Function
1. Filling of Dosing Tanks
After release by the programmable logic control the solenoid valves of the gas supply and the dosing tanks are opened, and the dosing tanks are filled with Oxygen and Natural Gas until the setting pressure is reached. Afterwards, the solenoid valves are closed again. The two gases are completely separated from each other and therefore not explosive.

2. Transfer and Mixing
The transfer solenoid valves for Oxygen and Natural Gas are opened. The two gases flow into the explosion tanks and are mixed. Afterwards, the solenoid valves are closed again. The piston is pressed against the discharge opening by the Nitrogen pressure and closes it gastight.

3. Explosion and Injection of Pressure Wave into the Plant
The spark plug is activated and ignites the explosive mixture of gas. The pressure rise in the explosion chamber of the EG10 to 350 bar makes the piston move backward, whereby the discharge opening is opened. The pressure wave is transmitted into the plant through the connection pipe. The pressure wave makes slag and ash deposits break off and puts walls and bundles into short vibrations, which further enhances the cleaning efficiency. After the pressure wave was ejected, the piston is pressed again to the discharge opening by the Nitrogen and completely closes the discharge opening. The Explosion Generator is ready for the next explosion.
