Northampton Circulating Fluidized Bed Power Plant - Power

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.

Combustion of anthracite culm in a fluidized bed boiler

For anthracite culm, combustion in conventional boiler systems is difficult to achieve due to the fuel's high ash content, high moisture content, and low heating value. However, the burning of culm in a fluidized bed system was demonstrated at a steam generation plant in Pennsylvania. A
