Title:
METHOD FOR TREATING EXHAUST GAS OF THERMAL POWER PLANT BY USING ARTIFICIAL INTELLIGENCE, AND DEVICE FOR TREATING EXHAUST GAS OF THERMAL POWER PLANT BY USING ARTIFICIAL INTELLIGENCE
Document Type and Number:
WIPO Patent Application WO/2022/145812
Kind Code:
A1
Abstract:
Provided are a method for treating exhaust gas and a device for treating exhaust gas of a thermal power plant by using artificial intelligence. The method for treating exhaust gas comprises: (a) a learning-derivation step in which a computer learns the correlation between pre-collected operation data and exhaust gas composition data of a sample gas turbine by means of an artificial intelligence learning algorithm so that an influence factor affecting the concentration of at least one pollutant in exhaust gas is derived; (b) a learning-prediction step in which the computer learns, by means of the artificial intelligence learning algorithm, the correlation over time between a change in the influence factor measured in real time during gas turbine operation and a change in the concentration of at least one pollutant in the exhaust gas, so that, at a first time point, the concentration of at least one pollutant in the exhaust gas at a second time point, which elapses after the first time point, is predicted; and (c) a target-control step of calculating a reducing agent injection amount corresponding to the concentration of at least one pollutant in the exhaust gas at the second time point predicted in step (b), and controlling a reducing agent transfer process from the first time point so that the amount of reducing agent injected into the exhaust gas matches the reducing agent injection amount calculated at the second time point.
