What is the maximum allowable oil pressure for low-pressure oil burners?

The maximum allowable oil pressure for low-pressure oil burners is indeed 15 psi. This standard is designed to ensure safe and efficient operation of the burner. Low-pressure oil burners typically operate under these limits to prevent issues such as leakage or inefficiency in combustion. If the pressure exceeds this limit, it may lead to complications like improper fuel atomization, which can affect the burner’s performance and may contribute to dangerous conditions such as spills or explosions.

The established standard of 15 psi balances the need for adequate fuel delivery while minimizing risks associated with higher pressure levels. Thus, understanding this limit is critical for operators to ensure both the safety and efficiency of the burner system.
