The Industrial Use of Biomass Pellet Fuel (BY James Wang) Wood pellets have gained a lot of popularity as alternative source of energy for industrial uses. These pellets are made from sawdust and wood shavings. They are used in automatic wood boilers that are convenient and highly efficient. Because of their low moisture and ash content, the wood pellets burn in an efficient burner. To make matters even better, they are very easy to store. The industrial use of biomass fuel is mainly heating and production of electricity. In the industrial use of biomass pellet fuel, briquetting describes the process of converting loose biomass residues such as rice husk, straw, sawdust in to solid blocks of high density which can be used as fuel. The biomass briquettes replace the wood or fossil fuels for industrial processes. They are easier to handle and cleaner and are very important in reducing green house gas emissions that leading cause of global warming. A high pressure pellet making machine can produce briquettes worth more than 200 tones in one day. How does the briquetting work? There are two major approaches to briquetting namely the high pressure and low pressure briquetting. For high pressure briquetting, there are three types of equipments. One of these equipments is the pellet mill which works by compressing the raw biomass between rollers leading to the production of cylindrical pellets. Another is the screw press which uses tapered screw for the production of briquettes that are longer and hollow. The piston press uses oscillating piston for the compression of biomass to produce cylindrical briquettes.
