Water in steam tubes can lead to trouble. However, a new solution, utilizing ultrasonic flowmeter technology, allows precise water detection in heat recovery steam generator (HRSG) systems, giving operators the opportunity to alleviate the problem before failure results.
Many combined cycle and cogeneration plants with heat recovery steam generators (HRSGs) were originally intended as baseload power sources or steam producers. In recent years, however, some have been repurposed as backup power sources for wind and solar farms as well as for conventional and peaking power plants.
HRSG-equipped systems are designed to capture energy that would otherwise be wasted by a combustion gas turbine.
