Environment friendly CFB boiler/circulating fluidized bed boiler 2015 new designed steam boiler 

Efficiently desulphurization, burn at low temperature, Nox(nitrogen oxide) exhausts low .Fuel pretreatment system is simple.

Wide burnable suitability, suitable for both high-quality coal and the inferior coal.
High Combustion efficiency, Gas-solid mixing good, the big granule fuels can recycle in furnace again until well combustion.

Introduction of Yongxing CFB boiler/circulating fluidized bed boiler :
Circulating fluidized bed boiler is a new efficient, low-pollution technology of clean coal boiler, the main features of the boiler furnace with a lot of material, in the combustion flue gas in a large number of materials are carried to the upper chamber, through the arrangement In the separator furnace exit, the materials and gas separation, and after non-mechanical valve will be sent back to materials will be sent to bed, repeatedly looping combustion. Because high concentrations of materials and has great heat capacity and sound materials Hunhe generally carry a number of per kg of flue gas Ke kilograms of materials are Xunhuan brings high heat transfer material coefficient in the boiler heat load regulation, wide range of the fuel adaptability. Circulating fluidized bed boiler higher than the bubbling fluidized bed speed, rather than the bubble column as a clear interface, due to strong turbulence and bed material circulation, increased fuel residence time in the furnace, Therefore, higher than the bubbling bed combustion efficiency, stable under low load operation, no additional auxiliary fuel. Circulating fluidized bed boiler operating temperature is usually between 850 ~ 900 °C is an ideal desulfurization temperature range, using furnace desulfurization technology by adding limestone to the bed as a desulfurization agent, fuel and desulfurizing agent after repeated cycle of repeated low-temperature combustion and desulfurization reaction, coupled with intense turbulent furnace, Ca / S molar ratio of about 2:00, you can make about 90% desulfurization efficiency, SO2 emissions is greatly reduced. At the same time adopting a classification air circulating fluidized bed combustion, the combustion is always carried out at low excess air, which greatly reduces the formation and emission of NOX. CFB boiler also has a high combustion efficiency, can be fueled with low-grade fuel, the boiler load regulation is good, ash comprehensive utilization of the advantages of easy, so the world has been growing rapidly. With the increasingly strict environmental protection requirements, generally considered, circulating fluidized bed is the most practical and feasible and efficient low-pollution coal-fired one device.

Featuresof Yongxing CFB boiler/circulating fluidized bed boiler :

1. Fuel adaptability to meet the multi-fuel combustion.
2. A high degree of automation, in the long term to keep the boiler safe and economic operation.
3. Boiler combustion efficiency as high as 95% to 99%, fuel efficiency, the boiler thermal efficiency up to 87%, and energy-saving and efficient.
4. Using exhaust high temperature cyclone separator, the collection of bed material high furnace heat transfer coefficient high overload ability.
5. Boiler load adjustment range, can be 110% to 30% range of adjustment, especially for a large range of boiler load fluctuations occasion.
6. Bed compound can be added limestone, combustion and flue gas SO2 in the reaction of sulfate, desulfurization to meet environmental requirements, while the lower furnace combustion temperature can inhibit the formation of NOX, truly environmentally friendly combustion.
