How Circulating Fluidized Bed Boilers Work? - Bright Hub .

Fluidized Bed. At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air supply is from under the bed at high pressure. This lifts the bed material and the coal particles and keeps it in suspension. The coal combustion takes place in this suspended condition. This is the Fluidized bed.

As a new mature high-efficiency and low-pollution clean coal technology, circulating fluidized bed combustion is low-temperature combustion, so the NOx emission is much lower than that of pulverized coal furnace, only 100ppm. CFBC can desulfurize directly during the combustion process, and the desulfurization efficiency is high.

Fluidized Bed Combustion System. Fluidized bed combustion systems are able to reduce SOx by primary measures only down to approximately 150 mg/m3 STP by means of adding dolomite directly into the coal feed where it reacts with the sulfur to form CaSO4 (gypsum), with the result that no further bonding agent is required for the ash product to set when water is added.
