Does a Fuel Oil Burner Have Requirements for Diesel Grades? Can You Use -50 Diesel Instead of 0 Diesel?

Fuel oil burners do have certain requirements for diesel grades. Diesel grades are mainly determined by their pour point (the temperature at which diesel begins to solidify in cold conditions). Different grades of diesel are suitable for different ambient temperatures.

Meaning of Diesel Grades

  • 0 Diesel: Suitable for environments with temperatures at 0°C and above. In colder temperatures, 0 diesel can solidify, leading to insufficient fuel supply or blockages in the fuel system.

  • -10 Diesel: Suitable for environments with temperatures at -10°C and above.

  • -20 Diesel: Suitable for environments with temperatures at -20°C and above.

  • -35 Diesel: Suitable for environments with temperatures at -35°C and above.

  • -50 Diesel: Suitable for environments with temperatures at -50°C and above. It has better low-temperature flow properties and is less likely to solidify.

Can They Be Used Interchangeably?

  • Burners Using 0 Diesel: These are typically designed and adjusted based on the physical properties of 0 diesel (such as viscosity, pour point, etc.). If the ambient temperature drops below 0°C, 0 diesel may start to solidify, leading to poor fuel supply and affecting the burner's normal operation.

  • Using -50 Diesel: -50 diesel has a very low pour point, meaning it remains fluid even at extremely low temperatures. However, since -50 diesel is more expensive to produce, it is usually only used in very cold regions or special situations.

Interchangeable Use

In environments above -50°C, it is possible to use -50 diesel instead of 0 diesel, as -50 diesel has better low-temperature flow properties and won't solidify in cold temperatures. However, consider the following points:

  • Cost: -50 diesel is more expensive, so using 0 diesel may be more economical when cold tolerance is not needed.

  • Burner Adjustment: If the burner was previously adjusted for 0 diesel, using a different diesel grade may affect combustion efficiency, so the burner might need to be adjusted to ensure it operates efficiently with -50 diesel.

Summary

In non-extreme cold environments, using -50 diesel instead of 0 diesel is feasible and won't damage the burner. The key is to choose the appropriate diesel grade based on the actual ambient temperature to ensure the proper operation of the fuel oil burner and economical use of fuel. In extremely cold environments, -50 diesel is the better choice to prevent fuel solidification issues.
