Circulating fluidized bed(CFB) boiler working principle

Jan 28, 2015 · With several years R&D, ZG boiler's 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 …

Fluidised Bed Combustion System (FBCS): Working, Types

Fluidised bed firing is well suited for low grade fuels. In a CFB boiler, fuel is fed in a stream of fluidised hot solids consisting mainly of fuel ash and limestone. Efficient cyclones ensure extended residence times allowing full combustion at a temperature lower than in conventional pulverised fuel firing.
