Therefore, it is necessary to remove the ash accumulation. Currently, pulse soot blower ash removal is a new generation of ash removal technology. It uses acetylene to burn in a specially designed combustion chamber and emits shock waves from the nozzle on the output pipe. The shock wave is used to remove the ash on the heating surface.
