Circulating Fluidized-Bed Boilers - Babcock & Wilcox

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.

Circulating Fluidized Boiler. For low-grade and difficult-to-burn fuels such as anthracite, lignite, petroleum coke, oil shale, discarded coal and biomass, GE offers circulating fluidized bed (CFB) technologies with different arrangements suited to fuel. GE CFB technology has low inherent NOx emissions at 50-200 mg/Nm3 due to the following features

Alstom introduces advanced circulating fluidised bed boiler

Dec 01, 2019 · Abstract. The paper deals with the determination of mercury balance for a hard coal-fired circulating fluidized bed boiler operated at various loads (i.e. , 75% and 50% of the Maximum continuous rating, MCR). The research was focused on the determination of the mercury balance by providing data on Hg content in fuel, limestone sorbent, and in the combustion by-products (fly ash …

The effect of circulating fluidized bed boiler load on the

Circulating Fluidized Bed (CFB) Boilers. A circulating fluidized bed (CFB) boiler features higher gas velocity (superficial flow velocity) in the furnace (combustor) compared with a bubbling fluidized bed (BFB) boiler. The boiler activates a mixture of particles and gas to improve combustion reaction. Moreover, the fluid sand and fuel issuing out of the furnace are collected in a cyclone and recirculated into the furnace again, thereby improving combustion …

Boiler Tuning: Boiler Control Systems Tuning Methods

A boiler in which the combustion unit includes a fluidized bed which may be fluidized in a non-uniform manner to effect circulation of the bed material. Heat exchange takes place between the combustion products and working fluid located in tubes located above the fluidized bed and also, optionally, within the fluidized bed.
