A METHOD FOR AUTOMATICALLY CONTROLLING PRECISE DOSAGE RATE OF CONDITIONING CHEMICALS FOR A FLUE GAS STREAM INPUT OF ELECTROSTATIC PRECIPITATOR

摘要

A method of predicting the precise rate of dosage of specified chemicals and/or their compounds and/or steam to a flue gas stream from coal combustion and/or thermal processors before electrostatic precipitator to optimize the rate of dosage resulting in control and reduction of emission from the stack preventing excess dosage in economical manner. The predetermined dosage rate of the specified chemicals will be used for online control dosage using a control system. This method is designed to avoid any excess dosage of the specified chemicals and/or their compounds and thus reduce the emission from the stack economically.
