Combined Cycle Gas Turbine (CCGT) use exhaust gases from gas turbine (GT), which in basic systems are ejected to environment as discharge loss, for steam generation in Heat Recovery Steam Generator (HRSG). Higher unit efficiency achieved inter alia by using in boiler low and high pressure circuit allow to greater use of turbine exhaust gases enthalpy. Modular design solutions with tight structure, preferred on construction site, may be a problematic for maintenance services during operation and overhauls. This paper presents general operational problems of HRSG as well as detailed solutions for boiler OU-192. We discuss scope and results of diagnostic tests required to assess technical condition of the pressure elements, after 100 000 hours operation, with the support of the software LM System PRO+
