ABSTRACT:
A microwave convection oven in which a gas burner positioned outside the oven cavity has its combustion products circulated through the oven through screens for preventing escape of the microwave energy from the oven cavity with the burner being of the multi-ported type providing high burner density and having secondary air closely adjacent all portions of the burner to reduce its incondescent flame length while permitting the burner to be positioned in a region between the screened vapor outlet region the oven and the inlet of a blower system for mixing the output of the burner with the vapor drawn from the oven thus the temperature of the vapor outlet region is maintained below that at which ionization of the vapor being drawn from the oven might produce leakage of microwave energy through the screen.
