This invention concerns a boiler fitted with a burner suitable for wall heaters or built-in kitchen heaters in which a mantle-shaped heat exchanger made of pipe elements connected in parallel and/or series divides the boiler chamber into a combustion chamber and an exhaust chamber. The heat exchanger has openings for hot flue gases distributed over its mantle. The burner head disposed in the combustion chamber is suitable for burning oil and has a flame tube with an axial flame opening and a flame baffle element disposed at a distance from the flame opening which is constructed so that the flame is diverted into the space between the flame tube and the heat exchanger. In addition, a fire chamber mantle can be disposed between the heat exchanger and the flame tube to protect the heat exchanger from direct contact with the flame.
A fuel burning boiler, comprising a boiler housing, a burner head within said housing, a cylindrical heat exchanger dividing the boiler compartment into a combustion chamber and an exhaust chamber, and a flame deflector, said heat exchanger comprising passages distributed across its cylindrical surface for the hot exhaust gas to flow between said combustion chamber and said exhaust chamber, said burner head being positioned in the combustion chamber and comprising a fire tube with an axial flame opening directed at said flame deflector, said deflector being positioned at a distance from the flame opening, and being profiled such that the flame is deflected to the area between the fire tube and the heat exchanger.
A fuel burning boiler, comprising a boiler housing, a fire tube within said housing, a cylindrical heat exchanger dividing the boiler compartment into a combustion chamber and an exhaust chamber, a flame deflector piece creating a deflected flame, and a cylindrical combustion chamber shroud with passages for hot exhaust gas positioned in the combustion chamber between the fire tube and deflected flame, and the heat exchanger, the passages being so that the exhaust gas exits the combustion chamber shroud tangentially, the combustion chamber shroud being closed off near the blocking plate or the flame deflector piece.
The boiler of claim wherein the cylindrical combustion chamber shroud is closed off in a bottom area.
A fuel burning boiler, comprising a housing and a burner head positioned within said housing, said burner head being equipped with a centrally mounted fuel injector, capable of producing a conical shroud spray pattern, a baffle plate with an air vent, a fire tube positioned adjacent and downstream of the baffle plate;
