Research On Technical Retrofit Of FSSS For Large & Medium-sized Thermal Power Plant

FSSS (Furnace Safeguard Supervisory System), which is usedin e1der unit that has been brought into operation, of the 1argeand fnediumsized Therma1 Power P1ant. After understanding thesystem structure and characteristic of action, rea1izing thetheory of FSSS, quondam 1ogic of unit is ana1yzed a11--sided.Based on these, a set of method, which is about technica1retrofit, is found out. Meanwhi1e, improved method that is aboutexisting prob1ems in FSSS is taked out. The theory of FSSS andpract ice are combined via working in practice. A11 of these haveinstruct iona1 funct ion and app1 ied va1ue in work aftert ime.Li Song (Therma1 Power Engineering)Directed by Prof. Zhang ChunFa...
