The temperature of superheated steam at a certain pressure (instantaneous)

If this steam is used to purge the tower, will the temperature inside the tower also be around 350 degrees? Is there any relationship between the temperature of the steam inside the tower and its pressure? Does reducing the venting volume increase the pressure of the steam inside the tower, thereby raising its temperature? Thank you, extra points

In the initial stage of the steam tower, assuming the tower is cold, as the tower is heated, the temperature and pressure inside it are in equilibrium with those of saturated water vapor. Once the tower is fully heated, the steam temperature inside the tower should also be superheated; however, due to heat losses, the steam temperature inside the tower will be slightly lower than the inlet steam temperature. The temperature or pressure of the steam inside the tower depends on the amount of steam supplied and the amount of steam discharged. The greater the steam supply, the higher the temperature; the greater the vent volume, the lower the pressure. The steam supply or exhaust volume is too low; due to heat dissipation from the tower walls, this leads to a decrease in the temperature of the steam inside the tower.
