Abstract (en)
[origin: US2006204911A1] A unique control system is provided for optimizing and effecting efficient combustion of gas appliances by controlling the proportion of fuel and air variables. The control system provides continuous active feedback of the combustion event by detecting the level of exhaust gases such as CO<SUB>2 </SUB>to trigger the modulation of a gas valve. Based upon the detected level, a control signal is generated by the system and received by a processor to adjust pressure and gas flow for future combustion events. Accordingly, the control system varies the proportion of air to fuel inflow to a prescribed optimum range thereby achieving efficient fuel combustion.
