What is the formula for sizing nozzles for oil burners using output BTUs?

The formula for sizing nozzles for oil burners is determined by dividing the output in BTUs by 112,000. This formula is based on the relationship between the amount of oil that the burner can efficiently combust and the energy content of the oil being used.

By applying this formula, technicians are able to calculate the appropriate nozzle size needed to ensure that the burner operates effectively at the specified output. This ensures that the burner receives the correct amount of fuel to produce the required heat output without causing efficiency loss or incomplete combustion. Additionally, using the correct nozzle size can help optimize system performance, reduce emissions, and maintain safety standards within the heating system.

The other options do not align with the established formula and would lead to incorrect sizing of the nozzles, potentially resulting in inadequate heating or wasted fuel.
