How many gauge cocks are found on a boiler with less than 36 inches and 100 sq ft of surface area?

1. 1

2. 2

3. 3

4. 4

The correct answer is: 2

In a boiler that has less than 36 inches in height and a surface area of up to 100 square feet, the typical requirement is for two gauge cocks. These gauge cocks are essential safety devices that allow for the measurement of the water level inside the boiler and help ensure proper operation. While each boiler design can have variations, the design standard typically specifies that such boilers should be equipped with two gauge cocks, which provide operators with reliable readings of the water level. This setup not only enhances the accuracy of water level indicators but also serves as a backup in case one gauge fails. For larger boilers or those exceeding certain dimensions, the numbers of gauge cocks may increase to ensure further accuracy and redundancy, but for a boiler of the specified size and capacity, two is the norm. Hence, the correct answer reflects the standard for smaller low-pressure boilers in maintaining safe and effective operation.
