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. Bed is where the coal or fuel spreads. Air

the development of oxy-CFB technology with carbon capture and storage (CCS). CFBC, as an alternative to pulverised coal combustion (PCC), uses a fluidised bed, an apparatus that mixes coal and air with a sorbent such as limestone during the combustion process, to facilitate more effective chemical reactions and heat transfer.
When 0.6 ≤ F u ≤ 40, moderate fouling can be observed, but when F u ≥ 40, very high fouling occurs in the CFB boiler. oxide analysis of two Polish coal (hard coal and lignite) ashes and two biomass (two specimens of straw) ashes is given in Table 16.5 (Rajczyk and Bednarek, 2011).
Coal CFB Boiler uses bed material (such as silica sand) to support the combustion of coal around 900°C to generate heat. Steam produced inside the combustor can be used for power generation in steam turbine. Coal CFB Boiler can suit varying particle size (1-10mm) and varying fuel quality (from anthracite to lignite, petroleum coke).
1.Manage the coal particle size properly. For example, many fuels are available for 75 ton CFB boiler, but the coal particle size is related to the coal content in slag of it. The best size of coal particle is no more than 13mm. The coal content in slag is ideal when only 70 to 80 percent of the coal is in the size …
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.
ZOZEN is one of the best modern boiler manufacturers in China. Our products have been sold to more than 100 countries and regions and set up offices in many countries to ensure that they serve customers at the first time.
