Why is proper combustion air vital for an oil burner?

Proper combustion air is vital for an oil burner because it is necessary for complete fuel combustion. When an adequate amount of combustion air is supplied, the oil can burn efficiently and entirely. This leads to optimal energy production, as the fuel is fully consumed and converted into heat energy. Insufficient combustion air can result in incomplete combustion, which not only wastes fuel but also produces harmful emissions, including carbon monoxide and unburned hydrocarbons. These byproducts can be dangerous and lead to increased pollution levels. Ensuring that the proper air-to-fuel ratio is maintained is crucial for the safe and efficient operation of an oil burner system.
