New biomass boiler technology being trialled

Friday 4 Nov 2011

 
Canada-based Firebox Energy Systems Ltd. has announced plans to build a new 30-megawatt (MW) biomass power plant in Alberta. The $60 million John W. Murray Biomass Plant will essentially serve as a demonstration facility for the company’s platform Air Boiler technology, said CEO Jason Janus.

Describing the technology, Janus said the system is designed so that only clean hot air moves through the turbine itself. “Compared to a traditional gas turbine, rather than the combustion of fuel occurring within the turbine, the Air Boiler system places the fuel combustion in the flexible fuel furnace that’s adjacent to the turbine, and the overall system is designed to collect the heat generated inside the furnace and utilize it for the turbine’s operation.”

Since the combustion of the fuels and the resulting exhaust gases are always kept separate from the turbine operation, the quality of the fuel source doesn’t matter, he added, and the system does not require the use of water to operate.
Janus said fuel for the plant will be forest debris, including pine beetle damaged wood. If the plant proves successful, plans are in the works for a much larger, 270-MW power facility on the same land. Source: Biomassmagazine.com
