Coal-fired boiler heating surface depth fault early warning system based on industrial internet

Abstract

The invention discloses a coal-fired boiler heating surface depth fault early warning system based on the industrial internet, and relates to the technical field of the industrial internet, and the system comprises data collection, data conversion and transmission, big data fusion storage, data management, data object, data calculation, intelligent analysis and intelligent application. An incidence relation data model of the furnace tube temperature and the boiler working condition and a data model of the temperature and the position between the furnace tubes are established through an intelligent algorithm, real-time analysis and historical change analysis of the temperature of the furnace tubes are achieved, problem reasons are given out, early warning is conducted in advance, the operation mode can be adjusted in time in the operation process, and the fault development trend is improved or delayed. Through comparative analysis of wall temperature data of adjacent tube panels and change analysis of historical wall temperature data, preventive defect elimination can be carried out aiming at potential risks in unit dispatching, stopping and overhauling, the leakage risk of four tubes of a boiler is greatly reduced, and the safe and continuous operation capacity of a unit is improved.

Description

technical field [0001] The invention relates to the technical field of industrial Internet, in particular to an industrial Internet-based early warning system for deep faults on heating surfaces of coal-fired boilers. Background technique [0002] The Industrial Internet is a new type of infrastructure, application model and industrial ecology that is deeply integrated with the new generation of information and communication technology and the industrial economy. Through the comprehensive connection of people, machines, things, systems, etc., a new network covering the entire industry chain and the entire value chain is built. The manufacturing and service system provides a way to achieve digital, networked, and intelligent development of industry and even industries, and is an important cornerstone of the fourth industrial revolution. The Industrial Internet is not a simple application of the Internet in industry, but has richer connotations and extensions. It is based on ...

AI Technical Summary

Problems solved by technology

[0003] In thermal power plants, the furnace tube has been in the harsh working environment of high temperature and high pressure for a long time, and the deterioration of the furnace tube is very serious; the deterioration of the furnace tube greatly shortens the service life of the furnace tube, and makes the furnace tube potentially burst The risk of leakage is one of the main threats to the safe operation of thermal power boilers. Therefore, we propose an early warning system for deep faults on the heating surface of coal-fired boilers based on the industrial Internet to solve the above problems.
