Can the fire hole cover be left open for a long time?

The temperature control here isn’t good; we often have to keep the fire hole cover open for long periods. How many of you face this issue? Let’s exchange ideas.
1# Oolong Knife: The frequent need to open the fire hole cover indicates that your heating furnace is not being managed properly. ”The three doors and one panel are not adjusted properly; temperature control is inadequate, which forces us to keep the viewing ports open in order to monitor the flame. You need to thoroughly investigate this issue – hire a boiler expert.
Keeping the fire viewing hole open for an extended period first affects the temperature of individual vertical flues, and then it impacts the airflow throughout the combustion chamber; as a result, the temperature across different rows becomes unstable.
It mainly affects the airflow throughout the combustion chamber, resulting in instability in the cross-row temperatures.
Of course not. If normal heating doesn’t work, it’s due to certain specific issues; we should address those issues one by one. We only open the small cover on the fire viewing port in cases where there are significant leaks that cannot be addressed in a short period of time, to prevent damage to the chute. In one case, previous management issues caused the sloping entrances of various fire channels to become mostly melted and blocked; it was impossible to resolve this situation. Even if those openings were kept open for an extended period to allow exhaust gases to escape through them, it still didn’t prevent the sloping entrances from being further blocked by free carbon produced as a result of incomplete combustion.
Frequently opening the fire hole cover indicates that your heating system is not properly designed, which results in high temperatures that cannot be reduced. Cooling by this method is not advisable; although it can reduce the temperature, it affects the uniformity of heating in the horizontal and vertical directions. Could you please provide details about your heating system and furnace type, so that I can offer suggestions on how to make improvements?
The fire hole cover cannot be left open for a long time, as this can affect the airflow and impact the uniformity of temperature in the combustion chamber
There are leaks in the walls of our regenerative furnace; sometimes we also open the sight glass covers
Leaving the fire hole cover open for an extended period can disrupt the airflow, affecting the temperature uniformity in the combustion chamber and thus hindering complete combustion
