 Various kinds fuel / High efficiency SFG Steam boiler insulation  

 

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. 

 

Features:

 

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
