HRSG

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 […]

The operating profiles of traditional generators has changed to manage the variability of renewable resources. Several critical processes were not engineered to manage these highly variable operating profiles

Experience gained by a project team during a steam blowing operation for a combined cycle power project in Indonesia is described in this article. A specific challenge faced by the commissioning team is

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 […]

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
