EPRICON: Agentless Flue Gas Conditioning For Electrostatic Precipitators

摘要

Achieving efficient particulate control in coal burning electric utility plants is becoming an increasingly difficult proposition, given the variety of regulatory, technical, operating and environmental pressures that exist in the U.S. For most powerplants, particulate control is achieved by an electrostatic precipitator (ESP). Under optimal conditions, modern ESPs are capable of achieving particulate removal efficiencies of 99.7% and higher... well within the regulatory levels prescribed by the Clean Air Act. Unfortunately, optimal conditions are not always present. ESPs are sensitive to flue gas conditions, and those conditions may change dramatically after a fuel switch or the installation of some types of emissions control technology upstream of the ESP.
