  • Superheated Steam - an overview | ScienceDirect Topics

    Steam is produced by heating a boiler via burning coal, gas, and other fuels. Water vapor that includes water droplets is described as wet steam . As wet steam is heated further, the droplets evaporate, and at a high enough temperature (which depends on the pressure), all the water evaporates and the system is in vapor-liquid equilibrium.

  • Saturated vs Superheat Steam Conditions - Nationwide Boiler Inc.

    Superheated steam has more energy and can work harder than saturated steam, but the heat content is much less useful. This is because superheated steam has the same heat transfer coefficient of air, making it an insulator and poor conductor of heat. Saturated steam is preferred for heating applications, while superheated steam is used mostly in
