Technology of Biomass Briquettes

Biomass Briquettes are made from agricultural waste and are a replacement for fossil fuels such as oil or coal, and can be used to heat boilers in manufacturing plants, and also have applications in developing countries. Biomass briquettes are a renewable source of energy and avoid adding fossil carbon to the atmosphere.

 

More and more companies in developing countries have switched from furnace oil to biomass briquettes to save costs on boiler fuels. The use of  Biomass Briquettes is predominant in the deveoping countries, where coal and furnace oil are being replaced by Biomass Briquettes . More and more people are using Biomass Briquettes as boiler fuel. Use of  Biomass Briquettes can earn Carbon Credits for reducing emissions in the atmosphere. Lanxess India and a few other large companies are supposedly using Biomass Briquettes for earning Carbon Credits by switching their boiler fuel. Biomass Briquettes also provide more calorific value/kg and save around 30-40 percent of boiler fuel costs.

 

A popular Biomass Briquettes emerging in developed countries is one which takes a waste produce such as sawdust, compresses it and then extrudes it to make a reconsistuted log which can replace firewood. It is a very similar process to forming a wood pellet but the size of final products is bigger. 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%, where as green firewood may be as high as 65%.

 

Sawdust briquettes have developed over time with two distinct types: those with holes through the centre, and those which are solid. Both types are classified as briquettes but are form using different techniques. A solid briquette is manufactured using a piston press which simple sandwiches layers of sawdust together, and ones which a hole are produced using a screw press. The hole is simply a by product of the screw thread passing through the centre however it also increases the surface area of the log and aids efficient combustion.

 

Anyang general international Co.,Ltd is a leading company for screw type briquette machine in china and has exported to many countries especially middle and east European countries, the Biomass Briquettes machines are popular there for small scale individual user.
