This central heating apparatus for oil burner and boiler systems comprises a detachable structure disposed in the boiler furnace between the burner and the boiler; the structure comprises essentially a base frame supporting a vertical upright rigidly welded thereto and to which an assembly of stacked elements are secured by means of a common and single belt substantially aligned with the burner; this assembly comprises a pyramidal front member facing the burner, followed by a fan-like assembly of radial blades and, bearing against the upright, a perforated plate of which the holes are so punched that their material forms protruding fins directed towards the burner flame and adapted to become white hot in order to improve the combustion and eliminate soot deposits and the release of excess smoke.
In a central heating apparatus comprising a boiler having walls defining a combustion chamber, a burner nozzle projecting a flame into the combustion chamber toward an opposite wall thereof, and a flame-permeable structure interposed between the nozzle and said opposite wall, the improvement that said flame-permeable structure comprises at least one flame-resistant sheet metal plate disposed in a plane approximately perpendicular to the direction of projection of said flame and having therein a multiplicity of small perforations formed by a piercing tool without removal of material to provide around the edge of each perforation protruding burs directed toward said nozzle, said burs being heated white-hot by the flame in order to improve fuel combustion and thereby reduce the release of smoke and soot deposits in the combustion chamber.
