Effective treatment for high-energy waste streams: waste oil, sludge, and heavy fuel oils
ESI’s Thermal Oxidizer, also known as a Waste Oil Incinerator, is engineered for remote mining and industrial sites that generate hazardous liquid waste. The containerised thermal oxidiser effectively handles waste oil, heavy fuel oils, sludge and process residues from mining operations. The high-temperature combustion system safely destroys hydrocarbons and sludge, ensuring environmental compliance with minimal operator input.
Housed within a 20′ of 40′ shipping container, the incinerator is pre-assembled, pre-plumbed and wired for easy shipping to remote locations and requires minimal installation on site. Fully contained and built to withstand the elements, the container also provides shelter for the operators with awnings that open, once the unit is placed on site.
Advantages of ESI’s containerised incinerator system is that the units have been engineered for gas and oil industries, gold and copper mining, military and other secluded locations. The all-in-one containerised incinerators are easy to transport and install at remote sites with limited space and do not require additional shelter or construction.
Low Maintenance & Easy Operation
Our containerised incinerator features a sophisticated yet user-friendly design, ensuring easy operation and minimal maintenance for remote sites. Thermal oxidisers are widely used in industries for treating hazardous wastes, volatile organic compounds (VOCs), and other harmful pollutants, ensuring cleaner emissions and compliance with environmental regulations.

Thermal Oxidizer Combustion Process
A thermal oxidiser unit works by using high-temperature combustion to break down harmful organic compounds in waste streams, converting them into harmless byproducts like carbon dioxide and water vapour. Here’s how it operates step-by-step:
The unit uses high-temperature combustion to break down harmful organic compounds in waste oil.
- Waste Stream Entry: Waste oil or gaseous waste is pumped into the primary combustion chamber.
- Preheating: The waste stream is heated to the optimal temperature using a heat exchanger. This reduces the energy required for operation.
- Combustion: The waste is burned in a chamber at 750–1,200°C, converting harmful compounds into gases like CO₂ and H₂O vapour.
- Retention Time: Gases remain in the chamber for 0.5–2 seconds, known as a residence time, to ensure complete oxidation.
- Energy Recovery: Some thermal oxidisers include an optional heat recovery system to capture and reuse the heat generated during combustion, improving energy efficiency.

Factory Acceptance Test & Site Commissioning
We offer our clients a full Factory Acceptance Test (FAT), to view the assembled unit in action before the incinerator ever leaves the factory floor. We believe FATs are a crucial step in delivering high-performance, reliable systems.
During commissioning, we focus on improving on-site efficiencies by implementing tailored preset burn cycles, customise and reduce cycle lengths and enhance waste stream management.
Services Offered
ESI’s comprehensive range of services include:
- Site visits for waste stream assessment, recommendations and waste management proposals.
- Commissioning and operator training.
- Remote access control to the incinerator for assistance and any fault finding during the life of the unit.
- Preventative Maintenance program for 2- or 4-year fixed price servicing with ESI technicians, ensuring the unit runs optimally.
- Ongoing support including site visits and further training when required.
