Let’s grow and mature through these Q&A sessions. Short answer question: How to determine the operating temperature of a gasification furnace. Adjustments should be made depending on the equipment, the type of coal, and the requirements for the composition of the gas, but it can serve as a useful reference for planning purposes. Generally, starting from an increase of 50°C in the ash fusion point of coal, the gasifier is operated for 72 hours to fully monitor its performance. Once no issues are detected, the furnace temperature is gradually reduced by 20°C; if it can still operate steadily for 72 hours, the temperature is further reduced by 20°C in two steps, with a reduction of 10°C per step. After the gasifier has been operating stably for 24 hours, its temperature is increased by 20–30°C, which then serves as its operating temperature.
