PCT No. PCT/AT86/00045 Sec. 371 Date Feb. 4, 1987 Sec. 102(e) Date Feb. 4, 1987 PCT Filed Jun. 4, 1986 PCT Pub. No. WO86/07435 PCT Pub. Date Dec. 18, 1986.In a heat exchange container (1) that is preferably water filled and used in a space or central-heating system a furnace system having a combustion chamber (5) for the pulse combustion of free-flowing, in particular, liquid fuels is used, and this is mounted as a container insert on a carrier plate (2) that closes an opening in the container (1). The air supply takes place intermittently through valves (30) and the fuel supply is continuous and under pressure, through an axially adjustable injection nozzle (29) into a prechamber (10) so that the injection pressure and the position of the injection nozzle (29) constitute important adjustment values. Close to the base of the combustion chamber within the prechamber (10) there is a vortexing element that vortexes the fuel-air mixture that is formed, doing so on the combustion chamber side, the opening cross-section of this vortexing element being adjustable. This, too, constitutes an additional control variable. The combustion chamber (5) is preferably configured so as to be contained in a double jacket, in which connection the double jacket includes a very narrow gap that permits thermal transfer, whereas the double combustion chamber base has a broad, thermal insulating gap.
