Embodiment Construction

[0055] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments.

[0056] refer to Figure 1-5 , a water-cooling wall leakage monitoring method based on the inverse Abel transform algorithm, the steps are as follows:

[0057] S1. Obtain real-time flame information, including:

[0058] A CCD camera is set outside the fire viewing hole or other parts facing the flame. When the water wall leaks, the working medium will be ejected from the crack, which will affect the combustion of the furnace flame. At this time, the camera is used to take real-time pictures of the flame.

[0059] Among them, corresponding security measures should also be set for the CCD camera, including cooling facilities and servo drive fac...

Abstract

The invention discloses a water-cooled wall leakage monitoring system and method based on an inverse Abel transform algorithm, relates to the field of equipment monitoring, and relates to a water-cooled wall leakage monitoring method and a water-cooled wall leakage monitoring system. The method comprises the following steps: acquiring a flame image, transmitting the acquired image to a server through a communication cable for flame analysis and processing, then obtaining the development condition of water-cooled wall leakage according to a flame analysis result, and finally collecting and storing the acquired data. According to the method, the leakage degree is reversely analyzed through the influence of leakage on flames, and the accuracy and uniformity of cold wall leakage analysis are guaranteed; two indexes are adopted to measure the leakage degree of the water cooling wall, predictive analysis of leakage in different stages can be carried out, and criteria are provided for operators; in addition, manual fire observation operation after traditional leakage is avoided, and the risk operation during manual fire observation is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of equipment monitoring, in particular to a water-cooling wall leakage monitoring system and method based on an inverse Abel transform algorithm. Background technique [0002] Water wall leakage is one of the common problems encountered in boiler operation at present. The tube burst problem that affects the operation of the unit is often developed from the small leakage of the water wall, so it is necessary to monitor the leakage of the water wall. The monitoring of water wall leakage is currently carried out by three methods: feed water flow change, furnace temperature measurement and on-site inspection. When there is a small leakage point in the boiler water wall, the first two methods cannot be effectively identified, and only through on-site listening However, this method has high requirements on personnel and has certain risks, so it cannot be used as a universal monitoring method. After the water-cool...
