Abstract
A gas and solid fuel burning chamber is provided with a control system for the safe and efficient operation of a gas burner. The simple control system uses multiple thermocouples in series to permit the safe operation of the gas burner in a vented device without the need for a draft hood. A combination of gas and solid fuel is demonstrated where gas can be used to start the solid or as an independent source of heat. The control system comprises generally of thermocouples for measuring the flame temperature, the combusted gas temperature and the overall chamber internal temperature and producing signals to regulate the flow of fuel to the gas burner in response thereto.
