Exchange arrangement for heat produced by gas combustion.

摘要

The arrangement comprises a heater (18) with a condensation cavity (20); a boiler (2) with an evaporator (10); an outgoing and return communication circuit (24) between the evaporator (10) and each cavity (20) and a thermal fluid which may be vaporized in the evaporator (10) and which is condensable in the condensation cavities (20). In the evaporator (10), the circuit (24) and the cavities (20), further to the vaporizable fluid, there is a gas which is non-condensable at room temperature, preferably an inert gas and there is a chamber (38) for non-condensable gas and lines (40) for communicating the cavity (20) with the non-condensable gas chamber (38). <IMAGE>
