Problems solved by technology

[0005] However, due to the operating noise in the furnace and flue, as well as the influence of the soot blowing process of the boiler soot blower, the leakage process of the boiler heating surface is a very complicated physical process under strong background noise. It is difficult to guarantee an early an...

Abstract

The invention relates to the monitoring and the diagnosis of operation states of a boiler, in particular to a system and a method for diagnosing leakage of a pressure-bearing pipe of a boiler. The system for diagnosing the leakage comprises a monitoring device, a storing device and a judging device; the monitoring device comprises a plurality of sensors which are arranged at each monitoring pointof a boiler unit and used for sensing and recoding operation parameters of the boiler unit in real time; the storing device is used for storing the operating parameters of the boiler unit in the normal working state; the judging device is communicated with the monitoring device and the storing device and can receive the real-time parameters from the monitoring device and judge whether leakage occurs to the pressure-bearing pipe of the boiler by comparing the real-time parameters with the parameters of the monitoring device. The invention is characterized in that when the real-time parameter from the monitoring device is higher than or is lower than that of the storing device in the normal working state and reaches a preset threshold value, the judging device judges that leakage occurs to the pressure-bearing pipe.

Description

technical field [0001] The invention relates to the monitoring and diagnosis of the operating state of the boiler, and more particularly relates to a leakage diagnosis system and method of the pressure-bearing tube of the boiler. Background technique [0002] At present, in the production and operation of large-scale thermal power generation units, the main problems affecting the availability of thermal power units are mainly reflected in the boiler equipment, and the main problem of the boiler is the leakage of the pressure tube-especially the unplanned outage caused by the leakage of the "four tubes". Transport, the leakage of four boiler tubes (ie economizer, water wall, superheater, reheater) accounts for about 30% of the total number of various accidents, and some units even have a proportion as high as 50%-70%. Boiler "four "Pipe" leakage has always been a major concern affecting the safe production and stable operation of thermal power plants. With the development of...
