Boiler exhaust temperature
Smoke emission loss is the main reason that affects the operation efficiency of gas boiler, which is mainly affected by the amount of smoke emission and the excess air coefficient. By analyzing the combustion principle, it can be found that the larger the excess air coefficient is, the higher the amount of smoke emission will be, and naturally more heat will be taken away.How can gas boilers save energy and reduce consumption?
Gas boiler unit using need to focus on the heat pipe network, the old rock wool is rock wool glass cloth form to replace the outsourcing in the form of sheet metal, which lower the heat loss in the pipe network, improve the efficiency of the application of energy, strengthen the soft water tank insulation at the same time, improve the soft water tank insulation to reduce boiler softened water heat loss.
Equipment power consumption
Gas boiler will consume a lot of electric energy in operation. In order to reduce the electric consumption of boiler room, reasonable equipment configuration and advanced technology can be adopted to analyze the operation status of boiler room, fully understand the characteristics and performance of each equipment, and calculate the operating flow rate, power and efficiency of pumps and fans under the pipe network.
By reasonable allocation to develop best practices, and thus reduce the starting current to avoid excessive impact on power grid electricity, staff can use frequency converter to reduce the frequency of the alternating current (ac), at the same time adopt inverter, such as adopting fan frequency converter to change the fan speed, improve the boiler of the closed loop control system, realize the constant power, constant voltage, and reduce the energy consumption of the boiler, improve the comprehensive benefit.
The boiler blowdown
It is possible to reduce the heat loss through regular sewage discharge, and at the same time, check the water quality of the gas boiler regularly, so as to ensure that the water supply quality of the boiler conforms to the standard, and master the water alkalinity of the gas boiler and its changing rules under the condition of high pressure and low load.
By correctly and reasonably discharging the impurities, mud and scale in the boiler water, controlling the alkalinity and salt content of the boiler water, making the boiler water quality meet the national standards, ensuring the cleaning of the heating surface, meeting the qualified steam quality requirements, extending the service life of the boiler, making full use of the waste heat of sewage, and achieving the effect of energy saving.
