Abstract

Es wird ein Heizkessel mit einem in einem Abgasströmungskanal vorgesehenen elektrostatischen Abscheider beschrieben, der eine im Abgasströmungskanal angeordnete Sprühelektrode und eine durch die Kanalwände gebildete Kollektorelektrode umfasst. Um den Abreinigungsgrad des elektrostatischen Abscheiders zu verbessern, wird vorgeschlagen, dass innerhalb des Abgasströmungskanals über die Kanallänge verteilt Strömungsbleche vorgesehen sind, die sich zur Kanalachse geneigt über den Kanalquerschnitt erstrecken und die Sprühelektrode aufnehmende Strömungsöffnungen für die Abgase aufweisen.

Figure imgaf001
There is described a boiler having an electrostatic precipitator provided in an exhaust gas flow passage, which includes a discharge electrode disposed in the discharge electrode and a collector electrode formed by the channel walls. In order to improve the Abreinigungsgrad of the electrostatic precipitator, it is proposed that distributed within the exhaust gas flow channel over the channel length flow plates are provided which extend inclined to the channel axis over the channel cross-section and the spray electrode receiving flow openings for the exhaust gases.
