Abstract
A heat treating furnace is provided with high momentum burners for uniformly heating each work item therein primarily by convective heating. A plurality of work items are spaced in a row on a furnace base and enclosed by an outer cover sealed to the base to define an enclosure therein. High momentum burners are orientated in a predetermined manner in the outer cover to fire jet streams of hot gases into the enclosure. The jet streams rapidly entrain the furnace gases to promote a gas stream of uniform temperature which swirls rapidly about each work item effecting uniform heating of each work item primarily by convection. The furnace is further provided with an efficient internal recuperator arrangement which also functions as the flue for the furnace.
