Mazut 100

Russian Fuel Oil Mazut M100 GOST 10585-75 or 10585-99 Mazut is a heavy, low quality fuel oil, used in generating plants. Mazut-100 is a fuel oil that is manufactured to GOST specifications, for example GOST 10585-75 or 99. (GOST is the Russian system of standards, much like ASTM, for example). Mazut is almost exclusively manufactured in the Russian Federation, Kazakhstan, Azerbaijan, and Turkmenistan. This product is typically used for larger boilers in producing steam since the BTU content is high. The most important consideration (not the only consideration) when grading this fuel is the sulfur content, which can mostly be affected by the source feedstock. For shipment purposes, this product is considered a ”dirty oil” product, and because viscosity drastically affect whether it is able to be pumped, shipping has unique requirements. Mazut is much like 6 Oil, and is part of the products left over after gasolighter components are evaporated from the crude oil. The main difference between the different types of Mazut-100 is the content of sulr. The grades are represented by these sulfuric levels: ”Very Low Sulr” is mazut with a sulr content of 0.5% ”Low Sulr” is a mazut with a sulr content of 0.5-1.0% ”Normal Sulr” is a mazut with a sulr content of 1.0-2.0% ”High Sulr” is a mazut with a sulr content of 2.0-3.5%
