The purge table is a documented guideline that contains detailed information about the procedures to properly purge a boiler, including the specific steps to take, the times required, and the particular conditions necessary to ensure safety and efficiency during the purging process.

Adhering to this table is crucial for maintaining boiler safety, preventing explosive gas build-up, and ensuring effective operation. The information in the purge table provides a standardized method that operators must follow to mitigate risks and comply with industry standards.

While manufacturer’s instructions, safety regulations, and purge specifications also play important roles in the operation and safety of a boiler, the purge table specifically details the procedures that need to be followed for purging, making it the most direct and relevant source for this operation.
