What is used on non-condensing turbines to protect the casing from excessive pressure?

• A. Safety relief valves
• B. Combination exhaust relieve valves
• C. Pressure regulators
• D. Temperature control valves

Answer: (B)

In non-condensing turbines, the protection of the casing from excessive pressure is a critical safety consideration. The appropriate device used for this purpose is a combination exhaust relieve valve. This type of valve is designed to open and relieve excess pressure that builds up within the turbine's casing, thus preventing potential damage due to overpressure conditions. Combination exhaust relieve valves are particularly effective in managing the steam and pressure dynamics in a non-condensing turbine system. They not only limit pressure but also help maintain operational efficiency by ensuring that excess steam is vented safely, thereby avoiding situations that could lead to structural failure or leaks. Other choices, such as safety relief valves and pressure regulators, serve distinct functions in different systems and applications. Safety relief valves are typically used in pressure vessels to prevent overpressure scenarios, while pressure regulators are designed to control the pressure of fluid in a system but do not specifically address the need for pressure relief in the casing of turbines. Temperature control valves manage thermal conditions rather than pressure, making them irrelevant to this specific function. Thus, the combination exhaust relieve valve is clearly the correct choice for protecting non-condensing turbine casings from excessive pressure.
