New York Low Pressure Boiler COF Practice

What is the required square footage of heating surface for a fusible plug?

1. 25 sq ft

2. 50 sq ft

3. 100 sq ft

4. 150 sq ft

The correct answer is: 50 sq ft

The required square footage of heating surface for a fusible plug in a low pressure boiler context is 50 square feet. This specification is established to ensure safe operation and adequate heating capabilities for the boiler. The fusible plug serves as a safety feature that melts at a certain temperature to release pressure and prevent damage, and its effectiveness relies on the correct balance of heating surface area to manage the heat and steam production adequately. A surface area of 50 sq ft is considered a standard requirement that meets safety regulations and functional performance standards, ensuring that the boiler operates efficiently while being protected from potential overheating scenarios.
