Which component reduces the steam temperature of saturated steam in a 150 psig steam system?

• A. Steam trap
• B. Heat exchanger
• C. In-line desuperheater
• D. Pressure regulator

Answer: (C)

In a 150 psig steam system, the component that reduces the steam temperature of saturated steam is the in-line desuperheater. A desuperheater is specifically designed to lower the temperature of superheated steam by introducing water into the steam line. This process absorbs the excess heat and brings the steam down to the desired saturation temperature. The reason this is the correct choice is that the desuperheating process effectively converts superheated steam back into saturated steam, which is often required for many applications in industrial and mechanical processes where you want to achieve the correct temperature and pressure for efficient heat transfer or process operations. Other components mentioned serve different purposes: a steam trap removes condensate and non-condensable gases from the steam system, a heat exchanger transfers heat between two fluids without mixing them, and a pressure regulator maintains a constant output pressure regardless of input pressure fluctuations, but none specifically target reducing steam temperature like the in-line desuperheater does.
