How many gage cocks are required for a boiler not exceeding 36 inches in diameter?

  1. 1

  2. 2

  3. 3

  4. 4

The correct answer is: 2

The requirement for the number of gage cocks on a boiler not exceeding 36 inches in diameter is two. This configuration is essential for accurate water level measurement and safety monitoring within the boiler system. Having two gage cocks allows for redundancy in case one gage fails, ensuring that the operator can still read the water level accurately from a functioning gage. Additionally, this design also facilitates proper maintenance and inspection over time. When the water level in the boiler drops below a certain point, unreliable readings could lead to operational issues or even hazards. Therefore, two gage cocks are mandated to promote safety and reliability in the operation of low-pressure boilers.
