摘要:
Die Erfindung betrifft einen Regenerator-Wärmeübertrager (100) mit einem inneren ersten Ende (100a) und einem äußeren zweiten Ende (100b) und einer Mehrzahl von Wärmeübertrager-Blechen (110), die jeweils ein erstes und zweites Blech-Ende (100a, 110b) und einen in radialer Richtung gewölbten oder gekrümmten Blechabschnitt (116) aufweisen. Die Wärmeübertrager-Bleche (110) dienen dabei als Wärme-Speichermasse.

L'invention porte sur un conteneur (200) d'un système de stockage et de restitution de la chaleur, comprenant une enceinte comportant des moyens d'injection et de soutirage d'un gaz à refroidir ou réchauffer. L'enceinte est délimitée par une première enveloppe en béton (203) entourée par une couche isolante thermiquement (206), elle-même entourée d'une coque en acier (204). L'enceinte comporte au moins deux modules en béton (210) disposés l'un au-dessus de l'autre et centrés pour former la première enveloppe en béton (203), chaque module en béton comprenant un volume délimité par une paroi latérale en béton (211) et un fond perforé en béton (205), le volume contenant un lit fixe de particules d'un matériau de stockage et de restitution de chaleur (207).

The invention relates to a process and a system for the dry cleaning of waste gases containing pollutants of a combustion process by means of granular alkaline absorbents that absorb the pollutants of the waste gas. The invention also relates to a process and a system for feeding air to a combustion process and for the dry cleaning of waste gases containing pollutants of the combustion process by means of granular alkaline absorbents that absorb the pollutants of the waste gas. The direction of flow of the waste gases passed through the system is repeatedly changed, wherein in a first direction of flow the waste gases flow through first a first absorption region I, then a heating region and finally a second absorption region II, and, after switching over, the waste gases flow through first a second absorption region II, then the heating region (23) and finally a first absorption region I.

The invention relates to a method for operating a regenerator (1) for generating hot blast air for a steelmaking or steel treatment process, or a chemical process, wherein cold gas and hot gas is cyclically guided through a bulk material located in an annular space (4) between a hot grid (2) and a cold grid (3) surrounding the hot grid (2), and wherein a quantity of bulk material is removed from the annular space (4) in recurring cycles. The invention further relates to a regenerator. In order to achieve that on the one hand, the bulk material expanding during the hot phase does not deform and/or destroy the cold grid (3), and on the other hand, the bulk material particles do not get further eroded under alternating thermal stress, according to the invention during the phase of the cold gas application, or shortly before, or shortly thereafter, a defined quantity of bulk material determined by measuring means (20) is discharged from the bulk material through floor openings of the annular space (4).
