Under 46 CFR §63.01-3, an automatic auxiliary boiler with a heat input rating of 14,000,000 Btu/hr must have its automatic control system regulated under which part of Title 46?
- A. Part 63, because it is an automatic auxiliary boiler regardless of heat input
- ✓ Part 52 for the boiler and Part 62 for the control system, because the heat input rating equals or exceeds 12,500,000 Btu/hrCorrect
- C. Part 56 for the piping and Part 63 for the controls
- D. Part 63 for the boiler and Part 56 for the external piping only
Why B is correct
46 CFR §63.01-3(b) states that automatic boilers with heat input ratings of 12,500,000 Btu/hr (3.66 megawatts) and above must meet the requirements of Part 52, and their control systems must meet the requirements of Part 62. Part 63 governs automatic auxiliary boilers below that threshold.
