Pressure steam temperature in the drum
Thread Content
In hydrogen production plants, the steam generated by the medium-pressure drum reaches a maximum temperature of only 370 to 380 degrees. What is the reason for this?
Then tell me what the saturation vapor pressure is in other places
It would be best to explain in detail the actual process conditions
The steam generated in the hydrogen production drum must be superheated to reach above 430°C
Yes, I took a look at ours; the medium-pressure steam generated in the superheating section of the converter’s flue gas has a temperature of only 370–380 degrees, with a drum pressure of 3.7 MPa. I’m not sure if this pressure is too low
370 to 380 degrees represents superheated steam; the steam temperature in the drum is around 240 degrees. It’s necessary to check whether there is a water injection cooling system in place.
Check whether the emergency cooling water is turned on; the temperature has dropped
Please provide the process parameters: has it been overheated? Check whether the depth of insertion of the thermometer is appropriate, and whether the insulation is sufficient
We have encountered this issue as well; there was a problem with the steam drum and the spin separator. For details, please message me privately at 476638073
There is a one-to-one relationship between this vapor pressure and temperature, right? If the pressure increases, then the temperature will naturally increase as well
The poster could please provide the design conditions – what is the designed superheat temperature?
