Abstract
(DE)
Beim erfindungsgemäßen Verfahren zur selektiven katalytischen Entstickung bzw. Nutzung von staubhaltigen Abgasen soll eine von einem staubhaltigen Abgas durchströmte Behandlungseinrichtung (Katalysator, Abhitzekessel oder Wärmetauscher) vor Staub ablagerungen geschützt werden, wobei die Behandlungseinrichtung Oberflächenbereiche aufweist, die mit dem staubhaltigen Abgas in Kontakt kommen. Dabei wird der im Abgas enthaltene Staub vor dem Durchströmen der Behandlungseinrichtung elektrostatisch aufgeladen und die mit dem staubhaltigen Abgas in Kontakt kommenden Oberflächenbereiche werden auf einem Potential gehalten, das zum Potential des aufgeladenen Staubes gleichgerichtet ist.
(EN)
In the method according to the invention for the selective catalytic denitrogenization or utilization of dust-containing exhaust gases, it is sought to prevent dust accumulations in a treatment device (catalytic converter, waste heat boiler or heat exchanger) through which a dust-containing exhaust gas flows, wherein the treatment device has surface regions which come into contact with the dust-containing exhaust gas. Here, the dust contained in the exhaust gas is electrostatically charged before it flows through the treatment device, and those surface regions which come into contact with the dust-containing exhaust gas are held at a potential with the same polarity as the potential of the charged dust.
(FR)
L'invention concerne un procédé de dénitruration catalytique sélective ou d'utilisation de gaz de combustion contenant des poussières, selon lequel un dispositif de traitement (catalyseur, chaudière à récupération ou échangeur thermique) parcouru par un gaz de combustion contenant des poussières est protégé contre les dépôts de poussières, le dispositif de traitement présentant des zones de surface entrant en contact avec les gaz de combustion contenant des poussières. Les poussières contenues dans le gaz de combustion sont chargées électrostatiquement avant de parcourir le dispositif de traitement et les zones de surface entrant en contact avec les gaz de combustion contenant des poussières sont maintenues à un potentiel aligné sur le potentiel des poussières chargées.
