The invention relates to an apparatus for accommodating bulk material. The apparatus has a bulk material receptacle (1') and contains a discharge device. The bulk material receptacle (1') has a bottom (6) having a discharge opening (5) and has a jacket wall (8). The discharge device comprises a clearing element (2) supported on a bearing column (4) so as to be rotatable about a center axis (4') that passes through the discharge opening (5) and comprises a damming cone (7) arranged above the bottom (6). The damming cone (7) and the jacket wall (8) and/or the bottom (6) form a discharge gap (9). The apparatus contains a drive (17) for the clearing element (2), by means of which the clearing arm (2) can be rotated about the center axis (4') in a working direction of rotation (17'). At least one clearing prong (3) is fastened to the at least one clearing element (2). When the clearing element (2) rotates about the center axis (4') in the working direction of rotation (17'), the at least one clearing prong reaches into the bulk material (26) accommodated in the bulk material receptacle (1') and pushes the bulk material (26) to the center axis (4'), wherein the bulk material (26) falls through the discharge opening (5) of the bottom (6). According to the invention, the damming cone (7) extends over the clearing arm (2). Alternatively or additionally, the bottom (6) can be designed as a diffuser bottom extending to the discharge opening (5) in a rising manner.

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.

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.
