Abstract
A burner assembly combines air and fuel to produce a burn firing into a downstream tube. The assembly includes a funnel formed to include an inlet, an outlet, and an air and fuel mixing region therebetween. The funnel also includes a cylindrical intake end at the inlet and a conical side wall mating with the cylindrical intake end and converging from the cylindrical intake end toward the outlet to fire a burn initiated in the mixing region into a tube coupled to the outlet of the funnel. The assembly also includes a system for supplying a gaseous fuel to the mixing region in the funnel and a system for introducing combustion air into the mixing region through the inlet of the funnel. The combustion air mixes with the gaseous fuel in the mixing region to produce a combustible mixture. The combustible mixture in the funnel is ignited to fire a burn into the downstream tube, which tube is coupled to the outlet end of the funnel and extended into the interior solution-containing region of an adjacent solution tank, so that combustion begins, progresses, and transitions gradually into the downstream tube.
