noncondensing turbine

A noncondensing turbine is a type of steam turbine that does not use a condenser. In these turbines, the steam leaves at a pressure above atmospheric and is then utilized for heating or other processes before returning to the boiler as water. This makes noncondensing turbines an economical choice for power generation when there is a need for substantial amounts of heating or process steam, a concept known as cogeneration.1

Unlike condensing turbines, which condense steam below atmospheric pressure to maximize energy extraction and require significant cooling water, noncondensing turbines operate at or above atmospheric pressure upon exhaust. While condensing turbines are more efficient for large-scale electricity generation where efficiency is paramount, noncondensing turbines offer a practical solution for combined heat and power needs.1
