A safety device for an oil fired boiler

摘要

An oil supply safety device (1) includes a buffer tank (3) having an inlet (10) through which oil is delivered from an oil storage tank and an outlet (12) for delivery of oil to a burner of a boiler. A water level sensor (18) within the buffer tank (3) detects when water removed from the oil and collected in the buffer tank (3) rises to a predetermined level. The sensor (18) is connected to a controller (2) which is operable to shut off electrical supply to the oil fired burner of the boiler to stop the burner in response to the water level in the buffer tank (3) reaching the level sensor (18).
