Environmental pressure is ramping up. Countries have issued targets to reduce or even eliminate the use of traditional fossil fuels in order to reduce emission of greenhouse gases such as…
heat recovery steam generator
The experience of South Humber Bank Power Station in the UK is just one example of overcoming corrosion challenges at power generation facilities. Facing issues during routine maintenance shutdown of…
Iberdrola SA and Mitsubishi Hitachi Power Systems (MHPS) recently commissioned the El Carmen combined cycle plant, located in Nuevo León, northeast Mexico. Wood supplied the two horizontal heat recovery steam…
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…
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…
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…
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…
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…
When U.S. President Jimmy Carter signed into law the Public Utility Regulatory Policies Act of 1978 (PURPA), he unintentionally ignited the worldwide deregulation of electricity markets, which in turn began…
It is fairly common for power plant engineers and maintenance managers to focus on fireside issues rather than waterside issues during routine maintenance outages. However, that could be a mistake.…
