Circulating fluidized bed boiler | Water tube boilers

Circulating Fluidized Bed (CFB Series) Combustion technology utilises the fluidized bed principle in which crushed fuel is injected into the furnace or combustor and the fine combusted particles are elutriated out of the furnace with flue gas. The balance particles are then collected by solid separators and circulated back into the furnace.

Northampton Circulating Fluidized Bed Power Plant -

Combustion in the Northampton plant takes place in a hot 'fluidized' bed, consisting of culm, silt (another anthracite waste by-product) limestone (to absorb sulfur) and ash. NOx emissions are minimized thanks to the boiler's relatively low combustion temperature (approx. 920°C) and the long residence time of the fuel in the furnace.
