Eco Heat & Power supplies and installs biomass heating systems, solar hot water systems, solar electric systems and wind turbines. Eco Heat & Power also supplies biomass fuels for boiler systems that are used to heat homes and commercial premises. There are different types of biomass fuels, namely wood pellets, wood chips and logs. The wood pellets are biomass materials that are pressed and dried into pellets for easy burning.
The wood pellets used for biomass heating systems are crushed into sawdust with the help of a hammer-milling machine. The sawdust is then compressed under pressure in a palletising machine. During this process, the lignin present in the biomass melts and binds the fibers together. The compressed biomass material is pushed through a pellet die at 90 degrees Celsius. The lignin helps to cool the pellets and retain the pellet shape. After cooling, the pellets are packed for bulk distribution.
The stoves that use wood pellets provide 80 to 95% burning efficiency. The wood pellets offered by Eco Heat & Power burn effectively because they have low ash content and moisture. The pellet-burning appliances are 92% efficient and they burn at a high combustion temperature. Since the pellets are low in moisture, they minimize smoke levels. The wood pellets from Eco Heat & Power are available in 15kg bags or in bulk.
