All About Briquettes
Briquettes are made from agricultural products waste and are a replacement for fossil fuels such as oil, gas or coal, and can be used to heat boilers in manufacturing plants, and also have applications in developing countries. Briquettes are a renewable source of energy and avoid adding fossil carbon to the atmosphere.
A number of companies in India have switched from gas to briquettes to save costs on boiler fuels. The use of briquettes is predominant in the southern parts of India, where coal and gas are being replaced by briquettes. . Use of briquettes can earn Carbon Credits for reducing emissions in the atmosphere.briquettes also provide more calorific value/kg and save around 30-40 percent of boiler fuel costs.
A popular briquette emerging in developed countries takes a waste produce such as sawdust, compresses it and then extrudes it to make a reconstituted log that can replace firewood. It is a similar process to forming a wood pellet but on a larger scale. There are no binders involved in this process. The natural lignin in the wood binds the particles of wood together to form a solid. Burning a wood briquette is far more efficient than burning firewood. Moisture content of a briquette can be as low as 4%, whereas green firewood may be as high as 65%.
