Moisture SeparatorReheaterThe function of the Moisture Separator Reheater(MSR) is to improvethe quality of the high-pressure turbine exhaust steam before itenters the low pressure turbine. The operation mechanicallyremoves the moisture from the high-pressure turbine exhauststeam, then reheats the dry steam almost to its initial live steamtemperature by passing it though a hot tube bundle. Depending onexisting turbine conditions, we can replace the internal tube bundleon site or replace the tube bundle and shell on site
