heat recovery steam generator

Power plant construction and retrofit projects come in all shapes and sizes, but they all generally have at least one thing in common: complexity. There are usually a lot of moving pieces that must be managed. This can include sourcing the right materials and components, getting equipment delivered to the site at the right time, […]

The heyday of combined cycle plant construction (especially in the U.S.) was at the start of the millennia. Between 2000 and 2005, about 130 GW of natural gas–fired combined cycle plants opened in the U.S.

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 CO2. Gas turbine original equipment manufacturers (OEMs) are responding by investing in hydrogen (H2) combustion. They are spending heavily on the development of combustors and […]

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 heat recovery steam generators (HRSGs), South Humber began using VCI (Vapor Corrosion Inhibitor) technology to solve their dew point corrosion problem in 2009. Although it […]

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 generators (HRSGs) for the plant. The 875-MW combined cycle plant is based on two 300-MW MHPS M501J combustion turbines and is the first plant built […]

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 and steam turbine modifications can provide sizable economic gains. But these improvements often come at the cost of the serviceable (useful) life of the high-temperature […]

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 that the conventional heat recovery steam generator (HRSG) does not enable fast-acting power generation demanded by modern grid systems. John Cockerill Energy’s vertical once-through boilers […]

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 good news is HRSG suppliers are adapting to the market demands and are designing the next generation of HRSGs to have cycling-friendly—also called fast-start—features. One […]

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 always

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
