  • Is superheated steam pressure and temperature the same as

    Answer (1 of 5): No it isn't. 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 superheaLearn More
