fluidized bed boiler flue gas calculation

Fluidized Bed Boiler - an overview | ScienceDirect Topics

The circulating fluidized bed (CFB) boiler (see Figure 8) takes the principle of the bubbling bed one step further and with increased fluidization velocity the particles are lifted out of the bed and follow the gas out of the combustion chamber. They are then separated from the gas in a cyclone or beam separator and returned to the bed.

A STUDY OF THE DESIGN OF FLUIDIZED BED REACTORS FOR

Fluidized bed combustion is a widely used technology for producing energy. The process is designed principally for the combustion of solid fuels such as coal or biomass. A conventional circulating fluidized bed boiler (see Figure 1), or a CFB, comprises a combustion chamber, a separator, and a return leg to circulate the bed particles. The bed material is composed of sand, fuel ash, and some sulfur capturing

TO CALCULATE AND IMPROVEMENT IN THE EFFICIENCY OF FBC

01/12/2019 · The current measurement results indicated that at full boiler load the calculated mercury emission factors for fly ash and flue gas (Hg 0 +Hg 2+) were 4.186 μg/MJ and 1.215 μg/MJ, respectively, while the calculated factor for total emission of mercury was roughly 5.401 μg/MJ.

Theory and Calculation of Heat Transfer in Furnaces

The height of the fluidized bed is 0.40.8 m resulting in a 612 kPa pressure drop over the bed. The bed material is sand and fuel ash. If sulfur capture is necessary, limestone is also fed into the furnace, and the reaction products (limestone) will form part of the bed material.
