Fluidized-bed boilers are the most common type of boilers recommended for biomass fuel. The fuel is suspended by an upward flow of combustion air through a bed of hot, inert particles, allowing oxygen to reach the combustible material more readily.
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
