How to Improve the Thermal Efficiency of Boiler?
2021 / 11 / June
Reduce the heat loss of boiler exhaust
- Lower the air leakage rate of the air preheater, especially the air leakage rate of rotary air preheater.
- Strict control of boiler pot water quality objectives, when the water-cooled wall tube scale content reaches 400mg / m, should be promptly acid cleaning.
- Try to burn high quality fuel with low sulfur content, lower the air preheater inlet air temperature, ancient large-capacity power boilers are equipped with air preheater, to avoid condensation on the cold front of the air preheater heating surface, resulting in high-temperature corrosion of the air preheater.
Reduce mechanical incomplete extinguishing heat loss
- According to the boiler load and work to adjust the quenching conditions, reasonable air distribution, so that the fuel in the furnace chamber to quench.
- According to the fuel volatile fraction and work to adjust the amount of feed, so that the amount of fuel to maintain the appropriate.
- Reduce the heat loss of the boiler, secondary to enhance the maintenance and overhaul of the boiler piping and insulation layer of the body.
