How Circulating Fluidized Bed Boilers Work? - Bright Hub
Jan 28, 2015 · With several years R&D, ZG boilers Circulating Fluidized Bed (CFB) boiler is characterized by its compatibility with a wide variety of fuels including: low-grade coal, biomass, sludge, waste plastics, etc., whereas conventional boilers for power generation are available only for fossil fuels, such as high-grade coal, oil and gas. As the needs for a fuel shift are rising in response to the current CO2
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
Circulating Fluidized-Bed (IR-CFB) Boilers. Drawing upon our extensive technical expertise and operating experience, B&W developed the Internal Recirculation Circulating Fluidized-Bed (IR-CFB) boiler which is the technology of choice for power plant owners seeking economy, reliability and flexibility. In addition, load-following capabilities are attainable with B&Ws in-bed heat exchanger technology.
