Canadian company to debut new biomass boiler technology

By Anna Austin | October 18, 2011

Calgary, Alberta, Canada-based Firebox Energy Systems Ltd. has announced plans to build a 30-megawatt (MW) biomass power plant on the designated lands of Alexis Nakota Sioux Nation Reserve #133 near Glenevis, 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.

When the biomass plant is complete in early 2013, it will send 97 percent of its electrical output to the grid, according to Janus, and 3 percent will be utilized at an industrial combined-heat-and-power greenhouse that the Alexis Nakota Sioux will own and 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.

    The design of Gas Turbine appears to be unique.

    This is very good for the environment; hopefully this company will get a big success promoting the technology.

    There is nothing unique about this....its an indirect system which is how all steam powered turbines work. In steam turbine power plant facilities the steam is generated in a separate steam boiler using whatever fuel source is desired, steam is generated in the boiler and the steam is then routed to a steam turbine that generates electricity..... this is elementary!!!! If Firebox intends to use superheated air instead of steam the system will be far less efficient, would need substantially larger facilities with a substantially higher capital requirements ....... for what a less efficient system???? This smells of a scam more then anything

    The efficiency is the key here simply heating air and directing towards a turbine is not how it works. The air needs to pass through the compressor side of the turbine, then to the heater and as it is superheated it will expand like a combustion gas and spin the turbine as it passes through it. However, the compression cycle can take up about 30% to 60% of the energy produced. And if you are talking about producing 30MW of power that is a huge turbine. The biggest air turbine project to date was only 5MW so this is a big jump. It will be interesting to see if it works.
