Does a low tray temperature during furnace drying have an impact on the bricks above the slag outlet? Can it be assumed that a low tray temperature corresponds to a low furnace brick temperature, with the two being in a proportional relationship?

The effect of tray temperature on furnace bricks
I believe that the temperature of the support plate during furnace heating is closely related to the negative pressure; I think the temperature of the support plate is proportional to the temperature at the syngas outlet
Does the temperature of the tray affect the temperature of the furnace bricks at the slag outlet in the combustion chamber?
The tray temperature is the temperature transmitted by the furnace bricks.
During furnace drying, the temperature of the rotating support plate is indeed closely related to negative pressure and the amount of fuel gas used. More fuel gas combustion generates more heat, but a higher negative pressure leads to more heat being carried away; the same principle applies in reverse. When reaching the high-temperature zone, it is possible to check the temperature of the surface thermocouples and compare it with previous values.
During furnace heating, if the furnace chamber thermocouple reads 1200 degrees, the tray temperature is 140 degrees. Can we assume that the temperature of the taphole brick is also low?
The tray temperature is low during furnace heating. The furnace bricks at the taphole transfer heat efficiently due to the large temperature difference. Will this lead to an increased temperature difference between the thermocouple in the middle of the furnace and the temperature at the slag outlet?
In the later stages of furnace heating, the temperature remains more or less constant. If there is concern that the temperature of the bricks at the bottom of the furnace is too low, the constant-temperature period can be extended, or the extraction rate and the amount of fuel gas can be increased to achieve a new equilibrium temperature. Furthermore, a large amount of quenching water can also result in a lower temperature of the brick support plate
