Effect of Bed Pressure Drop on Performance of a CFB …

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

Fluidized Bed Gasifier - an overview | ScienceDirect Topics

The fluidized bed boiler is gaining in popularity and has overtaken the grate-fired boiler in biofuel power generation applications. The principle is very simple: air is blown through a bed of sand and fuel particles at a velocity that is sufficient to suspend the particles on the airstream but not able to lift them permanently out of the bed, that is, 1–3 m s −1 at 800–900 °C.

Gas Concentrations in the Lower Part of the Combustion …

7/10/2000 · The effect of the height of the bottom bed on the conditions in the lower part of a 12 MW CFB boiler was studied. Pressure measurements along the furnace height were made together with gas (CO, hydrocarbons, O2, NO, and SO2) and zirconia-cell probe measurements in the splash zone. The operation in the exploding bubble regime causes the particulate phase to be under reducing conditions. However
