Fuel gas air mixture regulating method for fuel gas operated burner e.g. thermal value equipment, involves comparing measured burner or flame temperature with calculated burner or flame temperature

摘要

The method involves calculating a run of burner or flame temperature from an output temperature of a burner or a flame temperature. Fuel gas and combustion air stream are adjusted according to determined fuel gas volume or mass flow and combustion air volume or mass flow. Another burner or flame temperature is measured and is compared with the calculated burner or flame temperature, where the measured temperature at a preset point of time is larger or smaller than the calculated temperature at the point of time at a dynamic process, so that fuel gas flow or air mass is reduced or increased.
