What is a power plant boiler?

Apr 21,2025

  Power plant boilers are the core equipment of thermal power plants.

  Power plant boilers, also known as power plant boilers, are large boilers used for power generation in power plants. They mainly convert the heat generated by efficient combustion of fuels (such as coal, oil, and natural gas) into steam, which in turn drives the turbine to rotate and drive the generator to generate electricity. Power plant boilers generally have a large capacity, with the main units reaching 600MW, while more advanced ultra-supercritical boilers have a capacity as high as 1000MW.

  Power plant boilers are mainly composed of a combustion system, a steam-water system, a control system, and an auxiliary system. The combustion system includes the furnace and burner, used for fuel combustion and heat release; the steam-water system includes economizers, evaporative heating surfaces, and superheaters, responsible for water heating, evaporation, and steam superheating. The control system uses various instruments and automatic control devices to monitor and adjust the boiler to ensure stable operation. The auxiliary system includes soot blowing, slag removal, and water treatment equipment, used for the normal operation and maintenance of the boiler.

  There are various types of power plant boilers, such as pulverized coal boilers and circulating fluidized bed boilers, each with its unique application advantages and technical characteristics. In addition, power plant boilers are also equipped with a series of environmental protection equipment, such as dust collectors, desulfurization systems, and denitrification devices, to reduce pollutant emissions in flue gas and ensure compliance with environmental standards.

  In summary, power plant boilers are indispensable equipment in thermal power plants, and their efficient and stable operation is of great significance to ensuring power supply and promoting economic development.
