Process | Heat Recovery Steam Generator
The HRSGs (Heat Recovery Steam Generator) are simple conversion natural-circulation in IP / LP section and Benson type steam generator for HP stage and generate steam in a high-, an intermediate- and a low-pressure section.
A condensate pre-heater is integrated in the HRSG. This arrangement enables higher efficiencies of the combined cycle power plant, by using the exhaust gas energy to preheat the condensate before it passes towards the feedwater pump and into the LP-System.
The HRSG is designed for outdoor installation and there is no bypass stack between the gas turbine and the HRSG. The HRSG is equipped with an exhaust duct at the end, which connects with the stack.
