How are fuel oil strainers normally configured in a system?

Fuel oil strainers are typically configured in a system to ensure that the oil is clean and free of contaminants before it reaches the burner. The common practice is to have one strainer at the suction side of the pump, which filters out larger particulates and debris as the fuel oil is drawn from the storage tank. This initial filtration is crucial as it protects the pump and prevents clogging of the system.

In addition to the suction side strainer, having another strainer positioned just before the burner provides a second layer of filtration. This additional measure ensures that any remaining impurities that might have escaped the first strainer are caught before the oil is combusted. This two-step filtration process enhances the overall efficiency and reliability of the operation, reducing the risk of burner malfunctions and contributing to a cleaner combustion process.

This configuration aligns well with standard practices in fuel oil systems, where dual filtration helps maintain system integrity and reduces maintenance needs.
