What should be the maximum temperature of the refractory layer in a gasification furnace?

As the title suggests, I’m seeking advice from those who are more experienced~ Thank you!

Different refractory materials have varying maximum temperatures; it is generally believed that the maximum temperature on the fire-facing side of the corundum bricks used in the refractory lining of gasification furnaces should not exceed 1600 DegC, and it is preferable that this temperature remain below 1450 DegC during operation. The lower the temperature on the cold side of the refractory lining, the better its insulating properties are. Generally, the maximum temperature on the shell side of pressurized gasification furnaces should not exceed 330 DegC
The maximum temperature limit for refractory bricks specified in the instruction manuals provided by most refractory brick manufacturers is 1600°C. However, the normal operating temperature of a gasification furnace is generally below 1450°C; by using bricks with the thickness and dimensions specified in the design, the insulating temperature at the furnace wall ensures that the design requirements for that wall are met. Given the characteristics of most coal types in our country, it is best to keep the operating temperature of the gasifier below 1350°C; this ensures normal operation while also extending the service life of the refractory bricks.
