Thermal efficiency measures how well a CFB boiler’s heat exchanger transfers heat from the combustion process to the water or steam in the boiler. A simple ratio expressed as a percentage, thermal efficiency is basically the input energy transferred to the water or steam heating process divided by the output energy of the combustion process.
How Circulating Fluidized Bed Boilers Work? - Bright Hub
Circulating Fluidized Bed (CFB) combustion boilers gives the flexibility for combustion of a wide range of coals and alternative fuel sources. All this without compromising efficiency and with reduced emissions. This article gives a brief description of the working of a CFB boiler. At the bottom of the boiler furnace there is a bed of inert material.
Circulating Fluidized Bed Boiler | CFB Boiler | GE Power
EFFICIENT CIRCULATING FLUIDIZED BED BOILER COMBUSTION AND FUEL FLEXIBILITY. Our CFB boiler technology allows for a wide range of fuels to be burned efficiently. This includes low-grade and difficult-to-burn fuels such as anthracite, lignite, petroleum coke, oil shale, discarded coal, and biomass within a wide range of mixing rates.
Our CFB boilers are specially designed and optimized for applications to produce medium and high pressure steam or hot water with rated evaporation capacity from 35 to 440 tons/hr and rated pressure from 3.82 to 9.8 MPa. The CFB boiler design heat efficiency of CFB boilers is up to 87~90%.
