ABSTRACT:
A valve embodying combustion techniques for burners, especially the control technique for maintaining the fuel-to-air ratio at an optimum value over the entire range of low combustion to high combustion which ratio has close relation to nitrogen oxide emissions causing air pollution, to the consumption of fuel gas and to the safety and stability of combustion per se. The valve is installed mainly in the gas feed channel for a burner to freely regulate the rate of flow of gas to the burner accurately in conformity with the flow rate characteristics of air and to thereby provide an optimum fuel-to-air ratio. The valve is very useful in reducing nitrogen oxide emissions, saving energy and ensuring safety.
