Boiler operation safe state five-dimensional radar graph monitoring method

Abstract

The invention provides a boiler operation safe state five-dimensional radar graph monitoring method. A five-dimensional radar graph is formed by concentrically arranging three circles with different radii to form three areas in different safe states, and the three areas include the first-stage danger operation state area, the second-stage monitoring operation state area and the third-stage safe operation state area from inside to outside. Five outward divergent lines are led out from the circle center of the concentric circles to serve as polar coordinate lines for displaying real-time monitoring parameters such as the water-cooling wall temperature, the superheater temperature, the boiler system pressure, the boiler tube wall thickness and the boiler tube remanent life dimensions of a boiler during operation; the extreme values of the water-cooling wall temperature, the superheater temperature, the boiler system pressure, the boiler tube wall thickness and the boiler tube remanent life data are found out correspondingly and displayed the polar coordinate lines of the respective dimensions; the point locations are connected through straight lines to achieve the purpose of displaying the safe state of the boiler. Through the boiler operation safe state five-dimensional radar graph monitoring method, the safety problems of an online monitoring system and offline detection data can be reflected directly, and the boiler monitoring efficiency is improved.

Description

technical field [0001] The invention relates to a method for monitoring the safety state of boiler operation. In particular, it relates to a five-dimensional radar graphic monitoring method for boiler operation safety state. Background technique [0002] At present, there are many online and offline monitoring systems for boilers, but they generally monitor one temperature or pressure, and only one parameter is monitored. Trends are not clear. A single data often cannot represent the situation of the entire furnace, which may cause misjudgment to managers. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a five-dimensional radar graphic monitoring method for the safety status of boiler operation that can display the real-time safety level of all boiler operations for boiler managers, and intuitively reflect the safety issues of the online monitoring system and offline detection data. [0004] The technical solu...
