Consensus on Operating Practices for Control of Water and Steam Chemistry in Combined Cycle and Cogeneration
Download citation file:
The Combined Cycle Task Group of the ASME Research and Technology Committee on Water and Steam in Thermal Systems has prepared the following set of chemical operating limits specifically to address the requirements for heat recovery steam generators.
A common configuration for power generation utilizes a natural gas-fired combustion turbine (CT) coupled with a heat recovery steam generator (HRSG) that extracts heat from the gas turbine exhaust to produce steam for a separate steam turbine/generator set. Often multiple CT/HRSG units feed a single steam turbine. Some combustion turbines can use fuel oil as either the primary or back up fuel....
