A burner is a device that burns liquid fuel. The fuel, such as fuel oil, diesel or home heating oil, is usually a fine spray forced through a nozzle under pressure. The spray is ignited along with air that is forced through by an electric fan. The fuel can also be burnt in other ways, for example, by vapourising the oil on a hot plate.
You will find burners in many applications including industrial oil heaters and boilers.
