Once every how many hours of boiler operation must burner barrels be hydrostatically tested?

Burner barrels must be hydrostatically tested every 18 to 20 hours of boiler operation to ensure their integrity and safety. This testing is crucial because it assesses the strength of the burner barrels under high pressure and helps identify any potential leaks or weaknesses that could lead to catastrophic failures during operation. The specified interval of 18 to 20 hours is based on operational standards aimed at maintaining safety and reliability in boiler systems. By frequently testing the components, operators can mitigate risks and ensure the continued efficient operation of the boiler, adhering to best practices within the field.
