What is the typical result of a clogged oil filter in an oil burner?

A clogged oil filter in an oil burner typically leads to decreased fuel flow and potential burner shutdown. The oil filter is designed to trap impurities and debris within the oil before it enters the burner assembly. When the filter becomes clogged, it restricts the flow of fuel, causing a reduction in the amount of oil that can reach the burner. This shortage of fuel can result in poor combustion, causing the burner to operate inefficiently or even shutting it down altogether to prevent damage or unsafe conditions. The fuel flow must be sufficient to ensure proper burner operation and flame establishment; otherwise, the system may not function correctly, leading to potential operational issues and increased maintenance needs.
