Pressure steam refers to steam that is contained within a closed system and exerts a pressure greater than atmospheric pressure. This elevated pressure is typically generated by heating water in a sealed vessel, such as a boiler or a pressure cooker. As water heats up, it transforms into steam, and in a confined space, this steam accumulates, increasing the internal pressure.

The properties of pressure steam are distinct from those of atmospheric steam. It has a higher temperature and greater energy density. This increased energy is what makes pressure steam a valuable tool for various applications, particularly those requiring heat transfer and mechanical work.

Common applications of pressure steam include industrial processes like sterilization, cooking, and the operation of turbines for electricity generation. In domestic settings, pressure cookers utilize pressure steam to significantly reduce cooking times by raising the boiling point of water. Understanding the principles of pressure steam is crucial for safe operation of these systems, as the high pressures involved can pose hazards if not managed correctly. Safety valves and pressure gauges are essential components in systems that employ pressure steam to prevent over-pressurization and ensure safe operation.
