What are the reasons for insufficient combustion of coal-fired boilers?

There are many factors that affect the operating cost of the boiler, among which the insufficient combustion of the coal-fired boiler directly leads to an increase in the cost of the boiler. Therefore, users should adjust in time during daily operation and use to avoid insufficient combustion of coal-fired boilers.

Causes and treatment of insufficient combustion of coal-fired boiler

1, Insufficient air volume; Need to increase the air intake,

2, poor ventilation, insufficient oxygen supply, so that coal can not be fully burned; Increase ventilation,

3, the fire temperature is too low, did not reach the ignition point of coal, so that the coal can not be fully burned; Change the nature of fuel and adopt high volatile coal;

4, The coal is too big, and it is sent out without being fully burned in the furnace of the boiler. Choose the appropriate size of coal;

5, The coal is unevenly distributed in the furnace, causing partial furnace and slagging. When cutting, the feeder can be increased to evenly cut.

Wuxi ZOZEN Boiler Co., Ltd. has been designing and manufacturing coal-fired boilers since its establishment, with mature technology and projects in many countries and regions around the world. At present, ZOZEN coal-fired boilers cover DZL, SZL, DHL, SHL, DHX, QXX and other series. The internal structure of the boiler is reasonably designed, the fuel is fully burned, and the heating surface is sufficient. The thermal efficiency of the coal-fired circulating fluidized bed boiler is as high as 89%.

With the accumulation of more than 30 years of manufacturing boilers, ZOZEN boilers have formed gas-fired boilers, biomass boilers, coal-fired boilers, heat transfer oil boilers, circulating fluidized bed boilers and other varieties and specifications, and are widely used in chemical industry, food, winemaking, etc., heating, papermaking, printing and dyeing, rubber and other industries. At the same time, ZOZEN Boiler has also established a four-full service system, including the whole-process installation guidance, 72-hour accompanying operation, customized boiler room and other services, and will provide technical guidance in time for the problem of insufficient combustion of coal-fired boilers.
