Abstract: A campstove burner includes a burner box which is located above the burner pan of the burner. The burner rings are positioned between the burner pan and the burner box, and a fuel and air mixture within the burner box flows through the burner rings where it is ignited. Since the burner box is located above the burner pan, liquid fuel within the burner box will flow through the burner rings and will be ignited in the burner pan outside of the burner box. The burner box includes an L-shaped aspirator tube for mixing fuel and air. An inlet end of the aspirator tube communicates with a source of primary combustion air, and a fuel tube extends into the outlet end of the aspirator tube for aspirating combustion air into the inlet end. The burner box includes a generally cylindrical sidewall and the outlet end of the aspirator tube directs the fuel and air mixture generally tangentially to the inside of the cylindrical sidewall to promote swirling and mixing of the fuel and air.

Abstract: A method of producing a hot gas flow by combustion of preferably liquid fuels, by the following steps:(a) atomizing the liquid fuel to form fine particles;(b) further atomizing the thus generated fuel particles with the aid of combustion air supplied as atomizing medium, and reducing the mean fuel particle diameter to less than one-half of the mean diameter obtained in step (a);(c) burning the fuel-air mixture within a flame cone extending on an axis A, under stoichiometric conditions or with an excess of oxygen within an air duct;(d) introducing a stream of cold air to be heated or of another medium, optionally including components adapted to be oxidized, in a plane E extending substantially perpendicularly to axis A.Further, the invention relates to a hot gas generator or incinerator for carrying out the method, comprising a straight air conducting pipe which has coaxially positioned therein a burner for liquid fuels, including a two-stage atomizing assembly for the liquid fuel.
