Which ASME code contains recommended guidelines for the care of power boilers?

The correct answer is that ASME Section VII provides recommended guidelines for the care of power boilers. This section is specifically focused on the guidelines and practices for the maintenance, operation, and repair of boilers and pressure vessels. It addresses best practices to ensure safety, efficiency, and longevity of power boilers, which is crucial for the reliable operation of power generating systems.

ASME Section I, on the other hand, pertains to the construction of power boilers. It outlines the requirements for materials, design, fabrication, and inspection of power boilers but does not focus on their care after they have been constructed. ASME Section II contains rules for material specifications, while ASME Section IV deals with the rules for heating boilers, which are different from the guidelines applicable to power boilers. Each section has its own distinct focus and purpose, and understanding that Section VII is dedicated to the care of power boilers highlights its importance in the context of safe boiler operation.
