How does the Proposed Biomass Project Work?

Plan of Operation – Furnace

  • Fuel is burned in the combustion chamber, generating heat.

  • Normal wood burning gases -ventilated and trapped by a cyclone, which will lower emissions when compared to a residential wood stove

  • Ash is evacuated onto a conveyor below the furnace, to a bin, for regular disposal in the Val d’Or landfill.

  • Heat is transferred to “thermal oil” in a large heat exchanger located above the boiler’s combustion chamber. This oil is circulated and has no emissions.

  • Thermal oil is pumped to a second heat exchanger located in the ORC building, transferring heat to the turbine.

Plan of Operation – Generator

  • Heat exchanger transfers heat to a second working fluid.   

  • Fluid vaporizes, increasing pressure in the generation chamber.

  • High pressure gas enters ORC turbine and turns turbine fan blades;

  • Gas is piped back to an external air-cooled condenser, and turns it into liquid

  • ‘Closed loop’, so zero gas emissions, just like a home radiator

  • Monitored onsite through a six-screen office, and remotely 24/7 by the equipment suppliers

Fuel Supply and Harvesting

  • No harvesting activities within the community or on the traditional lands of Barriere Lake.

  • One truck load per day is all that is required

  • Community – final approval on the fuel supply arrangements, which means every year the community will select where the fiber will come from.

  • All fuel will come from outside harvesters utilizing waste wood from their harvesting activities. 

  • Normally this fiber is wasted because it is burned on the roadside of logging operations.

  • Uses everything the forest gives us, so nothing goes to waste

  • ABLFN can establish:

    • Harvesting crews to clean up the nearby lands and bring material to the biomass plant as fuel. Reforestation can occur.

    • Its own resource management regime and take over management of the lands from the Province of Quebec.
