What part prevents fluid leakage from the oil burner?

The part that prevents fluid leakage from the oil burner is the oil seals or gaskets. These components are crucial in creating a tight seal between different parts of the burner assembly, ensuring that oil does not escape during operation. Proper sealing is essential for maintaining efficiency and safety in the operation of the oil burner; if these seals or gaskets are worn or damaged, it can lead to leaks, which not only decreases efficiency but can also pose fire hazards and environmental risks.

Other components mentioned, such as the fuel filter, oil pump, and burner head, play significant roles in the burner’s operation, but they are not primarily designed to prevent fluid leakage. The fuel filter is primarily focused on removing impurities from the oil, while the oil pump is responsible for moving the oil through the system. The burner head is where combustion occurs and does not function to seal the system against leaks. Thus, the effective sealing provided by oil seals or gaskets is vital to the overall safe and efficient operation of the oil burner.
