, in particular to a clean briquette using only starch as a binder and a preparation method thereof. Background technique [0002] As we all know, coal is an unclean solid fuel energy source, which has a serious impact on air pollution after combustion. At present, the country is governing the environment to reduce the pollution caused by coal-burning emissions to the atmosphere. Local governments have introduced corresponding control measures, requiring people to use energy such as heating in their daily lives. Use clean briquettes. Briquette is a kind of clean briquette, and many domestic and foreign enterprises are researching, developing and applying clean briquette technology. Clean briquettes are optimized combinations of raw coals with different characteristics. Coal resources are different in different regions. The use of binders, combustion improvers, additives, etc. that do not cause seco...
