What effect does low pressure have on an oil burner’s efficiency?

Low pressure in an oil burner often leads to decreased efficiency. This is primarily because oil burners are designed to operate optimally at specific pressure levels. When the pressure is too low, it can result in incomplete combustion of the fuel. Incomplete combustion means that not all of the oil is being burned effectively, which can lead to a buildup of soot and other byproducts that not only waste fuel but can also negatively impact the burner’s performance.

Additionally, low pressure can affect the atomization of the fuel. Proper atomization is essential for ensuring that the oil is broken down into fine particles so it can mix with air adequately and combust thoroughly. If the atomization is poor due to insufficient pressure, less efficient combustion occurs, leading to a reduction in the overall efficiency of the burner.

Therefore, maintaining the appropriate pressure levels is critical for ensuring that oil burners operate efficiently and effectively, making decreased efficiency the clear impact of low pressure in this context.
