Analysis of thermal stress of slag layer for emergency shutdown in water wall gasifier;

Calculational method and influence analysis on temperature of water wall in natural circulation boiler;

Reason analysis on the abnormal metal temperature on water wall tube of ultra supercritical boiler;

Before installation,it has been discovered that the boiler water-wall pipes with small diameter and large wall-thickness of ultra-supercritical units in second-phase project for Huaneng Yuhuan Power Plant have comparatively serious unfused weld-joint defects,needing to carry out a large amount of inspection.

Welding water-walls of boiler through SAW method,how to improve the speed of welding is a technical point on the basis of ensuring the quality of welding joints.

The corrosion fatigue is a kind of failure commonly occurred on the water side of water-wall tubes in boiler,having strong covertness and large damaging force,threatening seriously safe production in power plants.

The waterwall corrosion of 410t/h boiler and how to deal with it;

Analysis on waterwall tube bursting of Unit 3 boiler in Shajiao C Power Plant;

Analysis and improvement of fireside corrosion of No.1boiler s waterwall tubes at burners site in Leiyang Power Plant;

An analysis and investigation on the leakage in water-wall tube of profiled flue of the coal-burning boiler;

Taking an accident of blast out of a boiler water-wall tube as on example,the article discussed the cause of the external uniform corrosion of the fire-side of pressurized water-wall tubes of a boiler and its preventive measures.

Wall thickness is a key index for water-wall tube inspection in power plant,in order to inspect the tube quickly and evaluate the wall thickness quantitatively,a new method combining the magnetic main flux(MMF) with ultrasonic technique was proposed.
