Odret (Direct Fired Incinerator)
06 Aug, 2018 / 1120 Views
Odret was built on our vast experience as a paint plant manufacturer, and hundreds of these facilities are now in operation around the world.
It can handle gases with any component and concentration, and oxidize and decompose almost every harmful or malodorous component with a high treatment efficiency and consistency.

Exhaust gas treatment with Odret:
- Uniformly heats a harmful or malodorous gas at 750°C or higher.
- Occurs when a target gas remains in the reactor for 0.5 seconds or longer.
In general, when treating an exhaust gas from the production process with only its oxidative decomposition energy for combustion, the concentration of the gas is not high enough to maintain the necessary temperature level in the reactor (750°C ). Therefore, some fuel is required, however its cost is saved with the heat exchange between an oxidized and decomposed gas and the next untreated gas (heat transfer efficiency = 75% max.)
Features of Odret
Consistent treatment
Treatment temperature can be easily adjusted based on the components in the exhaust gas, enabling consistent treatments. The exhaust gas components are fully treated with combustion.
High deodorization efficiency
Malodorous components are directly burned, decomposing and removing foul odors completely.
The exhaust gases containing silicon (Si), phosphorus (P), and sulfur (S), as well as gases containing tar, dust, mist, and metal vapors (Sn, Pb, and Hg) can also be treated.
Economic efficiency with utilization of waste heat
When heat is required for purposes other than pre-heating untreated gases, two heat exchangers are installed, one for heating untreated gases and the other for transferring extracted heat. For this application, heat exchangers with various heat recovery rates can be paired.
Easy to maintain
Odret can easily be operated in full-automatic mode. Replacement of the catalyst is not required.
Optimal burner
The most appropriate burners are selected based on our vast experience and technologies. City gas, LPG, and lamp oil can be used as fuel.
