Massachusetts Oil Burner License Practice Test

What is the minimum operating pressure required for an oil pump?

1. 50 PSI

2. 75 PSI

3. 100 PSI

4. 125 PSI

The correct answer is: 100 PSI

The correct minimum operating pressure required for an oil pump is critical for ensuring effective and safe operation in heating systems. An oil pump must maintain adequate pressure to ensure that oil is delivered efficiently to the burner's nozzle, facilitating proper combustion. In heating systems that utilize oil burners, a minimum pressure of 100 PSI is generally required to overcome resistance within the system, such as pressure losses due to filters, valves, and piping. This pressure ensures that the oil reaches the burner at a sufficient flow rate, allowing for stable combustion and maximizing the efficiency of the heating system. If the pressure were too low, it could lead to incomplete combustion, soot production, and potential equipment failure. Understanding the required minimum pressure is essential for maintaining safety and efficiency in oil-burning heating systems, allowing technicians and operators to avoid issues related to improper oil supply and combustion performance.
