D6 Virgin Fuel Oil (Mazut) is a heavy residual fuel oil widely used in industrial heating systems, power generation plants, marine boilers, and large-scale industrial operations. It is produced from the residue of crude oil distillation and is known for its high energy output, cost efficiency, and suitability for heavy-duty thermal applications.
D6 Virgin Fuel Oil, commonly referred to as Mazut, is typically used in facilities equipped with preheating systems due to its higher viscosity compared to lighter fuels. Its stable combustion characteristics and high calorific value make it an economical and reliable fuel source for industries requiring continuous heat and power supply.
This fuel is supplied according to international industrial fuel standards and is commonly traded in global energy markets for large-volume consumption.
