Critical point is the state of water at which no latent heat is required to convert water into superheated steam.
Above this point water directly converted into superheated steam.
theoretically critical point of water is 221.4 bar and 374.2 deg C .
Superheated steam is steam at a temperature higher than water's boiling point
A spout of superheated water refers to a forceful stream of water that has been heated to a temperature above its boiling point without actually boiling. This can occur in geothermal features like geysers, where water becomes superheated due to pressure and volcanic activity underground, before erupting to the surface in a high-pressure release.
Superheated steam is often used in a distillation column to provide efficient heat transfer for the separation process. The high temperature of the superheated steam helps to vaporize the liquid components being distilled while maintaining a consistent temperature throughout the column. This can improve the overall separation efficiency and allow for better control of the distillation process.
Subcooled vapor refers to a vapor that is at a temperature lower than its saturation temperature at a given pressure. In other words, it is a vapor that is in a superheated state but exists at a temperature below its boiling point at the current pressure. Subcooled vapor is not in equilibrium with its liquid state and is considered to be in a superheated state.
To fully specify superheated vapor, you need to know the substance involved (e.g., water, steam), its pressure, temperature, and specific volume. Additionally, information on the phase state (gas), the degree of superheat, and any relevant thermodynamic properties like enthalpy or entropy may also be required.

No, steam is not superheated water. Steam is the gaseous form of water that is created when water is heated to its boiling point and vaporizes. Superheated water is water that has been heated beyond its boiling point and exists in a state where it is hotter than its boiling point.

Distilled water contains no impurities so it can become superheated. Superheated water is water heated above boiling point when it is not boiling. When the water is superheated, it will be very dry to turn the turbines so the turbines are not wet
because if the steam is not superheated the remaining water droplets reduce efficiency and can cause corrosion and pitting. +++ Nearly! Saturated steam, as non-superheated steam is called, is really only steam at the pressure and temperature in the boiler. Once it starts to expand as a gas in doing its work, the pressure and temperature fall and condensation will set in, leaving less and less useful water-vapour to act as a gas. Hence, as you say, the efficiency falls.
In order for a high-temperature boiler or steam engine to produce superheated water or steam, the water must first be heated to its boiling point and then subjected to additional heat beyond this temperature without increasing pressure. This is typically achieved by passing the steam through a superheater, where it is exposed to hot gases or additional heat sources. The process increases the temperature of the steam, enhancing its energy content and efficiency for various applications, such as power generation or industrial processes. Proper control of temperature and pressure is essential to prevent any risk of damage to the system.
A desuperheater cools superheated steam by introducing a cooling medium, typically water, into the steam flow. As the water sprays or mixes with the steam, it absorbs heat, causing the steam's temperature to decrease. This process often involves heat exchange and can efficiently bring the steam down to a desired saturation temperature without condensing it entirely. The result is cooler, lower-energy steam suitable for various applications.
