Document Type and Number:
WIPO Patent Application WO/2024/048006
Kind Code:
A1
Abstract:
An air ratio control system 50 adjusts the ratio of fuel gas G and combustion air Air supplied to a burner 20, and when the fuel gas and combustion air are combusted in a furnace 10, the oxygen concentration in the furnace detected by an oxygen concentration sensor 51 is output by an output control device 52 to an air ratio control system to adjust the ratio of fuel gas and combustion air supplied to the burner. Meanwhile, when the oxygen concentration in the furnace detected by the oxygen concentration sensor changes significantly, the output control device does not output the detected oxygen concentration in the furnace to the air ratio control system, and the air ratio control system maintains the ratio of the fuel gas and combustion air supplied to the burner.
