Supersonic pressure waves are generated with compressed air — no pure oxygen. These pressure waves are also called “power waves”, “shock waves” or “shock pulse”.
Fully automatic
An alternative to manual explosion cleaning. P-Wave generators operate fully automatically and integrate into existing plant control systems. Overcome the safety and cost limitations of manual explosion cleaning systems.
Combustion without detonation of explosives
The supersonic pressure waves are created when super-high-pressure gas is released very quickly from the generator into the boiler. The initial energy comes from burning small amounts of propane (~20 g/shot) mixed with compressed air in the process chamber. The expansion of the combustion gas is a separate process step independent of the combustion.
Adjustable pressure & power
Combustion pressures are typically set between 150 and 600 bar. The generator is designed and certified for 900 bar. Operators can program timing and strength, so cleaning is tuned to actual site requirements.
The effect of supersonic pressure waves
Reflection effect
Pressure waves strike the heating surface and reflect, shearing deposits off the windward face.
Fouling / slag
Vibration effect
The waves set the tube vibrating, so brittle deposits crack and fall away on every side.
