0TPH CFB Boiler is another popular coal CFB boiler model in China besides 75TPH CFB Boiler. CFB boiler is suitable for burning coal, wood chip, bagasse, straw, palm husk, rice husk and other biomass fuel. Power plant boiler manufacturer Taishan Group won a 90TPH CFB Boiler three months ago and now it is under erection. The coal CFB boiler is high-temperature and high-pressure coal boiler. The client once purchased two 35TPH Coal CFB Boilers from us, and they have been operating smoothly for five years.

Features of the 90TPH CFB Boiler

1. Wide fuel applicability: anthracite, soft coal, low-grade coal, industrial cinder and coal gangue;

2. High combustion efficiency: the fuel burnout rate is above 98%, separation effect is good, and fly ash loss is small;

3. Large load adjustment range: minimum load can be 25-30%, and load change rate per minute is 5-10% of full load;

4. Efficient desulfurization, low nitrogen oxide emission: desulfurization rate is over 90%, and dust emission concentration is low;

5. Long service life of buried pipe: low flue gas speed, easy to replace, and service life is over 5 years;

6. Comprehensive utilization of ash and slag; low-temperature combustion has good economy and high return on investment.

7. Compact structure, small space occupation, low steel consumption, and less initial investment.
