Analysis of Coal-fired Boiler Operation
Introduction
The coal-fired boiler is a large industrial boiler widely used in all walks of life. As an important energy source, the correct operation and maintenance of the coal-fired boiler can not only reduce the thermal energy consumption, but also reduce the environmental pollution. In the understanding of the technology of the coal-fired boiler, the operation and maintenance will become more scientific and reasonable.
Working Principle of coal-fired boiler
The working principle of the coal-fired boiler is similar to that of the steam boiler. It is composed of a furnace, a furnace wall, a furnace roof, a furnace fire door, an inner combustion chamber, a smoke pipe, a smoke box and other components. When the boiler is in operation, the coal is burned in the combustion chamber, and the hot air generated by the burning enters the furnace and radiates through the furnace wall to the heating surface. The high temperature smoke enters thesmoke box, and the heat is taken away by the flue gas convection radiation to the atmosphere and discharged through the chimney. Through the hot air circulation, a continuous coal-burning process can be achieved.
Features of coal-fired boiler operation
1. Boiler water level control: Water level plays an important role in the safe operation and control of coal-fired boiler. According to the design requirements of the water level, the water level should be kept within the specified range, and the water level should be kept stable.
2. Boiler pressure control: The safe operation of coal-fired boilers needs to pay attention to the boiler pressure. When the pressure is too high, the exhaust valve should be opened for exhaust; when the pressure is too low, the boiler should be opened for supplementary water.
3. Boiler Safety Protection Settings: In order to ensure the safe operation of coal-fired boilers, all kinds of safety accessories need to be installed in the operating boiler.
Maintenance of coal-fired boiler
1. Establish an operation file: Establish a filing system for boiler operation instructions, boiler equipment operation records and maintenance records to ensure the safety information of the boiler.
2. Clean the boiler regularly:Regular cleaning of the furnace, smoke pipe and burner and other components of the boiler is essential.
3. Regularly check the wear of the boiler: A regular check of the wear degree of the boiler component is necessary to ensure that the component is operating safely.
Conclusion
Although the operation of coal-fired boiler is very important, its operation and maintenance should be done properly. In addition, regular maintenance of the boiler is necessary, which can not only ensure the safety of the coal-fired boiler, but also increase the service life of the boiler.
