Iran Fuel Oil CST-380 / Mazut
fuel oil is defined as any liquid that is burned in furnaces, boilers or used in a power generation engines. Fuel oil is obtained from distilled crude oil having a flash-point of approximately 40 ° C. According to this definition, diesel is a type of fuel oil.
Fuel oil is composed of long hydrocarbon chains, particularly alkanes, cycloalkanes and aromatics and placed in the classification of heavy industrial fuels, heavier than gas-oil and Naphtha.
Fuel oil (also known as heavy oil, marine fuel or furnace oil) is a fraction obtained from petroleum distillation, either as a distillate or a residue. Broadly speaking, fuel oil is any liquid fuel that is burned in a furnace or boiler for the generation of heat or used in an engine for the generation of power, except oils having a flash point of approximately 42 °C (108 °F) and oils burned in cotton or wool-wick burners.
