What does a super heater do to steam?

A super heater plays a crucial role in steam systems by increasing the temperature of steam without increasing its pressure. This process is important because high-temperature steam has a greater capacity to transfer heat, making it more efficient for applications such as power generation and heating.

When steam passes through the super heater, it absorbs additional heat from the combustion gases or another heat source. The result is steam that is at a higher temperature but remains at the same pressure. This characteristic allows the steam to possess more energy per kilogram, which enhances the overall efficiency of the system.

The other options do not accurately describe the function of a super heater. The super heater does not convert steam to liquid or reduce its efficiency; rather, it is specifically designed to improve performance by increasing steam temperature. Additionally, it does not increase pressure while keeping temperature constant; instead, it maintains the pressure during the heating process.
