HEATING SYSTEM ALLOWING STEAM ENRICHMENT OF COMBUSTION AIR BEING FED TO A HEAT SOURCE

摘要

1. Heating system comprising a gas burner (11) housed in a heating enclosure (2) comprising at least one combustion air inlet (7) and an outlet (8) for the burnt gases coming from the enclosure (2), characterized in that the enclosure (2) contains a separator (3) consisting of a plurality of membranes (4a-4f) which extend in parallel and vertical relationship within the said enclosure and which define between them a series of passage-ways (14a) for the burnt gases issuing from the enclosure and another series of passage-ways (15) for the combustion air within the said separator and in that the said membranes are semipermeable and provide for the passage of the steam of the burnt gases in the combustion air which flows in counter-current relationship with the burnt gases within the said separator.
