Coal Boilers of 4-12 T/H Circulating Fluidized Bed Steam Boiler for Industrial Use (CFB)

 CHARACTERISTICS
- High efficiency: combustion efficiency 96~99%, carbon content in ash only about 2%, efficiency of boiler reaches 85%.
- Suitable for various kinds of coal.
- Load can be adjusted in the range of 25%~110%, average 5% in one minute.
- Clean combustion and environment friendly.
- Use lime stone mixed into the fuel for desulfuration, rate up to 84%.
- NOx emission capacity can be controlled to 150ppm or less.
- Ash with low carbon content can be used for cement or construction materials.
