  • Method of operating a catalytic converter
    Patent number: 6365119
    Abstract: Constantly high efficiency of a catalytic converter can only be ensured when the configuration is maintained relatively free of particulate matter. A screen is disposed on the inflow side of the catalytic converter, which continuously or discontinuously transports away the flue dust particles collected by the screen. The flue dust collected is transported by the lateral movement of the screen to one side of the catalytic converter where the collected dust is removed. Alternatively or additionally, a vacuum system may be employed to clean the screen.
