Abstract

A process for the in-situ transformation of chemical species present in the flue gas to form sulfur trioxide, wherein the fly-ash particles are conditioned by altering their surface electrical properties. More specifically, the subject invention is concerned with fly ash conditioning using plural lamps located at specific positions in a specific arrangements most advantageous to the chemical conversion that would take place. The novel invention conditions flue gas emissions by treating the flue gas with SO.sub.3, where the SO.sub.3 is generated in the flue gas by photocatalytic conversion of SO.sub.2 using selectively spaced and arranged ultra violet light emitting lamps and related automated components. A preferred embodiment of the invention describes the novel process with a large-scale flue gas emission plant having an electrostatic precipitator(ESP) and flue gas stack where a novel feedback control system operates the various UV lamps by measuring power output of the ESP and an op
