D6 Virgin Fuel Oil is a type of heavy fuel oil derived from petroleum distillation. It has a specific gravity of 0.930 to 0.970 and a kinematic viscosity of 12 to 20 cSt at 50°C. D6 fuel oil is mainly used in power plants and industrial boilers for the generation of steam and heat. It is highly combustible and has a relatively high calorific value, making it an efficient fuel source. In addition, D6 fuel oil has a low sulphur content, making it environmentally friendly and suitable for use in areas with strict emission regulations.
