How to improve boiler net efficiency?

It can be known from the concept of boiler net efficiency. To improve the net efficiency of the boiler, it is necessary to not only improve the thermal efficiency of the boiler, but also reduce the boiler's own energy consumption (heat and electricity). The amount of steam consumed by the boiler includes the amount of steam consumed by the auxiliary steam soot blowing steam heater, etc. If the waste heat cannot be recovered, it will also be part of the energy consumed. Therefore, it is necessary to reduce self-consumption steam and recover other waste heat. The electric energy consumed by the boiler includes the power consumption of auxiliary equipment such as supply and suction fans, primary fans, pulverizing systems or oil pumps. For this reason, sufficient attention should be paid to the following main factors that affect the power consumption of the factory.: (1) While ensuring combustion, try to reduce the excess air coefficient and reduce the resistance of the flue duct and burner, thereby reducing the power consumption of the fan. (2) Reduce the power and steam consumption of the water supply pump as much as possible, use the water supply pump rationally to improve the operation mode, and reduce the resistance of the water supply pipeline. (3) Strive to improve the efficiency of the fan and water supply pump.
