Primary air refers to the supply air used in thermal power plants to carry pulverized coal into the boiler. There are hot primary winds and cold primary winds. The hot primary air is used to ensure that the pulverized coal has a certain temperature when it enters the boiler, thereby improving energy utilization. The cold primary air is used to adjust the temperature of the hot primary air to ensure the maximum heat exchange rate effect. The pulverized coal carried by the primary air enters the furnace and is burned with oxygen by the secondary air.
The six channels of thermal power plants refer to the cold air duct, hot air duct, pulverizing duct, powder feeding duct, flue gas duct, and raw coal duct of the boiler.
Thermal power plant, referred to as thermal power plant, is a factory that uses coal, oil, and natural gas as fuel to produce electric energy. Its basic production process is: the fuel is burned in the boiler and heated water is turned into steam, and the chemical composition of the fuel is converted into steam. The energy is converted into thermal energy, the steam pressure drives the steam turbine to rotate, the thermal energy is converted into mechanical energy, and then the steam turbine drives the generator to rotate, converting the mechanical energy into electrical energy.
