Product Description

The basic overview of energy-saving circulating fluidized bed boiler
Energy-saving fluidized bed takes the principle of stationary design and circulating fludized bed map as the guide, the theory of material balance and the theory of particle fuel combustion and a more substantial reduction in the total bed stock, thus the flow pattern based on the re-structure of energy-efficient circulating fludized bed boiler technology. It represents the latest development direction of the circulating fluidized bed technology.
Based on the flow reconstruction of energy-saving circulating fluidized bed combustion technology, has overcome the difficulties of high power consumption and wear of circulating fluidized bed boiler plant. Power can be reduced by 30% at least, at the same time, the reduction of wear and tear of the boiler can increase the using rate of boiler, and the maintenance costs can be reduced accordingly.
The structure features of energy-saving circulating fluidized bed boiler.
1. Single horizontal drum, "π" type layout.
2. The suspension furnace equipped with film water -cooled wall and the imports separator is water-cooled flue.
3. The bell-type air cap is easy to replace, low resistance and non-inverted gay.
4. The separator and the center tube have the technological improvements for low resistance, high separation efficiency.
5. The use of patent technology and equipment with the independent device of Roots blower to save power consumption
6. Low bed pressure operation
7.Primary air fan is used at a lower pressure, reducing the fans power consumption
8. Optimization of the secondary air and the floe vents to reduce the secondary fans air pressure.
9.Improved fuel crushing and screening system, the size of fuel particle is in line with the designed requirements
10. The air preheater uses a multi-tube box arrangement and low-temperature section uses corrosion-resistant steel to avoid the whole part replacement duo to the low-temperature corrosion.
The performance characteristics of energy-saving circulating fluidized bed boiler.
1.Power saving: the fan can save 30% or more power
Power consumption, operate under low bed pressure, the pressure head of the first, second blower,roots blower,induced draft fan have been reduced, the power consumption of fans is reduced.
2.Fuel-saving: This fuel-saving of boiler can reach 3-5%.
Operate under low bed pressure, back-pressure reduced in the furnace, reduce the concentration of secondary air regional materials, the effect of secondary air penetration disturbance is enhanced tp improve combustion efficiency.
3. Low wear: There is almost no wear and tear on the heating surface and the annual operating time is up to 8000 hours.
4. Low resistance, will not be brought down gray of bell-type hood.
The Bell hood using of unique anti-wear technology, even wind and small resistance
