What are the specifications for a miniature boiler?

1. 12 ID, 6 ft gross volume, 18 ft heating surface, 80 MAWP

2. 16 ID, 5 ft gross volume, 20 ft heating surface, 100 MAWP

3. 14 ID, 4 ft gross volume, 15 ft heating surface, 90 MAWP

4. 18 ID, 7 ft gross volume, 25 ft heating surface, 110 MAWP

The correct answer is: 16 ID, 5 ft gross volume, 20 ft heating surface, 100 MAWP

The specifications for a miniature boiler are based on specific criteria that define its dimensions, volume, heating surface, and maximum allowable working pressure (MAWP). The choice that aligns with the standard definitions reflects those parameters accurately. In this case, the correct choice outlines a miniature boiler with a 16-inch internal diameter, a gross volume of 5 cubic feet, a heating surface area of 20 square feet, and an MAWP of 100 psi. These specifications are consistent with the established definitions for miniature boilers, which typically require specific minimums for heating surface and volume to function safely and effectively. This definition is pivotal for ensuring that the unit not only adheres to safety regulations but also delivers optimal performance within the parameters outlined for miniature boilers. The selected specifications reflect a balance of size and efficiency suitable for such boiler applications, making them an ideal fit for the classification.
