Gas pulse shock soot blower works by mixing air and flammable gas (such as acetylene, liquefied gas, hydrogen, etc.) in a special container in a proper proportion. After high-frequency ignition, it produces a deflagration, which instantly produces huge energy oscillation. The energy can be a shock wave that hits and sweeps the surfaces of the tube bundle. This action can lead to the surface areas’ ash flying, then the wave can carry the smoke away.
According to the setting position of the gas mixing point, it generally can be divided into two types: theserial type and the parallel type. The tandem system means that the gas mixing point is arranged on the main pipeline;whereas the parallel system means that the gas mixing point is arranged on the branch pipeline of each soot blowing. Thus, after turning on the igniter,the high temperature gas is generated and directly transferred to each soot blowing. In terms of system settings, the parallel type is more secure and more flexible than the series system.
The gas pulse shock soot blower is mainly composed of a gas supply system, a main air supply system, a gas mixing tank, an igniter, a shock energy distribution system, a shock generator and shock tube, etc.
