What are the conditions for steam supply in dry gas hydrogen production?

Is the converter inlet temperature greater than 450 degrees Celsius? Some values indicate more than 320; is this related to the steam dew point temperature?
In principle, the temperature of the dry gas entering the furnace should be at least 50 degrees higher than the steam dew point temperature in order to enable steam mixing. The saturation temperature of 3.5MPa steam is 242 degrees; the temperature at the furnace inlet must be at least 300 degrees to supply steam. It can certainly be higher; the main purpose is to prevent steam from liquefying after entering the medium system and damaging the converter.
Yes, it needs to be above 50°C above the dew point in order to be put into use; otherwise the catalyst will be damaged. Our facility requires a temperature of no less than 420°C℃
Mm-hmm. With all other conditions unchanged, does a higher steam pressure result in a higher dew point temperature?

Yes, the higher the steam pressure, the higher the dew point temperature.
