Coal briquettes Lignite briquette Coal briquette. Coal briquettes have long been produced as a means of using up 'small coal', the finely broken coal inevitably produced during the mining process. Otherwise this is difficult to burn as it is hard to arrange adequate airflow through a fire of these small pieces; also such fuel tends to be drawn up and out of the chimney by the draught, giving ...

Life cycle assessment further shows that the biocoal production process could achieve net positive energy, financial, and environmental benefits. By using available biomass wastes as feedstock, China is expected to have a total biocoal production of 402 million tons of standard coal equivalent, which is equal to 13% of national coal consumption.

Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal ), and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer.

The process of burning smokeless coal involves up to 20 times less gas and particulate matter than burning wood. ... The production of smokeless wood involves a careful drying and treatment process to reduce its moisture content significantly. The lower moisture content ensures that the wood burns more efficiently and produces less smoke.

Abstract. Briquette binder plays a key role in the process of briquette production. The quality and performance of briquette also depend on the quality of briquette binder. Different types of briquette need different briquette binder. Binder used in briquetting process can be divided into inorganic binder, organic binder and compound binder.
