Between what temperatures must No. 6 fuel-oil be maintained in the storage tank?

No. 6 fuel oil, also known as bunker fuel, has specific temperature requirements for storage to ensure proper viscosity and usability in heating systems. Maintaining the fuel oil within the temperature range of 100°F to 130°F is critical for several reasons.

At these temperatures, the oil remains fluid enough to be pumped easily without excessive pressure on the system components, which can lead to operational issues. Keeping the oil at or above this minimum temperature prevents it from becoming too viscous, which could impede flow and hinder the operational efficiency of burners.

Furthermore, this temperature range is essential for effective atomization during the combustion process. If the fuel oil is not properly atomized, it can lead to incomplete combustion, higher emissions, and potentially damage the burner system. Thus, maintaining No. 6 fuel oil within the specified temperature range ensures optimal combustion, operational safety, and efficiency.
