Automatic control system for shock blowing is an effective removal of large boiler air preheater, economizer, superheater and furnace heat exchanger surface area of ash new technology.
    During operation of the boiler, heat exchanger fouling on the surface will be weakened resulting refrigerant and heat exchange between the flue gas to increase the flue gas resistance, reduce the boiler thermal efficiency, increase fuel consumption and affect the normal operation of the boiler. In industrial boilers, fouling caused by the rear heat exchanger sometimes corrosive, causing the boiler to run risks. And medium-sized boilers are now running essentially installed the different types of blowing devices, such as, steam ash, water ash, steel ball ash, such as acoustic or ultrasonic soot cleaning. However, these different problems common ash removal equipment.
    Automatic soot blower control system has a high shock energy, enough to produce fouling layer of broken shock, while the blowing has a good effect, and its low running costs, simple operation, safe and reliable. Automatic soot blowing control system is the shock wave pulse through the gas deflagration of compression wave is generated. Fuels (acetylene, natural gas or propane gas fuels high reactivity) in a special high-energy ignition device has been ignited, resulting in severe deflagration flame-fung, so that the burning of gas moments after the rise to high pressure, and in front of the flame-fung, the formation of compression wave ; in through the flame tube, the compression wave continuously strengthened, and the formation of a stable shock wave; this Road after the shock wave into the shock wave generator, on the one hand as the shock wave ignition of combustible gas ignited tank, on the other shock in special the structure of shock occurs while the tank is modulated to enhance the final shock wave modulation a good spray from the nozzle to the boiler heat transfer equipment, so that heat the surface of the role of fouling by the shock wave breaking, peeling. By controlling the energy shock, forcing heating surface fouling in the shock wave under the action of sufficient strength to fall off to accommodate the boiler heating surface of the different types of fouling.
