摘要:
The present invention relates to a system (10) for regenerative thermal oxidation, and to a method for operating such a system (10). The system (10) comprises a group of regeneration chambers (14, 16, 8, 20) having at least four regeneration chambers, each provided with a heat exchanger, and, by way of valves, are connected to a supply line for switchably feeding a crude gas stream (22, 30), to a discharge line for discharging a purified gas stream (26, 34), and to a rinsing system. The system (10) is provided with a combustion chamber having a combustion space (12), by way of which the regeneration chambers (14, 16, 8, 20) of the group of regeneration chambers (13, 16, 18, 20) are interconnected. The system (10) is provided with a control unit for opening and closing the valves. When operating the system (10), a crude gas stream (22, 30) is introduced by way of the supply line, and a purified gas stream (26, 34) is discharged by way of the discharge line.
摘要:
The invention relates to a method for oxidizing gases containing fuel-nitrogen compounds (BSV) while generating low levels of nitrogen oxides. More precisely, the invention relates to methods in which the exhaust gases containing fuel-nitrogen compounds are converted into exhaust gases containing nitrogen oxides in a first step and said gases containing nitrogen oxides obtained in such a way are mixed with exhaust gas containing fuel-nitrogen compounds that has not been converted and then are treated under reductive conditions in order to reduce the nitrogen oxides in the exhaust gas. The invention further relates to a system or a device that makes it possible to oxidize exhaust gases containing fuel-nitrogen compounds while generating low levels of nitrogen oxides.
