Fuel Oil
Fuel oil from used engine oil refining is a thick, black, and heavy liquid. It has high viscosity and density, and a high flash point above 250°C. It contains some water, ash, sulfur, and metals from engine wear. This fuel oil can be used in boilers, power plants, ships, and industries that need high heat. It is cheaper than many other fuels but needs careful handling because of pollutants. It helps recycle waste oil instead of throwing it away.

Fuel Oil Common Uses
| Application | Description |
|---|---|
| Industrial Boilers | Used as a heat source for generating steam or hot water in factories and plants. |
| Power Generation | Burned in large turbines or engines to produce electricity, especially in remote or backup sys |
| Marine Fuel | Used to power ship engines (bunker fuel), especially heavy fuel oil grades. |
| Heating (Commercial/Residential) | Used in furnaces and heaters for space heating in colder regions. |
| Asphalt Plants | Used as fuel to heat bitumen for road construction. |
| Cement Industry | Provides thermal energy for clinker production in rotary kilns. |
| Metal Processing | Used in foundries and smelters to supply high-temperature heat. |
| Brick and Ceramic Manufacturing | Used in kilns to fire bricks, tiles, and ceramics. |
