Abstract: This relates to a method of operating a burner under conditions of stoichiometric combustion, wherein liquid fuel and combustion air are combined in a essentially constant ratio within a mixing and atomizing chamber, whereby a negative pressure is produced within said chamber owing to the guiding and metering of the air, said negative pressure serving to draw in fuel into said chamber. Furthermore, the invention relates to a burner assembly for carrying out the method.

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.

Abstract: An apparatus for producing oxygen-free combustion gases, comprising a combustion chamber provided with a cooling jacket or shell and wherein liquid or gaseous hydrocarbons are burnt with combustion air and subsequently cooled through spray cooling by water introduced through nozzles into the rear portion of the combustion chamber, whereupon secondary cooling and scrubbing take place within a secondary cooling zone subsequent to the plenum chamber of said combustion chamber and provided with a plurality of gas outlet ports. That spray heads are arranged in the region of said gas outlet port(s), to produce a spray stream or jet directed to said outlet ports. A chamber is connected to said outlet port which chamber is surrounded by a wall provided with at least one gas outlet port, with the stream or jet of said spray heads being aligned with said gas outlet ports.
