1. Product Introduction & Main Application
Arnico’s Heavy Fuel Oil (Mazut M100) is a heavy, viscous, black residual fuel oil obtained from the bottom of atmospheric and vacuum crude oil distillation columns, conforming to the Russian GOST 10585-75 standard. This high-energy, economical fuel is the primary energy source for large industrial furnaces, thermal steam power plants, industrial boilers, and large oceangoing ships.

3. Features & Benefits
-
High Calorific Value: Supplies massive and stable energy for metal smelting, foundry, and cement production furnaces.
-
Fully Competitive Price: The most economical option among liquid fuels for energy-intensive industries.
-
Low Sulfur Grade Available: Allows for use in regions with stricter environmental regulations by reducing SOx emissions.
-
Even Atomization & Combustion: After proper preheating, it creates a stable spray pattern in industrial burners.
4. Industrial Applications
-
Thermal Power Plants: Fuel for boilers to generate superheated steam and drive steam turbines.
-
Metal & Steel Industry: Fuel for blast furnaces, preheating furnaces, and foundries.
-
Cement & Lime Industry: The primary fuel for rotary kilns in clinker production.
-
Shipping: Bunker fuel for large, slow-speed ocean-going vessel engines (requires pre-treatment).
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This material is not solid at ambient temperature but is highly viscous. At high temperatures, it releases toxic H₂S vapors. Prolonged skin contact causes severe irritation. The Arnico MSDS is mandatory.
-
Storage Conditions: Store in heated tanks equipped with heating coils and insulation, at a temperature of 40-60°C, to maintain pumpability. Water ingress into the tank must be strictly prevented (risk of violent boil-over and eruption).
-
Personal Protective Equipment (PPE): When handling, the use of full heat-resistant clothing, leather gloves, goggles, and a face shield is essential.
6. Quality Assurance & COA
Arnico Mazut M100 shipments are accompanied by a complete Certificate of Analysis (COA) detailing viscosity, density, and pour point.
