What is a common consequence of a deep vacuum in a boiler system due to clogged strainers?

1. Increased pressure

2. Risk of boiler explosion

3. Complete system failure

4. Loss of water supply

The correct answer is: Complete system failure

A deep vacuum in a boiler system can lead to complete system failure primarily because it affects the normal operation and integrity of the entire system. When strainers become clogged, they impede the flow of water into the boiler, leading to insufficient water levels. This can result in various issues such as overheating of the boiler components, which may lead to warping or other structural failures. Moreover, a significant vacuum can create scenarios where air leaks into the system, leading to corrosion and further degradation of the boiler materials over time. Eventually, these factors can culminate in a situation where the system can no longer operate safely or efficiently, necessitating a shutdown or extensive repairs. Therefore, complete system failure is a plausible and serious consequence of a deep vacuum caused by clogged strainers. While other consequences may also stem from such a vacuum, including risks of pressure variations and water supply challenges, the overarching concern remains the integrity and operational viability of the entire boiler system.
