CFB boiler can burn various fuels, such as soft coal, anthracite coal, lean coal, lignite, gangue, sludge, petroleum coke and biomass (wood chip, bagasse, straw, palm husk, rice husk, etc.) Our CFB boilers are specially designed and optimized for applications to produce medium and high pressure steam or hot water with rated evaporation capacity
In all of the CFBs of this study, one or more “jets” of high speed gas were observed at any time in the CFB risers. APPLICATION OF HIGH-LOW BED CFB COMBUSTION . Application of High-Low Bed CFB Combustion Technology to Oil Shale Combustion 151 Fig. 2. Schematic structure of the 75 t/h pulverized coal-fired boiler. 4.
CFB uses coal crushed to sizes of around 3 to 6 mm. The time energy and facility required to crush coal is much lesser than pulverizing coal. PC firing uses around 30 % of the combustion air as high pressure primary air for drying and transporting fuel. CFB uses higher pressure primary air which is 60 % of the combustion air for fluidizing.
Coal Fired Steam Boiler - yd-boiler.com. 2019-8-19 · Coal-fired boilers have lower operating costs – nearly 50% lower than gas/oil fired boiler. our coal-fired boilers have the advantages of sufficient output, high thermal efficiency and wide coal adaptability without compromising safety and reliability.
This boiler is a new type CFB boiler, which designed and optimized on basis of JBG 420 t/h coal fired CFB boilers, with high efficiency and low China CFB (Circulating Fluidized Bed Boiler 15-50t/h China CFB (Circulating Fluidized Bed Boiler 15-50t/h), Find details about China Steam Boiler, Boiler from CFB (Circulating Fluidized Bed Boiler 15
However, CFB boilers have also shown deficiencies, such as high coal particles, a decrease in bed pressure drop yields an increase in bed . Ask Price View More; Valmet CFB Boiler utilizes circulating fluidized bed technology. Valmet CFB Boiler (formerly known as CYMIC) is an advanced circulating fluidized bed (CFB) boiler developed by Valmet.
Our DZL series coal fired boilers are specially designed and optimized for applications to produce high pressure steam or hot water with rated evaporation capacity from 1 to 45 tons/hr and rated pressure from 0.7 to 1.6 MPa. The design heat efficiency of DZL coal boilers is up to 81~82%.
GE’s Boilers portfolio addresses all fuels with pulverized coal (PC) boilers that can burn a wide range of hard coals, lignite, and oil/gas, and Circulating Fluidized Bed (CFB) for both conventional and difficult to burn fuels.

Ultra-Supercritical Circulating Fluidized Bed (CFB) Boilers. 660 MWe for lignite B, higher for hard coal, for low-grade and difficult-to-burn fuels such as anthracite, lignite, petroleum coke, oil shale, discarded coal and biomass, GE offer circulating fluidized bed technologies with different arrangements suited to …
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.
Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.
