The Cost of Turbine Modifications on HRSG Tubing

Turbine modifications will shorten the life of heat recovery steam generator (HRSG) tubing, but the most dramatic reductions may not be where you expect. Combined cycle power plant gas turbine…

Flexible Small-Scale Generation Empowered by Once-Through Boiler Technology

Distributed generation integrated with intermittent renewable generation responds to the growing need for highly flexible small-scale (less than 100 MW) power generation resources. The limiting factor facing plant designers is…

Next-Generation HRSGs Start Fast and Reduce Emissions

Today’s heat recovery steam generators (HRSGs) are suffering reliability problems, mainly because they’re being operated in the cycling mode instead of the baseload mode for which they were designed. The…

Analytical Tool Helps HRSG Operators Compare Equipment Reliability

Ever since deregulation came to the power industry, combined cycle plant managers have been trying to benchmark their production metrics and cycling costs against those of their competitors. There has…

Managing Thermal Quench Damage at Power Plants

Attemperation equipment is necessary to control steam temperatures at many power plants. However, when the equipment functions improperly or the design is flawed, thermal quenching/shock can damage piping. Proper inspections…
