Abstract

In view of the problems of ash clogging and corrosion existing during long period on the rotary air preheaters

retrofit of the original steam shootblowers has been carried out by using the fuelgas impulse type shootblowing technology. The said technology adopts intelligent control for mixing ratio and concentration of fuelgas and air

utilizing the high energy impulse wave generated from explosive burning of acetylene gas to clean and blow the ash deposits on the heat transfer components. The operation practice of more than one year shows that the said impulse type shootblowing technology can effectively remove ash deposits from the rotary air preheater

lengthening the servicelife of matrix elecments in the said air preheater

enhancing the heat transfer efficiency and utilization coefficient of the said air preheater

having remarkable economic benefits.
