What is the effect of too high or too low saturation temperature on the gasification process?
It’s too low; there’s a risk that the temperature of the heating medium will become too high, causing rapid vaporization and resulting in overpressure.
What is the effect of too high or too low saturation temperature on the gasification process? If the saturation temperature of the gasifying agent is too low, the content of water vapor in it is very low while the content of air is high; as a result, oxidation reactions increase whereas gas production reactions decrease.
The saturation temperature being too low accelerates the vaporization process, causing the flame layer to move downward. Too high a saturation temperature weakens the gasification process and causes the flame layer to rise.
What is the impact of excessively high or low saturation temperatures on the gasification process?...... A too low saturation temperature indicates a low content of water vapor in the gasifying agent； A too high saturation temperature indicates a high content of water vapor in the vaporizing agent. The amount of water vapor has a significant impact on the reaction temperature inside the furnace: more of it lowers the temperature, while less of it raises it (here, the T2 temperature of the raw coal is the main factor considered). Next is the change in the gasification reaction caused by this.
