USCG Exam PracticeBoiler and steam propulsion fundamentals
Under 46 CFR §63.01-3, an automatic auxiliary boiler with a heat input rating of 14,000,000 Btu/hr must meet the requirements of which subchapter for its construction, and which part for its control system?
- A. Part 63 for construction; part 62 for controls
- ✓ Part 52 for construction; part 62 for controlsCorrect
- C. Part 52 for construction; part 63 for controls
- D. Part 63 for construction; part 63 for controls
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 of the subchapter, and their control systems must meet the requirements of part 62. A 14,000,000 Btu/hr boiler exceeds the 12,500,000 Btu/hr threshold, so part 63 does not govern its construction or controls. (46 CFR §63.01-3)
