Regenerative (thermal) afterburning is an exhaust air purification system using oxidation and integrated heat recovery for process exhaust air preheating.
Depending on the process or clean gas requirements, working temperatures of 650...900 °C are achieved in the RNV combustion chamber with corresponding residence times.
Like the TNV process, regenerative afterburning is an air-hygienically optimal process, since the exhaust air is completely converted into the harmless substances water (H2O) or carbon dioxide (CO2). Regenerative post-combustion plants offer a great deal of savings potential through integrated heat and energy recovery for the process air, whereby the energy costs to be used are minimised or, in autothermal processes, reduced to the use of electrical energy.
The "regenerative afterburning" process is particularly recommended for higher exhaust air volume flows and for processes in which no further generation of process heat (warm/hot water, thermal oil, steam) is required. Our regenerative post-combustion plants are specially adapted to each customer process and can also be subsequently adapted or extended to other processes. Our RNV plants are specially designed and adapted to the customer's installation site, whereby a cost-effective and effective exhaust air cleaning can be realised even in confined and minimal space conditions.
