Inject steam at different pressures into the reactor
Thread Content
The temperature of a certain reactor bed layer in the unit is around 240 degrees. To prevent the reactor from experiencing excessive temperatures, steam pipelines have been installed at the inlet for cooling purposes. 0.3 kilograms of steam at 140 degrees and 3.5 kilograms of steam at 280 degrees are used; if the temperature of the reactor bed layer rises, injecting 0.3 kilograms of steam can help lower that temperature. If 3.5 units of steam are injected, will the bed temperature rise or fall? I’m not quite sure; please explain, experts. Thank you. Many thanks. Bonus points
How is cooling achieved when steam is introduced? Is it by participating in the reaction, or by using the temperature difference between the steam and the bed layer to reduce the reaction temperature?
I think the temperature will still drop; when steam condenses into water, it also causes a decrease in temperature.
The temperature of medium-pressure steam is around 400 degrees, what do you think?
The essence of injecting steam is to cool down; it’s just that the cooling effect varies depending on the temperature of the steam
