Under which section of the ASME is the care and operation of heating boilers addressed?

The care and operation of heating boilers is specifically addressed in Section IV of the ASME Boiler and Pressure Vessel Code. This section outlines the rules for the construction of heating boilers which are utilized for low-pressure systems, including guidelines on design, materials, workmanship, and testing.

Section V deals with nondestructive testing, which is essential for ensuring the integrity of pressure vessels but does not cover operational guidelines. Section VI typically pertains to the care of boiler feedwater and small heating boilers specifically, but it does not encompass the overall care and operation principles that Section IV provides. Section VIII is focused on the design and fabrication requirements for pressure vessels that operate at higher pressures, which is outside the scope of low-pressure heating boiler operation and care.

Therefore, understanding the regulations referenced in Section IV ensures proper compliance and safe operational practices for heating boilers, making it the appropriate section to consult for matters pertaining to the care and operation of these systems.
