Thermal Oxidisers

Thermal oxidation is a well-established method for the treatment of contaminated process gases to meet IED (2010/75/EU) emission targets.

ERG offers systems to match project requirements, including:

Afterburners / Residence Chambers
Pyrolysis Chambers T > 650^o C
Precombustion Chambers T > 850^oC
Direct-fired oxidation up to 100% DRE (Destruction Removal Efficiency) (alternative methods of heat recovery available)
Recuperative thermal oxidation > 99% DRE and 75% heat recovery
Regenerative thermal oxidation 98% DRE and 95% heat recovery
Cooling systems to achieve: ambient temperature dew point < 850^oC
Post-combustion NOx abatement systems

ERG Systems Offer The Following Features:

Solid, Sludge, Liquid (aqueous / organic) and gaseous stream thermal destruction
Turndown capability up to 5:1 in ratio (out of ratio 10:1)
Process guarantees to cover TOC, CO, dust, dioxin and NOx emissions
Burner designs that use the stream as combustion air
Gas or liquid fuel fired system
Amine, halogen and sulphurous hydrocarbon destruction
Integrated systems for flue gas pollutant abatement

ERG designs its thermal oxidation systems for maximum Destruction Removal Efficiency (DRE) by ensuring:

ERG systems are designed in compliance with current and international engineering standards, including:

EN 746-1 – Common Safety Requirements for Industrial Thermoprocessing Equipment
EN 746-2 – Safety Requirements for Combustion and Fuel Handling Equipment
EN 298 – Automatic Gas Burner Control Systems
NFPA 82 – Standard on Incinerators
NFPA 86 – Standard for Ovens and Furnaces

Tray Selection

The materials of construction and tray design are matched to each application. It is typical for example, to use stainless steel trays with plastic or GRP vessels to give additional robustness.
