Massachusetts Oil Burner License Practice Test

What is the purpose of delayed opening oil valves?

1. To reduce oil consumption

2. To allow oil pump to come up to speed

3. To maintain oil temperature

4. To prevent backflow of oil

The correct answer is: To allow oil pump to come up to speed

The purpose of delayed opening oil valves is to allow the oil pump to come up to speed before enabling the flow of oil into the burner. This is crucial because if the oil is allowed to flow into the combustion chamber too quickly without the pump operating at optimal speed, it could lead to incomplete combustion. Delayed opening ensures that the oil pump has reached an adequate pressure and flow rate, which helps maintain efficiency and safety in the oil burning process. Having the pump at the right speed also helps to avoid potential issues such as flooding the combustion chamber with oil before there is sufficient air mixed in for combustion. This process facilitates proper mixing of oil and air, optimizing the burner’s operation and enhancing overall performance while mitigating risks associated with improper combustion.
