Description

High-durability smokeless barbecue charcoal and preparation method thereof Technical Field The invention relates to the technical field of solid fuels, in particular to high-durability smokeless barbecue charcoal and a preparation method thereof. Background Barbecue is widely favored by people because of the open and free dining environment and form, and the main fuels used in barbecue are charcoal, coal, coke, bamboo charcoal and the like, but the existing heat sources have the defects of short burning time of charcoal and bamboo charcoal, a large amount of smoke exists in coal burning, the coke is not flammable and the use is difficult. And the combustion time is short, and the smoke generated by combustion or nonflammable combustion can cause serious environmental pollution and waste of resources. The environment pollution of the current society is serious, the government advocates environmental protection, and outdoor barbecue is forbidden by many places.
