Abstract
An integrated SCR ESP employs catalytic collector plates for NO.sub.x and particulate removal. Ammonia injected either directly in the ESP or upstream therefrom catalytically reduces NO.sub.x to nitrogen and water. The excess ammonia assists in capturing particulates in the ESP. This prevents problems of ammonia slippage. The SCR catalytic collector plates are positioned in at least one field of the ESP and preferably in at least the first field.
