       Generally speaking, the saturation temperature of a single-stage gas furnace should be controlled at 56~61°C as much as possible. This can not only increase the calorific value of the gas and increase the CH4 content in the gas, but also make it less likely to form slagging or burn out the furnace grate. This is because under such temperature conditions, the CO content in the produced gas is the lowest, which may be only 28% to 29%. The calorific value of the gas is relatively the highest, and the coal consumption required for production will be reduced accordingly, thereby achieving the purpose of saving coal and reducing costs. The saturation temperature of a two-stage gas furnace is generally controlled at 55~63°C, which should be adjusted based on the gas quality and coal type. The purpose is to increase the calorific value of the gas, increase gas production, and reduce coal consumption. If the saturation temperature is low, the oxidation reaction will be violent. First, it is easy to increase the gas outlet temperature and take away too much sensible heat; second, the CO will increase, but the calorific value is not the highest; third, the temperature of the oxide layer is too high, which can easily cause large pieces of slagging, or even large areas of slagging. Fourth, if the ash layer is not controlled well, it is easy to burn out the furnace grate.
