Boiler body uses the forced circulation in the high temperature area to make sure all heating areas can be cooled down and avoid vaporization; The explosion door and flame detector are equipped for safe and reliable operation.
Ways to Calculate CFB Boiler Efficiency
Combustion efficiency measures how effectively a CFB boilertransfers the chemical energy stored in fuel into usable heat. Reaching optimum combustion efficiency typically requires pumping additional air into the combustion chamber so that all fuel can be burned.
Circulating Fluidized Bed Boiler | CFB Boiler | GE Power
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. Low inherent NOx emissions at 50-200 mg/Nm3
Combustion Efficiency and Excess Air - Engineering ToolBox
Carbon dioxide - CO 2 - is a combustion product and the content of CO 2 in a flue gas is an important indication of the combustion efficiency. Optimal content of carbon dioxide - CO 2 - after combustion is approximately 10% for natural gas and approximately 13% for lighter oils.
Fluidized Bed Boiler - an overview | ScienceDirect Topics
The excess air coefficient at the furnace exit of a typical CFB boiler is 1.2, and the sectional superficial gas velocity is 5∼6 m/s at 850°C, so the furnace cross section heat release rate is 3.6∼4.4 MW/m 2.

Circulating Fluidized Bed (CFB) Boiler capacity: for CFB steam boiler upto 250 ton, CFB hot water boiler upto 170MW. CFB boilers offer benefits such as low pollution, high-efficiency combustion, space saving, and high maintainability. ZG's CFB Boiler technology is expected to be at the forefront of next-generation environmentally conscious boilers.
Comparison of Circulating Fluidized Bed Boiler and
In CFB boilers the collection at the bottom is almost 50 % lessening the load on the Electroststic Precipitators. The water and steam circuit, the natural circulation of water and heat transfer surfaces are all the same in both the systems. The diagrams below indicate the overall difference between the CFB boiler and the PC boiler systems.
correction factor of cfb boiler efficiency – CFBC Boiler
Although little data concerning the operation of CFB boiler is available, the main goal of the modeling is to predict the influence of biomass gasification gas on boiler efficiency and exhaust gas temperature [19,20]. Some operation instructions of the 300 MW CFB …
ACHIEVABLE COMBUSTION EFFICIENCY with ALSTOM CFB …
Abstract: The key driver for choosing a Circulating Fluidized Bed (CFB) Boiler is the ability to burn a wide range of fuels with highly efficient combustion while meeting low emission requirements. Reduced sorbent and water consumption compared with Pulverized Coal (PC) plants and the ability to
Valmet CFB Boiler utilizes circulating fluidized bed
Valmet CFB Boiler (formerly CYMIC) is an advanced circulating fluidized bed (CFB) boiler developed by Valmet. It combines high-efficiency combustion of various solid fuels with low emissions, even when burning fuels with completely different calorific values at the same time. The wide size range covers boilers from 30 to 1200 MWth.
