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.

Methods and systems for clean-up of hazardous spills are provided. In some aspects, there is provided a system for burning an water-oil emulsion that includes an enclosure configured to hold a water-oil emulsion; one or more conductive rods disposed throughout the enclosure, each rod of the one or more roads having a heater portion to be submerged in the water-oil emulsion and a collector portion to project above the water-oil emulsion, wherein the collector portion is longer than the heater portion; and a delivery system for supplying an water-oil emulsion to the enclosure, the delivery system is configured to maintain a constant level of the water-oil emulsion in the enclosure as the water-oil emulsion is burned. The enclosure may further include one or more adjustable air inlets.

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.
