As you know, the thermal efficiency of high quality gas boiler is the heat generated when the fuel is extinguished and it is transferred to the water in the boiler. The heat transfer effect is the thermal efficiency. The higher the thermal efficiency, the better the heat transfer function. Gas-fired boilers have an efficiency of 90-99%, while coal-fired boilers have a thermal efficiency of 85% or more.
The efficiency of a gas boiler is an important target for clarifying the economic function of the boiler. A high thermal efficiency indicates that the boiler is economical and that the waste of fuel reduces the primary power consumption. Improving the boiler thermal efficiency means increasing the inefficient applied heat and increasing the heat loss of the boiler, which focuses on reducing the exhaust heat loss and mechanical incomplete extinguishment loss of the boiler.
Reduce the exhaust heat loss of high quality gas boiler is mainly to reduce the air leakage rate of high-altitude preheater, especially the air leakage rate of rotary air preheater. Strict control of boiler water quality indicators, when the water-cooled wall tube scale content reaches 400mg / m, should be timely acid cleaning. Try to use high-quality fuel, reduce the air temperature at the entrance of the air preheater, to avoid condensation on the cold end of the air preheater heating surface, resulting in high-temperature corrosion of the air preheater.
Industrial gas boilers have high thermal efficiency and high energy efficiency. At present, energy-efficient boilers are also energy-saving and environmentally friendly boilers. Saving energy means reducing energy consumption. Energy consumption can be reduced because the boiler is highly efficient. As long as the boiler is efficient, the result must be environmentally friendly. In this way, it can be seen that energy saving, environmental protection and high efficiency are even equivalent, because they all represent the advantages of the product. However, we should know that although a considerable number of manufacturers in the boiler industry have been eliminated from the competition for energy-efficient boilers, the main reason is that the level of technology does not achieve a certain level of energy efficiency. The remaining manufacturers will also have significant differences, which can be directly reflected in the measured energy efficiency of the product.
In general, the efficiency of a gas boiler is the higher the thermal efficiency of the boiler, the lower the gas consumption. ZOZEN Boiler produces energy-saving and environmentally friendly boiler solutions for many customers, welcome to consult and purchase, we will be happy to serve you.
