Mazut
A heavy, viscous fuel oil used primarily in industrial applications and power generation.

Overview
Mazut is a heavy, viscous fuel oil that is a byproduct of petroleum refining. It is characterized by its high viscosity and dark color. Mazut is primarily used in industrial boilers, power plants, and as a feedstock for further processing into lighter fuels. It requires preheating before use due to its high viscosity.
