For hydrogen production from dry gas, how is the steam supply condition and the inlet temperature of the reformer determined during catalyst reduction at your plant?

Our converter inlet temperature is above 450°C, the medium conversion temperature is above 220°C, and the system pressure is 1.0 MP. What temperature is used as the basis for the converter inlet? (One is the temperature before the raw material preheating stage, and the other is the temperature after it.) Is this temperature related to the steam dew point temperature? In other words, does the steam pressure and system pressure affect the temperature at which the steam is supplied? How does your factory determine it?
The general condition for steam supply is that the temperature at the furnace inlet is more than 50 degrees above the saturation temperature of the steam.
Do I have to look up the saturation steam dew point temperature again every time?
If the temperature of the medium is too close to the dew point temperature, when steam mixes with the medium, the steam pressure will decrease, leading to water deposition and damage to the converter
This dew point temperature is related to both the pressure of saturated steam and the system pressure, right? How do you check it each time?
Look it up in books or online, or memorize it
