Abstract
In the course of 10 year operation of six TP 100A steam generators 72 emergency operation interruptions occurred due to the piercing of screen pipes in the combustion chamber. According to investigations carried out by the NPO, CKT, VTI, KPI and Soyuzenergo institutes, the damage occurred mainly because of the destructive influence of external gas corrosion processes, overheating and fatigue of metallic pipes, as well as unstable heat and temperature regime in the combustion chamber. Large-scale measurements of the main thermodynamic parameters of the combustion chamber of the TP-100A steam generator were carried out in order to increase service life of screen pipes. It was found that the temperature of screen pipes increases 2.5 C/month because of deposition of sediments. Regular cleaning of screen pipes in intervals of 18 months is recommended as a very efficient means of prolonging their service life. 1 ref.
