Embodiment 1

[0059] Such as figure 1 As shown in the present invention, a method for advanced diagnosis and analysis of the main heating surface of a boiler, it first adopts the organic integration of theoretical mathematical model, dynamic expert knowledge base and data mining to establish an intelligent advanced diagnosis model, and then adopts the means of three-dimensional visualization The internal structure of the boiler is displayed, and finally the predicted damage to the main heating surface of the boiler is adjusted and analyzed, and the intervention adjustment after the advanced diagnosis of the main heating surface of the boiler is carried out to form a closed-loop management, so as to avoid the occurrence of boiler failure.

Embodiment 2

[0061] Such as figure 2 As shown, a method for advanced diagnosis and analysis of the main heating surface of a boiler of the present invention specifically comprises the following steps:

[0062] (1) Establish a mathematical model: obtain the data information of the real-time monitoring points of the boiler, establish a mathematical model of the main damage types of the heating surface of the boiler, and perform quantitative calculation and analysis of inferior damage to obtain the real-time damage of the main heating surface of the boiler;

[0063] (2) Establish a dynamic expert knowledge base: collect and organize the general theoretical knowledge for the four-tube failure of the diagnosed boiler and the historical maintenance data of the diagnosed boiler, and summarize it to obtain an expert knowledge base related to the four-tube failure of the diagnosed boiler. The expert knowledge base reserves the expert knowledge acquisition interface, constantly updates the expert k...

Embodiment 3

[0091] Such as image 3 Shown, a kind of boiler main heating surface advance diagnosis analysis system of the present invention, it comprises:

Abstract

The invention discloses a method and system for the advanced diagnosis and analysis of the main heating surface of a boiler. The method includes the steps of firstly, using the mode of the organic integration of the three of a pure mathematics model, a dynamic expert knowledge base and data mining to build an intelligent advanced diagnosis model; secondly, displaying the internal structure of the boiler by the means of three-dimensional visualization; finally, conducting correlation adjustment and analysis on the damage condition of the main heating surface of the boiler after prediction, conducting intervening adjustment on the main heating surface of the boiler after the advanced diagnosis, and forming closed loop management so as to avoid the occurrence of boiler failures. The system includes a mathematical model building module, a dynamic expert knowledge base building module, a data information mining module and an advanced fault diagnosis and early-warning module. The method and system can predict the future damage conditions of the four pipes of the boiler, and therefore taking measures in advance is convenient so as to reduce or avoid the occurrence of pipe explosion accidents.

Description

technical field [0001] The invention relates to a method and system for advanced diagnosis and analysis of a main heating surface of a boiler, belonging to the technical field of power plant boiler fault diagnosis. Background technique [0002] The main heating surfaces of boilers include steam drum, superheater tubes, reheater tubes, economizer tubes and water-cooled wall tubes. In addition to bearing high temperature and high pressure, they are also subject to corrosion and wear from the working fluid side or flue gas side. And fatigue damage, etc., the working conditions are relatively harsh. [0003] Statistics show that about 40% of accident shutdowns of thermal power generating units are caused by boiler failures, and 70% of them are caused by damage to the heating surface. In order to avoid unplanned outages caused by boiler failures, power plants can only seek a balance between daily operation and regular maintenance in a conservative manner. [0004] At present, s...
