Fuel oil, also called kerosene, home heating oil, diesel fuel or coal oil, is used to power various kinds of engines, lamps, heaters, stoves and lanterns. It is also stored in compact vessels for use in space heaters and used to clean metal components.
The burnable liquids produced from crude oil are called fuel oils. Fuel Oil No. 1 is commonly known as kerosene, while Fuel Oil No. 2 is typically called home heating oil. The diesel fuel used to run boats is called Fuel Oil No. 4. Examples of diesel fuels are fuel oils 1-D and 2-D.
Fuel oil is one of the typical options of homeowners for running home heating equipment, such as furnaces and boilers. The thermostat transmits an electrical signal to the furnace whenever the room temperature decreases. The furnace provides fuel to the burners, which burn fuel oil to produce a flame, and causes fuel ignition. The heat exchanger, a metal component of the burners, becomes hotter, and heat is transferred to the surrounding air. The timer-operated blower then starts to move air through the furnace heating system.
Boilers also supply hot water besides heating the home. Some of the types of boilers that use fuel oil are hot water boiler systems and steam boiler systems.
