The use of biomass energy has the potential to greatly reduce greenhouse gas emissions. Burning biomass releases about the same amount of carbon dioxide as burning fossil fuels. Biomass energy supports agricultural and forest-product industries. The main biomass feedstocks for power are paper mill residue, lumber mill scrap, and municipal waste.

The briquettes produced by a screw press is easily handled and stacked, and they have some advantages over those produced using the ram and die press, such as better efficient combustion due to the central hole and carbonized outer layer. The major residues are rice husk, coffee husk, coir pith, jute sticks, bagasse, groundnut shells, mustard stalks and cotton stalks. Sawdust, a milling residue is also available in huge quantity. Apart from the problems of transportation, storage, and handling, the direct burning of loose biomass in conventional grates is associated with very low thermal efficiency and widespread air pollution. We introduced all the types of charcoal briquette machines to them, one is screw type, the second is hydraulic type, the third is punch type, the forth is mechanical type, and the last one is roller type. For coal materials, high carbon, low moisture, low sulphur, low ash content, that is the good-quality coal. If the ash content is high, that means the quality of coal is not good. 

Our technicians have abundant bruiquetting production experience and can guide you to intall the whole production line exactly. Especially for coal briquette press machine, we control the setting angle of the screw properly. The briquette machine can make you produce briquettes more easily and smoothly. Below is the process from Fote Machinery-Biomass Charcoal-Briquetting. Use this method on how to make charcoal briquettes, and produce your own homemade ones. 

Both national and international agencies have funded projects to improve the existing coal briquette press machine technology. The two major impediments for the smooth working of the screw press -- the high wear of the screw and the comparatively large specific power consumption required --were overcome by incorporating biomass feet preheating into the production process.
