High-pressure hot-water cleaning machine using liquid gas, natural gas or town gas

摘要

The invention relates to a high-pressure hot-water cleaning machine using liquid gas, natural gas or town gas. Said cleaning machine has basically a water circuit, into which low-pressure water flows, which is heated and subsequently supplied to a pump, out of which high-pressure water flows, which is conveyed to a jet pipe. The water is heated by a boiler which has a pipe coil which is in its entirety subject to the direct action of a flame which flows from a burner with gas-firing. IMAGE
