What is biomass heating system?
Wood-fuelled heating systems, also called biomass systems, burn wood pellets, chips or logs to provide warmth in a single room or to power central heating and steam boilers, rotary drum dryers, industrial kilns, furnaces etc.
A stove burns logs or pellets to heat a single room - and may be fitted with a back boiler to provide water heating as well. A boiler burns logs, pellets or chips, and is connected to a central heating and hot water system. A wood-fuelled biomass boiler could save you up to £960 a year compared to an old electric heating system.
Benefits of biomass heating.
Greenvinci biomass gasification burner with biomass heating system has the following benefits of biomass heating:
1. Energy Saving
With semi-gasification combustion technology, biomass fuel can be fully burned, the thermal efficiency up to 93%, can save about 30% fuel consumption than biomass fuel directly fired.
2. Cost Saving
All the forms of biomass or solid fuels , such as wood chips, wood blocks, wood-wastes , palm shell , fruit shell and briquettes can be used. Customer can use the cheapest biomass fuel in local to save cost.
In general, to replace gas, LPG, CNG, FO etc. High cost fuel with biomass, can save cost up to 30%-70%.

3. Environment Friendly.
High temperature pyrolysis gasification combustion, lower emission of dust, CO, NOX and no black smoke, is a cost-effective alternative to highly polluting fuels.
