A combustion chamber assembly unit, for a vaporizing burner, includes a combustion chamber housing with a circumferential wall extending in a direction of a combustion chamber housing longitudinal axis (L) and a bottom area (14), together defining a combustion chamber (16). The bottom area (14) includes an evaporating medium carrier (18) and on a side facing the combustion chamber (16), a porous evaporating medium (20). A first flame diaphragm (36), with a first diaphragm opening (38), is provided on the circumferential wall (12). A second flame diaphragm (40), with a second diaphragm opening (42), is provided at an axial distance to the first flame diaphragm (36) on an axial side facing away from the porous evaporating medium (20). An air admission opening arrangement (44) is provided in the circumferential wall (12) and includes an air admission opening (46) between the first flame diaphragm (36) and the second flame diaphragm (40).

A combustion chamber assembly unit, especially for a vaporizing burner and particularly especially for a vehicle heater, includes at least two combustion chamber elements (12, 20, 26, 32, 50, 52, 64, 102, 126) with wall areas (12, 34, 46, 54, 64, 104, 130, 140, 142). The at least two combustion chamber elements are arranged in a radially staggered pattern in relation to a longitudinal axis (L) of the combustion chamber and are fixed to one another by laser welding.

A heater comprises a combustion chamber and a jacket extending about the combustion chamber. There is a fan having an output which communicates with the combustion chamber to provide combustion air. There is also a fuel delivery system having a variable delivery rate. A burner assembly is connected to the combustion chamber. The burner assembly has a burner mounted thereon adjacent the combustion chamber. The burner receives fuel from the fuel delivery system. There is an exhaust system extending from the combustion chamber. An oxygen sensor is positioned in the exhaust system to detect oxygen content of exhaust gases. There is a control system operatively coupled to the oxygen sensor and the fuel delivery system. The control system controls the delivery rate of the fuel delivery system according to the oxygen content of the exhaust gases.

A film evaporator burner arrangement (1) is provided, having: a combustion chamber arrangement comprising a combustion chamber (2) for the conversion of a fuel-air mixture with the release of heat, which extends in the axial direction along a longitudinal axis (Z); a combustion air supply (5) for the supply of combustion air, which is configured such that the combustion air is supplied with a tangential flow component to at least one combustion air inlet (8) of the combustion chamber arrangement; a film evaporator surface (4) for evaporating liquid fuel originating from a fuel film (10), which is arranged at a rear wall (3) axially rearward of the combustion air inlet (8); and a fuel supply (9) for the supply of liquid fuel to the film evaporator surface (4).

The invention relates to an evaporator burner (100) for a mobile heating device operated with liquid fuel, comprising: a mixture-preparing region (2) for mixing fuel with combustion air to form an air-fuel mixture, a fuel supply (1) for supplying liquid fuel to the mixture-preparing region (2), a combustion-air supply (B) for supplying combustion air to the mixture-preparing region (2), a reaction region (3) arranged downstream of the mixture-preparing region (2) for reacting the air-fuel mixture, heat thus being released, and an evaporator body (9) for evaporating the liquid fuel, which evaporator body extends in an axial direction in the mixture-preparing region (2) at a distance from a side wall and has an outer peripheral surface designed as a fuel-evaporating surface, which outer peripheral surface is arranged in such a way that the supplied combustion air flows around the outer peripheral surface.

A burner includes a generally cylindrical reactor chamber (1) including a housing (1) having a proximal end (1p) and a distal end (1d). In the distal end of the reactor chamber (1) there is provided a catalyst (4). A fuel inlet (7) is provided in the proximal end of the reactor chamber. There are also a plurality of air inlets (22, 23; 24) arranged in the reactor wall at the proximal end. The inlets are configured to provide a rotating flow of the air injected into the reactor chamber. There is also provided a flow homogenizer (8; 30) extending over the cross-section of the reactor chamber at a position between the fuel inlet (7) and the catalyst (4).

A flow-directing element for a heating apparatus, in particular a heating apparatus with an evaporator burner, having a body which comprises a laterally arranged inflow region on an underside of the flow-directing element, having a centrally arranged outflow region, which includes a through-passage from an underside of the flow-directing element to an upper side of the flow-directing element, the upper side being located opposite the underside, and having at least one guide element, which is arranged such that it allows flow to be guided from the inflow region to the outflow region.

A furnace which receives input information of various sources, distinct from a thermostat, and can vary heat output based on the input information. Examples of input information include without limitation exhaust temperature, temperature near the heat exchanger compartment, temperature sensors within the housing, air pressure, motor RPM, and/or motor amperage. Heat output may be varied by one or more of combustion fan output, fuel flow to burners, combinations or other ways.
