Burning oil is a complicated process that requires specialized equipment and experience. Depending on the type of oil you are trying to burn, you will need to choose a specific burner to ensure proper and safe combustion. For example, if you are burning waste oil, a multi-fuel burner is recommended. This type of burner is designed to burn a variety of fuel sources, including waste oil, diesel, kerosene, fuel oil, and vegetable oil. Additionally, it is important to select a burner that can accommodate the necessary BTU output for the size of your space. Finally, safety should be a top priority. Make sure to use a burner that is certified for use in your area and is equipped with the necessary safety controls, such as over-temperature shut-off.
