What provides the supply of oil for combustion in an oil burner?

The supply of oil for combustion in an oil burner comes from the storage tank. The storage tank is where the oil is stored before it is transported to the burner for combustion. It serves as the reservoir for the fuel that is necessary for the operation of the oil burner.

While the oil pump plays a crucial role in moving the fuel from the storage tank through the fuel line to the burner, it relies on the oil being present in the storage tank. Without the tank, there would be no fuel available for the pump to distribute. Other components like the ignition system are also essential to the operation of the burner, but they do not provide the oil itself; instead, they assist in igniting the oil once it is delivered to the burner from the storage tank.

Understanding the function of the storage tank clarifies its critical role in the overall functioning of the oil burner system.
