How Do Oil Stoves Work?

Published in Oil Heating Systems 2 mins read

Oil stoves generate heat by burning heating oil through a carefully controlled combustion process.

The basic operation of an oil stove involves delivering heating oil from a storage tank to a burner, where it is mixed with air and ignited to produce heat. This heat is then transferred to the surrounding space.

The Combustion Process in Detail

Understanding how an oil stove works means looking at the steps involved in converting liquid fuel into usable heat. Based on the principles of oil heating systems, this process typically includes:

  • Fuel Delivery: Heating oil is stored in a tank, usually located outside or in a basement. A pump draws the oil from the tank and sends it to the burner unit within the stove.
  • Fuel Preparation: Once the oil reaches the burner, it undergoes preparation for efficient combustion. This often involves heating the oil slightly and then forcing it through a nozzle under high pressure.
  • Atomization and Mixing: The high-pressure oil passing through the nozzle is atomized into a fine mist. This mist is then mixed with air. This fuel/air mixture is crucial for complete and efficient burning.
  • Injection: The prepared fuel/air mixture is then injected into the burner, specifically into the combustion chamber area.
  • Ignition: Inside the combustion chamber, an ignition source (like an electric spark or hot surface) ignites the fuel/air mixture. This creates a controlled flame.
  • Heat Generation: The burning of the oil in the combustion chamber produces significant heat.
  • Heat Transfer: The design of the oil stove allows this heat to be transferred to the stove's surfaces and into the room, warming the space. Exhaust gases from the combustion are safely vented outside, usually through a chimney.

Key Stages of Oil Combustion

Here's a simple breakdown of the core process:

  1. Oil travels from the tank to the burner via a pump.
  2. Oil becomes a fine mist mixed with air.
  3. The fuel/air mixture is injected into the burner.
  4. The mixture is ignited in the combustion chamber.
  5. Combustion generates heat.

This efficient process allows oil stoves to provide consistent and powerful heating for homes and other spaces.
