The glass melting furnace flame space atmosphere control method of the present application measures the oxygen content measurement value, the combustion-supporting air flow measurement value and the combustion-supporting air temperature measurement value in real time, thereby obtaining the oxygen content change value, and when the fluctuation range of the oxygen content change value exceeds the fluctuation range, the combustion-supporting air flow measurement value is adjusted, so as to realize real-time dynamic adjustment, and further realize fine control of the glass melting furnace flame space atmosphere, thereby ensuring that the combustion-supporting air flow in the flame combustion is in a stable state for a long time, and realizing long-term stability of the flame space atmosphere.

The distributed control module is used to, when the current oxygen content change value exceeds a preset fluctuation range, obtain a target combustion air temperature compensation setting value based on the oxygen content change value and the current combustion air temperature compensation setting value, wherein the target combustion air temperature compensation setting value corresponds one-to-one with the combustion air temperature compensation setting value and the oxygen content change value; it is also used to, based on the target combustion air temperature compensation setting value and the current combustion air temperature measurement value, adjust the current combustion air flow measurement value to obtain an adjusted target combustion air flow setting value; and it is also used to provide combustion air based on the adjusted target combustion air flow setting value.
