Flashcard on Combustion and Safety Devices

Front

What is a gravity flow, one-pipe system in oil heating?

Back

A system where fuel oil flows from the tank to the burner by the force of gravity, typically used when the oil tank is positioned above the burner.

Front

What does the acronym OSV stand for in oil heating?

Back

Oil Safety Valve, a device that prevents the release of oil in case of a malfunction.

Front

What tool is used to remove and replace nozzles in oil heating systems?

Back

A special nozzle wrench.

Front

What is the function of the cad cell relay in oil heating?

Back

It proves ignition by detecting light in the combustion chamber.

Front

What is the purpose of an oil deaerator?

Back

It allows a one-pipe system to function as a two-pipe system by removing air from the oil.

Front

What is the role of a nozzle in an oil burner?

Back

To atomize the fuel oil into a fine mist for efficient combustion.

Front

What safety function does an oil safety valve (OSV) serve?

Back

It prevents the flow of oil when the burner is not operating, ensuring safety.

Front

What is the significance of light detection in the combustion chamber?

Back

It indicates successful ignition and is monitored by the cad cell relay.

Front

How does a two-pipe system differ from a one-pipe system in oil heating?

Back

A two-pipe system allows for a return line, enabling better fuel management and efficiency.

Front

What are common signs of nozzle problems in oil burners?

Back

Inconsistent flame, excessive smoke, or poor heating performance.
