Heavy Fuel Oil / MAZUT M100 (GOST 10585-75)

There are four distinct grades of mazut fuel oil  Very Low Sulfur, Low Sulfur, Normal, and High Sulfur  which range between 0.005 and 0.035 in sulfur content. The amount of sulfur affects how clean the oil burns, and in turn the emissions it creates, and the amount of buildup that accumulates within the engines and furnaces that burn it

Mazut 100 prices are often determined by its point of origin and mode of production. Aside from shipping factors duties, regulations, and the like  this also relates to the quality of the product itself. Mazut comes in a variety of grades, ranging from “Very Low Sulfur” to “High Sulfur”, which each offer a range of sulfur content from one-half to three and a half percent respectively. The former sort of mazut is fairly uncommon outside of Russia or the Commonwealth of Independent states. This is because it relies upon a crude source with low sulfur, and its relatively difficult production process.
