Description

Technical Field

[0001] The invention belongs to the field of wall-type tangential circle boiler control, and in particular relates to a high-temperature corrosion detection control device and method for a wall-type tangential circle boiler based on real-time CO measurement. Background Art

[0002] The high-temperature corrosion of the furnace water-cooled wall was first discovered in the liquid slag furnace with a working medium temperature of about 317°C in the water-cooled wall tubes of the high-pressure boiler. Later, more serious water-cooled wall tube corrosion problems were found in high-parameter, large-capacity power station boilers, especially those burning lean coal. The corrosion rate of the boiler with severe corrosion is as high as 3.0mm / year. The possibility of accidents such as boiler water-cooled wall tube bursts caused by this has increased significantly, which will seriously affect the safe production of electricity. Many of the ultra-supercritical unit boilers put into production recently use wall-type cut-circle boilers. With the continuous increase in operating time, most of this type of boilers have experienced high-temperature corrosion of the water-cooled wall. The ultra-supercritical boilers of the 660MW units of a power plant of Huadian Anhui Branch and the ultra-supercritical boilers of the 660MW units of a power plant of Datang Jiangsu Branch have experienced large-scale high-temperature corrosion of the water-cooled wall. In severe cases, the high-temperature corrosion phenomenon spreads throughout the entire burner area, seriously endangering the safe operation of the unit. The power plant has to carry out large-scale plasma anti-corrosion spraying on the high-temperature corrosion area during the overhaul, which is very expensive.

[0003] Although the high temperature corrosion of wall-type tangentially fired boilers can be controlled by analyzing the composition of flue gas and controlling the pressure and flow of the burner according to the analyzed situation, in this process, the analysis results may be inaccurate when analyzing the flue gas.

This method further enhances the accuracy of measurement.

The piston, box body, cylinder, etc. of the present invention adopt a modular design, which is convenient for later maintenance and replacement of parts, reduces equipment downtime, and improves operation efficiency.

[0016] The method of the present invention calculates the CO concentration by a dual mode of absorbance measurement and chemiluminescence reaction, which complement each other, effectively reduce the error that may be caused by a single detection method, and ensure more accurate results.

The number of photons emitted by the excited state intermediate of the present invention when returning to the ground state is highly correlated with the CO concentration. The detection of the number of photons provides a sensitive response to trace CO, further enhancing the measurement sensitivity.

The working method of the high temperature corrosion detection and control device of the wall-type tangential boiler based on real-time measurement of CO is characterized in that: The following steps are involved: Extracting air from the hollow tube (10) through a vacuum system until the hollow tube (10) is in a vacuum state; The flue gas at the water-cooled wall surface of the boiler is placed in the hollow tube (10) through the exhaust system; A light source (41) emits light, the light passes through a monochromator (42) and is decomposed into wavelengths matching the characteristics of CO, the emitted light passes through the flue gas and the absorbance is detected by a detector (44), and the concentration of CO is calculated according to the measured absorbance using the Lambert-Beer law through a data analysis module (45); The cylinder (62) and the piston (63) cooperate to spray the chemiluminescent reagent in the hollow tube (10) in a mist form to react with the flue gas to generate an excited intermediate. When the excited intermediate returns to a stable ground state, photons are emitted through the photon emitter (51). At this time, the photons pass through the flue gas and the number of emitted photons is detected by the photon detector (53), thereby determining the concentration of CO. The average value of the CO concentration is obtained, and the pressure and flow rate of the burner are controlled accordingly according to the average value of the CO concentration.
