Steam is categorized into three primary types based on its physical state, thermodynamic properties, moisture content, and temperature profiles: wet steam, dry saturated steam, and superheated steam. Wet steam contains a mixture of invisible water vapor and entrained liquid water droplets, typically found during initial pipe warm-up phases or low-efficiency boilers. Dry saturated steam exists precisely at the boiling temperature corresponding to its pressure, containing zero liquid water droplets, and serves as the standard, highly efficient type used for building radiators and industrial heat exchangers. Superheated steam is created by heating dry saturated steam further past its saturation point at a constant pressure, resulting in a high-temperature gas phase utilized in power plants to drive high-velocity industrial turbines without condensation damage.
