Background

The coal-fired boiler is coal burned by fuel, after the heat of the coal is converted, steam is generated or the steam is changed into hot water, air required by coal powder combustion in a hearth of the coal-fired boiler can be used for auxiliary heating and drying of the coal powder, and the coal powder is conveyed to a burner nozzle from a coal mill outlet. Because of the explosion-proof requirement of the coal mill, the temperature of the air powder at the outlet of the coal mill is generally limited to 70-100 ℃. The air-powder temperature is too low, so that incomplete combustion of coal powder is increased, ignition heat required by the coal powder is increased, and coal consumption and low-load stable combustion capability of a unit are seriously affected.

With the adjustment of the electric power structure in China, the annual utilization hours of thermal power equipment are reduced continuously, and the time of participation of the thermal power generating unit in deep peak regulation and low-load operation is continuously prolonged. When the boiler runs under low load, the average temperature of the hearth is reduced, the ignition time of the pulverized coal is prolonged, and the stable combustion performance is reduced. Air-powder flow equalization is needed, combustion efficiency is improved, and the combustion of coal powder can reach the expectations of people.
