What is the purpose of installing a muffler on a safety or relief valve?

Enhance sound quality
Prevent back pressure on a boiler
Reduce emissions
Increase flow rate

The correct answer is: Prevent back pressure on a boiler

Installing a muffler on a safety or relief valve primarily aims to prevent back pressure on a boiler. When a safety or relief valve opens, it releases steam or gas to relieve excess pressure within the boiler. A muffler can help to dissipate the energy of the escaping fluid without creating excessive resistance. This is crucial because any back pressure can hinder the valve's effectiveness, potentially compromising safety by preventing the valve from fully opening when needed. By reducing back pressure, the muffler ensures that the valve operates correctly and allows for efficient pressure relief, protecting the boiler from potential damage due to overpressure situations. This aspect is vital in maintaining the safety integrity of boiler systems, contributing significantly to the overall operational safety.
