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
JCE-once-through-boiler-HRSG

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…


New Monitoring and Analytics Tools Improve Plant Performance

Industrial Internet of Things (IIoT) technologies can help make electric generating plants more efficient while increasing availability. The electric power industry is going through a transformational change: increasing renewables from…


Operating HRSGs with Elevated Feedwater pH

Cycle-chemistry guidelines for combined cycle power plants have changed over the years, with pH frequently maintained between 9.6 and 10.0 today. That can cause problems with condensate polisher operation. Plant…


Next-Generation HRSGs Start Fast and Reduce Emissions
HRSG-DrumPlus

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…
