ABSTRACT:
Heat shield and ventilation system for a pizza oven uses cooling air drawn mainly from the outside, which is directed around all four sides and over the top of the pizza oven by a heat shielding shroud that covers the top, back and ends, but leaves the front of the oven free for access to the doors that extend across most of the oven front. The shroud side panels are provided with deflectors that redirect air to flow forwardly along the oven sides to cause it to follow in a path flowing laterally inwardly and upwardly along the oven front, providing a curtain of cooling air that mixes with and entrains the heated air at the oven front face to be drawn into an exhaust port at the center of the top of the oven front. The shroud provides both cooling air passages and passages for intake of combustion air into the oven burners and also provides passages between the oven and the shroud for flow of exhaust gases to be combined with the exhausted ventilation air which entrains the heated air from the exterior surface of the oven.
