Oven drying issue

If, during the heating process, the furnace temperature reaches 800 degrees and suddenly the pump fails causing the cooling ring to lose water supply, the gasification furnace stops heating and ceases to operate in negative pressure mode. Once the pump is repaired, can water be supplied to the cooling ring again to resume the heating process? If water is supplied again, will it have an impact on the quenching ring since the water supply to it was interrupted before? I would be very grateful if any fellow sea traveler could let me know.
Sure. The reasons are as follows: 1. The water wall is always in operation; 2. The cooling water loop is located at the lowest part of the water wall, so its temperature is not high; 3. The hot gases do not pass through the cooling water loop. In normal operating conditions, if there is a failure in the cooling water system, it is necessary to shut down the furnace
There is no water supply – is the water wall still in operation? If it is baked at 800 degrees, the baking process stops due to the water supply being cut off to the quenching ring, and negative pressure extraction ceases; as a result, the high-temperature gases inside the furnace do not flow. Due to thermal radiation, what temperature might the quenching ring reach under such conditions? If the quenching ring loses water supply, can water still be supplied to heat the furnace? Could you explain it in detail? Thank you.
1. The water used for the water wall is boiler water, while the water used for cooling is treated ash water; they are not the same type of water. 2. The flow rate of the cooling water is controlled by a interlock mechanism, and the interlock is activated as long as the flow has not been completely stopped (FASLL)

It still has an impact, right! When the water supply is cut off suddenly while the temperature is quite high, the temperature of the cooling ring rises. If water is added again after some time with a low water temperature, it can damage the cooling ring. In such cases, it’s best to lower the furnace temperature before adding water again! ! !
