The effect of bed pressure drop and bed inventory on the performances of a circulating fluidized bed (CFB) boiler was studied. By using the state specification design theory, the fluidization state of the gas−solids flow in the furnace of conventional CFB boilers was reconstructed to operate at a much lower bed pressure drop by reducing bed inventory and control bed quality. Through
The Circulating fluidized bed coal fired boiler contains mainly particles of an inert material, like sand and ash, including particles of SO2 sorbent. The coal content in a fluidized bed is not considerable, it is only from 3 to 5% of the whole mass of the bed. CFB boilers are touted for their fuel flexibility.
