What information can typically be found on a boiler's rating plate?

The rating plate on a boiler is a crucial component that provides essential information about the unit's specifications. It typically includes details such as the manufacturer's name, model number, and maximum operating pressure. This information is vital for a variety of reasons. Knowing the manufacturer and model helps in identifying the correct parts and service requirements for the boiler. The maximum operating pressure is particularly important for safe operation, as it indicates the pressure limits within which the boiler should function to ensure safety and efficiency. This data helps operators assess whether they are adhering to safety standards and enables them to make informed decisions regarding maintenance and operation.

The other options, while containing useful information, do not typically appear on the rating plate. The boiler inspection date and maintenance history often reside in service records rather than on the plate itself. The type of fuel used may be mentioned in documentation but is not usually found on the rating plate. Operating procedures and troubleshooting tips are typically included in the boiler's user manual or service documentation, rather than on the rating plate. Thus, option A encapsulates the critical and standardized information that is found on a boiler's rating plate.
