Question: 1 / 495

Mufflers in a boiler system primarily prevent which of the following?

Vibration

Condensation

Back pressure

Mufflers in a boiler system primarily function to reduce noise generated by the expansion and contraction of the steam and from the machinery involved in boiler operations. However, they also serve to mitigate back pressure in the system. Back pressure can occur when steam or gases encounter resistance flowing through pipes, which can lead to inefficiencies in boiler operation. When a muffler is utilized, it helps to control this back pressure, allowing for smoother flow and better overall efficiency.

While other options like vibration, condensation, and heat loss can be managed through different components and practices in a boiler system, they are not the primary function of a muffler. Mufflers focus more directly on the sound and flow characteristics of the system, maintaining optimal performance by preventing undue pressure build-up that can arise from obstructions or structural issues in the piping.
