Dry steam is a type of steam that contains no water droplets, making it a pure vapor. It is produced when water is heated to its boiling point and then further heated, allowing it to become a gas without any liquid present. This form of steam is often used in various industrial applications, such as power generation and sterilization processes. In contrast to wet steam, which contains both vapor and liquid water, dry steam is more efficient for transferring heat. It is commonly utilized in systems like steam turbines and heat exchangers, where maximizing energy transfer is essential for optimal performance.
