yassa I think this is a good solution as any!
After the exhaust fumes go out of the chamber, rather than squirting more gas into the boiler chamber, it injects ordinary water inside the extremely hot chamber, the water immediately turns to steam� expanding to 1600 times its volume� which forces the steam down for a second time; this is known as secondary heat extraction.
Another cycle pushes the steam out of the chamber, and out of the extractor .thus creating a fog horn sound in the trade this is known as the clear fog horn sound. The only solution is a heavy water supply when the heavy water exits the system thus creating heavy steam this drops on the ground and rolls around, this is known as the heavy water cymbal sound this is often preferred to the fog horn sound because of its musical qualities.
