What safety device is commonly used to prevent oil leaks in a burner system?

The commonly used safety device to prevent oil leaks in a burner system is the fuel shut-off valve. This device plays a crucial role by automatically stopping the flow of fuel oil to the burner in the event of an abnormal condition, such as pressure drops or system malfunctions. By doing so, it effectively minimizes the risk of fuel leakage, which can lead to hazardous situations such as fires or environmental contamination.

In addition to its primary function of leak prevention, the fuel shut-off valve is designed to enhance the overall safety and efficiency of the burner system. It works in conjunction with other safety devices, helping to ensure that fuel is only present in the system when conditions are safe for combustion. This makes it a fundamental component in maintaining safe operations in oil-burning systems.
