Superheated steam cannot exist in a boiler drum, it can only exist in a moving fluid. This is why the superheater tubes are separate from the rest of the boiler tubes, where the steam has to be moving to have heat imparted to it. If there is no movement, the superheater tubes could burn out.

If the same steam leaving the boiler is not retained, and the amount of incoming heat is maintained, the energy flow to the boiler will be greater than the energy that flows out. This excess energy will raise the pressure, which in turn will lead to saturation temperature increases, because the temperature is related to pressure saturated steam.
