How do HRSG Boilers work? - AskingLot.com

13/5/2020 · The HRSG absorbs heat energy from the exhaust gas stream of the combustion turbine. The absorbed heat energy is converted to thermal energy as high temperature and pressure steam. The high-pressure steam is then used in a steam turbine generator set to produce rotational mechanical energy.

(6) TDS expressed as ppm (mg/l) in steam is proportional to TDS expressed as specific conductivity in the boiler water in each pressure range. For example, 5400 pS/cm in the boiler water is expected to produce 1 ppm (mg/l) TDS in the steam and 1100 pS/cm in the boiler water is expected to produce 0.2 ppm (mg/l) TDS in the steam for boilers operating at 0-300 psig.
