The thermal efficiency of an industrial boiler is an important indicator for measuring the economic performance of the boiler. In simple terms, the higher the thermal efficiency of the boiler, the higher the economy, and the waste of fuel reduces the primary power consumption. How to improve the thermal efficiency of industrial boilers, or buy an industrial boiler with high thermal efficiency, has become the focus of manufacturing enterprises.
Regarding the thermal efficiency of industrial boilers, the boiler has design efficiency at the engineer design stage. Generally speaking, the actual operation is similar to the initial design thermal efficiency. For example, the efficiency of oil and gas furnaces is greater than 92%, and the efficiency of circulating fluidized bed boilers is usually higher than 88%. However, the boiler efficiency is not fixed. If your equipment is operating at a rate lower than the design efficiency, then measures can be taken to improve the boiler thermal efficiency.
Improving the thermal efficiency of industrial boilers can increase the various heat losses of the boiler by adding ineffective application heat, the focus of which is to reduce the boiler exhaust heat loss and the loss of machinery not completely extinguished. Zhengzhou Fangkuai Boiler Company will briefly explain some specific operation methods for everyone.
1.Reduce boiler exhaust heat loss
(1) Reduce the air leakage rate of the air preheater, especially the air leakage rate of the rotary air preheater;
(2) Strictly control the water quality target of boiler water. When the scale in the water-cooled wall tube reaches 400mg / m, it should be pickled in time;
(3) Burn high-quality fuel with low sulfur content as much as possible and lower the air temperature at the inlet of the air preheater. The ancient large-capacity power generation boilers were equipped with air preheaters to avoid condensation on the heating surface of the cold front end of the air preheater. Incurred high temperature corrosion of the air preheater.
2.Reduce the heat loss caused by mechanical failure
(1) Adjust the extinguishing conditions according to the boiler load and time, and reasonably distribute the air so that the fuel is fully extinguished in the furnace;
(2) Adjust the feeding amount according to the fuel volatile content and time to maintain the optimal amount of fuel.
3. To reduce the heat loss of the boiler, not only the thermal insulation measures of the boiler itself must be in place, but also the maintenance and repair of the boiler pipes and the thermal insulation layer of the boiler must be enhanced.
