Abstract

The invention discloses an abrasion-proof and explosion-proof grid deployment and control detection method which comprises the following steps: firstly, determining a transverse line and a longitudinal line, determining a collection sampling point, then carrying out first-time measurement on the collection sampling point to collect data, carrying out second-time measurement on the collection data after a unit runs for ten thousand hours, finally, calculating the corrosion rate through a background management system according to the first measurement data, the second measurement data and the operation time t, and evaluating whether the water wall tube is replaced or not according to the corrosion rate. According to the invention, the inspection area is fully covered, and the key area is not missed; the inspection work is processized, and the work efficiency is stably improved; data recording is more standard, and a problem area is more visual; and analysis data are compared, and the corrosion rate is dynamically mastered.

Description

technical field [0001] The invention relates to a wear-proof and explosion-proof grid layout control detection method, which belongs to the technical field of non-destructive detection. Background technique [0002] In recent years, with the rapid development of my country's modern industry, it has brought great impact and pressure to the coal-fired market, and more low-quality coal-fired raw materials have been produced on the market, which makes the management of boilers in thermal power plants more difficult. , The heating surface of the boiler frequently leaks safety accidents. Moreover, it presents a development trend of diversification, complication and complexization of accidents. With the increase of high-parameter and large-capacity thermal power units in my country in recent years, if an outage event occurs outside the planned scope, it will seriously affect the improvement of the economic benefits of thermal power plants, which will not only cause huge economic lo...
