Applications for Biomass:
District energy systems use one or more central plants to provide thermal energy to multiple buildings.
Gasification is a thermo-chemical process that converts solid fuel materials into combustible gases that can then be used for heat and power.
Fully automated systems employ a chip storage bin, typically below grade, that can hold one and a half to two tractor loads of woodchips (35-50 tons).
Fully automated woodchip heating systems, which feed the chips from the storage bin automatically to the boiler, can be very expensive. A more cost-effective alternative for smaller facilities with lower heating loads is the semi-automated system.
Biomass projects that generate electrical power at industrial locations also generate enough heat to be productively used. Making use of this waste heat increases a project's overall cost efficiency.
