Circulating fluidized bed - Wikipedia

Solid fuel added to the bed will burn in the oxygen-rich conditions inside the bed created by the primary air. There are two types of fluidized beds: in bubbling fluidized beds the bed particles are kept in suspension at relatively low fluidization velocities whereas in circulating fluidized beds, particles are carried out of the bed at higher fluidization velocities and are separated in a cyclone and reintroduced back into the bed.

How To Calculate Natural Gas Boiler Consumption--ZBG

The boiler gas consumption calculation need the following parameters: such as natural gas calorific value 8500kcal/m3, pressure 8-10Kpa, and theoretically, the gas consumption of boiler heat = boiler calorific value÷(Calorific value of natural gas x Boiler …

Circulating Fluidized-Bed Boilers - Babcock & Wilcox

Most of the early BFBs used tubular air heaters to minimize air leakage that could occur as a result of relatively high primary air pressures required to suspend the bed. Recent designs have included regenerative type air heaters. Circulating fluidized bed combustor . A typical CFB arrangement is illustrated schematically in figure.
