A gas burner, for use in sterilizing compost, weed killing, bitumen burning or preparing, water heating or as a portable burner, comprises one or more jets A connected to a source of fuel under pressure and mounted in a support B to be spaced coaxially from the inlet of an injector tube E which is mounted in a casing D having an outlet which flares laterally and tapers in cross-section to provide a long narrow mouth, the casing having holes F of predetermined size in predetermined positions in its flared walls through which additional air is sucked to supplement the gas/air mixture in its passage through the casing D. Figs. 1 and 2 show a burner unit comprising a single jet A screwed into the support B which is spacedly secured to a back plate D<SP>1</SP> of the casing D, the casing having a rear portion of rectangular shape in plan from which the outlet or front portion flares laterally and tapers in cross-section. The holes F are disposed in the upper and lower walls of the casing one in each said wall of the rear end, three adjacent the casing mouth and two in an intermediate position as shown. Two or more such units may be disposed side by side in a composite casing as shown in Fig. 4 to provide an elongated flame. Figs. 7 and 8 show a burner comprising two superposed jets a co-operating with injector tubes e mounted in a square-sectioned rear end of a casing d the outlet of which comprises three superposed laterally flared mouths of tapering cross-section disposed with the adjacent edges of their inlet ends aligned with the axes of the tubes e. The front rows of holes f in this case are provided in the upper and lower walls of each of the three mouths. Batteries of such burners may be mounted on a common supply pipe for heating large containers.
