2025 ASME BPVC, Section VII: Recommended Guidelines for the Care of Power Boilers
The purpose of ASME Section VII, Recommended Guidelines for the Care of Power Boilers, is to promote safety in the use of power boilers. These guidelines are intended for use by those directly responsible for operating, maintaining, and examining power boilers.
With respect to the application of these guidelines, a power boiler is a pressure vessel constructed in compliance with ASME Section I in which, due to the application of heat, steam is generated at a pressure exceeding 15 psig (100 kPa) for use external to the boiler. The heat may be derived from the combustion of fuel (solids, liquids, or gases), from the hot waste gases of other chemical reactions, or from the application of electrical energy. The term power boiler in this Section includes stationary, locomotive, portable, and traction types, but does not include high-temperature water boilers or miniature boilers (Section I), nuclear power plant boilers (Section III), heating boilers (Section IV), pressure vessels (Section VIII), or marine boilers.
These guidelines apply to the boiler proper, pipe connections and piping up to and including the valve or valves as required by the Code, superheaters, reheaters, economizers, and appurtenances that are directly associated with the boiler.
Guidelines are also provided for operation of auxiliary equipment that affects the safe and reliable operation of power boilers.
Formulating a set of guidelines that is applicable to all sites and types of plants is difficult; therefore, it may be advisable to depart from these guidelines in specific cases. Manufacturer’s operating instructions should always be adhered to. Other industry-accepted codes and procedures, such as the National Fire Protection Association’s codes covering prevention of furnace explosions, are recommended for additional guidance.
