Biomass is biological material derived from living, or recently living, matter such as plant material, vegetation, agricultural residue, and animal and human waste. It can be used in a number of ways, such as digestion, gasification and combustion, with the latter most commonly used for the built environment.
Biomass is used for facility heating, electric power generation, and combined heat and power and can be converted into electric power through several methods. The most frequently used method is direct combustion of materials such as agricultural waste or woody materials.
Direct combustion of wood pellets, chips or logs in open fires, stoves and boilers can provide local or central heating and domestic hot water, or even feed small and large-scale district heating schemes. Most urban installations utilise wood chips or pellets as a fuel source, with pellets generally opted for as they have a higher calorific value per unit volume and are free flowing. Pellet production requires considerable energy input due to the temperature and pressures involved.
At Haydon we have extensive experience in the design, supply, installation, commissioning and operation of biomass boilers.
