Where are steam safety valves typically installed on boilers, apart from the super heater?

• A. Steam drum
• B. Boiler shell
• C. Feedwater pump
• D. Expansion tank

Answer: (A)

Steam safety valves are essential components in boiler systems designed to prevent overpressure conditions. They are installed in designated locations where they can effectively monitor and release excess steam or pressure to maintain the safety and operational limits of the boiler system. The steam drum serves as the primary vessel in a boiler system where steam is collected from the water during the heating process. Installing safety valves on the steam drum allows them to effectively release steam directly from the area where pressure is typically highest. This strategic placement ensures timely intervention, preventing potential hazards such as boiler explosions due to excessive pressure build-up. In contrast, the other options do not serve the same function as the steam drum. The boiler shell is the outer structure and not the primary point of pressure regulation, while the feedwater pump is involved in delivering water to the boiler and not in pressure management. An expansion tank accommodates thermal expansion of the water but is not positioned to relieve steam pressure from the boiler system effectively.
