Circulating fluidized bed biomass power plant boiler is a thermal energy equipment which adopts circulating fluidized bed technology. The heat of the circulating fluidized bed biomass boiler produced is mainly used to power generation, large-scale heating system. The fuel burnout is not easy after slagging, and reduce the NOx, SOx and other harmful gas generation, which is with significant economic and environmental benefits.
Circulating fluidized bed biomass power station boiler furnace has large combustion space, so that fuel in the furnace has sufficient time to burn, while a certain degree of furnace in the layout of a high enough layers of secondary air to meet a large number of volatile concentrate release combustion, to ensure that combustibles combustion with the air fully mixed, so that combustible materials can burn in the hearth. The type of boiler in the furnace layout of the superheater as a high-temperature superheater, a fundamental to avoid the high-temperature superheater fouling, eliminating the high-temperature superheater caused by high-temperature corrosion of one of the incentives.
Circulating Fluidized Bed Biomass Power Station Boiler Features
1. Power Saving
The low bed pressure operation of the circulating fluidized bed biomass power station boiler, the primary and secondary blower of the boiler, the pressure head of the Roots blower and the induced draft fan are reduced, the power consumption of the fan is reduced and the power saving reaches over 30%.
Low bed pressure operation, reduced backpressure in the furnace, lower concentration of material in the secondary air region, enhanced effect of secondary air penetration perturbation, improved combustion efficiency, and 3 to 5% of boiler coal and biomass savings.
3. Low Wear
Heating surface almost no wear and tear, the annual operating hours up to 8000 hours or more.
4. Low resistance
After a new generation of ultra-efficient technology to improve cyclone, d50 value of 12 microns, d99 value of 100 microns. Separation efficiency of more than 99.6%, the total resistance of less than 1100pa.
