Title:
SYSTEM AND METHOD FOR PREDICTING WEAR OF POWER-GENERATING BOILER TUBE
Document Type and Number:
WIPO Patent Application WO/2019/088368
Kind Code:
A1
Abstract:
A system for predicting wear of a boiler tube according to an embodiment of the present invention comprises: a fuel property database which provides information about the properties of fuel that is currently being combusted in a power plant, and which stores a wear trend index of the fuel that is calculated using the information about the fuel properties; an operation data-linked combustion interpretation device which calculates information on the state of a high temperature unit of the boiler using information received from the fuel property database, and operation data of the power plant as input values; a cold flow distribution measurement database which stores local velocity distribution data inside the boiler that is measured for each cross section of the boiler; an actual local velocity calculation device which calculates an actual velocity for each local position with respect to the respective cross sections of the boiler, using the information on the state of the high temperature unit of the boiler and the local velocity distribution data inside the boiler; and a boiler local wear prediction device which predicts wear trends for each local position with respect to the respective cross sections of the boiler using the wear trend index, the information on the state of the high temperature unit of the boiler, and the local velocity distribution data inside the boiler.
