brûleur de biomasse

CONT: Le combustible de bois sec est mélangé à de la sciure de bois vert afin de produire un mélange de combustible qui convienne aux brûleurs de biomasse [...]

OBS: Primary combustion air comes from above the grates, not below.
CONT: 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.
