Fluidized bed combustion systems use a heated bed of sand-like material suspended(fluidized) within a rising column of air to burn many types and classes of fuel. This technique results in a vast improvement in combustion efficiency of high moisture content fuels, and is adaptable to a variety of "waste type" fuels. The scrubbing action of the bed material on the fuel particle enhances the combustion process by stripping away the carbon dioxide and char layers that normally form around the fuel particle. This allows oxygen to reach the combustible material much more readily and increases the rate and efficiency of the combustion process.  3, fiche 1, Anglais, - fluidized%20bed%20system

The boilers are fed wood fuel from the main fuel bin located adjacent to the boiler house. The boilers are the "pile burner" type, which burn wood in a large pile on the floor of a refractory lined furnace box. Combustion efficiency with this type of boiler is generally low but pile burners are simple and therefore relatively inexpensive. Low combustion efficiency also means that emissions such as particulates and carbon monoxide are relatively high. One notable advantage to these systems is that high moisture content fuels can be burned as well as "dirty" fuels containing debris.  3, fiche 2, Anglais, - pile%20burner

Pile burner : Boilers incorporating a pile burning design find applications where the anticipated wood fuel has a high(up to 65%) relative moisture content, as is found in whole green tree chips, bark, and green mill residue. Grates serve to support the fuel, and underfire air flowing up through the grates provides oxygen for combustion, cools the grates, promotes turbulence in the fuel bed, and dries the fuel. The most common form of pile burning is the Dutch oven, which was used almost exclusively during the early part of the century(Guinn and Turner 1990).  4, fiche 2, Anglais, - pile%20burner
