130t/h High Efficiency Thermal Power Plant Circulating Fluidized
Bed Boiler ASME and NB European Standard
The circulating fluidized bed (CFB) is a developing technology for
coal combustion to achieve lower emission of pollutants. By using
this technology, up to 95% of pollutants can be absorbed before
being emitted to the atmosphere.
1. Steel sheet separator cyclone and air-cooled(water cooled
2. Tail superheater area using air-cooled(water-cooled)wall
3. Rear fender economizer furnace wall: the guard plate frame light
furnace wall, boiler tightness.
4. Design of steel structures: Using finite element analysis
software of the boiler structure was accurately calculated to
ensure that the load distribution is reasonable.
5. Optimizing a secondary air ratio can be reduced auxiliary power,
strengthening extension to extend the disturbance in the furnace
flue gas residence time, improve thermal efficiency of the boiler.
6. Furnace section play, smoke long residence time in the furnace,
the furnace, the furnace up speed is low, the furnace circulating
volume, improve the boiler burnout rate, colleagues, greatly
reducing the wear of the furnace water wall region.
