The oil storage tank provides oil for combustion in the oil burner. This oil serves as a fuel that, when ignited, produces heat for various heating applications, such as residential and commercial heating systems. The oil is drawn from the tank and pumped into the burner, where it is atomized and mixed with air to create an efficient flame for combustion.

Oil, specifically used in heating applications, is a hydrocarbon-based fuel that has a high calorific value, making it effective for generating heat. Other substances mentioned in the options, such as gas, air, and water, play different roles in combustion processes but do not serve as the primary fuel source in an oil burner context. Gas can be another type of fuel for combustion, air is necessary for the combustion reaction to occur, and water is typically not used for combustion in this scenario but may be relevant in other applications such as heat exchange.
