Abstract
Disclosed is a gas-fired oven for heating food by steam and/or dry convection. The oven has a heating chamber; an atomizer for producing an atomized water spray; a source of a combustible gas mixture; and a burner-heat exchanger. The gas fired burner-heat exchanger receives and combusts the mixture and isolates hot combustion gases from the heating chamber so pure steam is furnished to the heating chamber. The heat exchanger receives hot combustion gases, and vaporizes atomized spray circulated over its external surface to produce steam for heating an article in the heating chamber. The amount of steam in the heating chamber is measured and controlled by monitoring a temperature in a drain.
