Wood Gasification Boilers
What is a wood gasification boiler?
A wood gasification boiler is one that combusts the gases created during the burning of wood. The combustion process in a wood gasification boiler is achieved at very high temperature – about 1000-1200 degrees. This means that the construction of the wood gasification boiler needs to be reinforced and with better insulation that a regular wood burning boiler. The most characteristic feature of every wood gasification boiler is that it has two combustion chambers. The upper combustion chamber is where the wood burns and due to the low oxygen levels, they begin to smolder. This causes the gases to be transferred to the lower combustion chamber where the process of gasification (or pyrolysis) begins. It is very important for every wood gasification boiler that the wood has moisture level of below 20%, otherwise the gasification process can’t be achieved.
Due to the increasing energy efficiency requirements, every wood gasification boiler offered by Balkanenergy complies with the European standard EN 303-5, and the models of BURNIT have recently acquired BAFA certification.
