Effect of Bed Pressure Drop on Performance of a CFB Boiler

The effect of bed pressure drop and bed inventory on the performances of a circulating fluidized bed () was studied By using the state specification design the fluidization state of the gassolids flow in the furnace of conventional was reconstructed to operate at a much lower bed pressure drop by reducing bed inventory and control bed quality Through
