Does the opening degree of the induced draft fan affect the temperature of the converter?

The blower and exhaust fan can adjust the negative pressure in the furnace; what effects does opening or closing the valves have on the furnace temperature?
Your question makes no sense. In principle, the air supply volume is adjusted based on the oxygen level inside the furnace, while the amount of flue gas drawn out is adjusted according to the negative pressure in the furnace. Your question concerns exactly the levels of air supply and flue gas extraction. Under unchanged other conditions, if these values are high, more heat will be carried away by the flue gas, resulting in lower thermal efficiency of the furnace and a lower furnace temperature; if they are low, it may lead to incomplete combustion and secondary combustion
With a constant fuel feed rate, increasing the exhaust fan speed will lower the temperature of the furnace. Increasing the amount of fuel will raise the temperature of the furnace
It mainly depends on the oxygen content in the flue gas.
Sure, under a certain negative pressure, if the fans and exhaust fans are operated at high capacity, the air flow velocity increases, resulting in greater heat loss
Of course. Both the negative pressure in the furnace chamber and the oxygen level affect the combustion efficiency of the furnace
