What component meters the flow of fuel oil into the combustion chamber?

The nozzle is the component responsible for metering the flow of fuel oil into the combustion chamber. Its primary function is to atomize the fuel oil, breaking it into a fine mist, which allows for more efficient mixing with air and complete combustion. The nozzle is specifically designed to control the amount of fuel that is delivered, ensuring that the proper fuel-to-air ratio is maintained for optimal burning.

Additionally, the design and size of the nozzle contribute to the pattern and distribution of the fuel in the combustion chamber, which directly affects the combustion process and overall efficiency of the heating system. This level of precision is crucial for achieving high performance and reducing emissions from the oil burner.

In contrast to the nozzle, a pump’s role is to move fuel from the storage tank to the burner but does not directly meter the flow. A regulator controls pressure rather than flow quantity, and a filter’s purpose is to clean the fuel before it reaches the combustion system, ensuring that impurities do not affect performance.
