The specific regenerative thermal oxidizers for deodorisation are afterburners specifically built to reduce the odorous load in a gaseous effluent.

Features and advantages

  • Electrical switchgear with PLC and remote assistance
  • Independent combustion system to guarantee correct operation of the plant
  • Modulating combustion system to maintain the correct operating temperature with the different incoming pollutant loads
  • Oversized combustion chamber, refractory interior with high density ceramic fibre insulation, allowing the plant to last longer working at temperatures higher than standard.
  • Enhanced valve tightness rating
  • High purification efficiency (>99.5%)
  • High thermal efficiency (92-96%)
  • Reduced production of secondary pollutants (CO, NOx)
  • Possibility of further heat recovery
  • Easy to manage and use
  • Reduced maintenance

Operating principle

The specific regenerative thermal oxidizers for deodorisation are afterburners specifically built to reduce the odorous load in a gaseous effluent.

The odorous load in a gaseous stream normally consists of thousands of organic compounds of various nature and in a very small quantity, insofar as their concentration sometimes hardly reaches a few tenths of a milligram.

The problem with these pollutants is their reduced olfactory threshold, which together with their unpleasant smell can lead to odour nuisance.

The most invasive solution to this problem regards the installation of a regenerative thermal oxidizer with measures to enhance the purification effect:

  1. oversized combustion chamber to increase the time the pollutants are retained inside and their turbulence
  2. higher than standard operating temperature in chamber
  3. increase of tightness of process valves to avoid pollutant leakage and therefore odour

All of these details, as well as adopting the regenerative exchanger, which reduces the consumption of fuel, provide a more complete, appropriate and invasive solution to permanently resolve the problem of high odorous loads.

Lastly we must point out that the reduction of odorous pollution only regards the reduction of organic pollutant concentration and not the odour caused by inorganic pollutants.

Plant engineering solutions

The operation of this machine is absolutely the same as that described for the three (or more) column regenerative thermal oxidizer.

For these plants, special attention is given to the size and shape of the combustion chamber as well as to the turbulence which must be created to maximize pollution control efficiency which must then be proportional to the suppressed odorous load.

Pollution control efficiency is maximised by using special almost perfectly airtight valves.
