Addition of boiler feedwater volume to the original start-up steam volume in the full low-variation transformation

During the initial driving process, the designed gas flow rate is 1 standard cubic meter per hour; after the transformation and heating sulfidation are complete, the gas flow rate becomes 1.5 standard cubic meters per hour. Steam is added when the temperature at various points in the converter catalyst exceeds 220 degrees. What determines the amount of steam to be added? Since it is an exothermic reaction, the temperature will definitely rise upon adding steam. If the temperature becomes too high, should more steam be added or less? If more steam is continued to be added, will the temperature keep rising, and if not, to what extent can it drop? Chemical engineering discussions
During normal operation, the amount of steam added should be adjusted as needed, primarily based on the temperatures at various points of the converter catalyst. Generally, when the temperature at various points of the catalyst is below 220 degrees, an appropriate amount of steam needs to be added to raise the temperature and facilitate the reaction. When steam is added, the temperature rises, but if steam continues to be added, the temperature does not keep rising indefinitely. This is because the heat generated by the reaction and the heat dissipation of the steam can reach a state of equilibrium. If the temperature is too high, the amount of steam added should be reduced appropriately; otherwise, it will affect the efficiency of the reaction or even cause it to get out of control. As for the specific level that can be achieved, various factors need to be considered, such as reaction rate, type of catalyst, and air flow within the furnace. This requires adjustment and control in practice based on experimental data and experience. .
If steam is kept being added, shouldn’t the temperature drop?
