Dynamic virtual system for analyzing and preventing boiler heating surface failure area

Abstract

The invention provides a dynamic virtual system for analyzing and preventing a failure area of a boiler heating surface. Based on working characteristics of failure prevention of a coal-fired power plant boiler heating surface, the invention adopts computer virtual reality techniques to create a boiler body heating surface failure analysis prevention and dynamic virtual simulation system. By a graphics workstation of a computer, computer virtual simulation is made on the boiler heating surface. A computer boiler heating surface virtual digital platform is created. boiler base metal defect data, installation data, furnace tube physical attribute data, failure historical data, maintenance data and online operation state data are collected. Meanwhile, the system is integrated with an equipment management system and production process control in a power plant. Through data mining, classification, calculation and analysis, the easy-to-fail parts of the boiler heating surface are predicted,and computer analogue simulation is carried out on the positioned easy-to-fail parts to understand related damage caused by leakage of different parts, so that preventive measures are established, andthe failure accident rate of the boiler heating surface is reduced.

Description

technical field [0001] The invention relates to the field of failure prevention and control of the heating surface of a boiler body of a coal-fired generating set, in particular to a dynamic virtual system for analyzing and preventing the failure area of ​​the heating surface of the boiler. Background technique [0002] The failure of the heating surface of the coal-fired generator boiler has a serious impact on the safety production and economic benefits of the power plant. Therefore, avoiding the failure of the boiler heating surface is not only a key countermeasure part of the boiler professional, but also an important item in the metal technical supervision work. It is the key management link of power plant safety production. [0003] Coal-fired generating set boilers cover a wide range of heating surfaces, and the spatial structure is also extremely complex. The material distribution and working conditions of each part are also different. The causes, mechanisms and meth...

AI Technical Summary

Problems solved by technology

[0006] (1) The spatial location of hidden dangers and leakage areas is not clear, and the data of defects and hidden dangers are discrete, making it difficult to analyze and trace;

[0007] (2) The history and real-time data of boiler operation have not been established for correlation calculation and analysis;

[0008] (3) Anti-wear and explosion-proof three-dimensional monitoring can only realize the monitoring of the current temperature state under the three-dimensional structure of the boiler, without data analysis, mining and calculation, it is impossible to predict and analyze the prone parts of the boiler leakage
