Abstract
A cooking apparatus having a waste heat recovery system for incorporation into broilers, ovens, and toasters, the apparatus including a cooking chamber having a cooking platform, at least one air plenum disposed in the upper portion of the cooking chamber and having a plurality of air outlets for producing a focused forced air, a low pressure air source connected to the air plenums, a heating element or burner disposed under each of said air plenums, such that said curtain of focused forced air guides and directs heat from said heating element toward food product being cooked, and heat exchange pipes disposed between at least two of said air plenums. Radiant heat generated from the heating elements or burners rises in the cooking chamber and is retained between the air plenums to maximize heat transfer from the heated air to the heat transfer pipes, and thus to the low pressure air in the low pressure air system. The recycled heat enhances cooking.
