Abstract

Most gas turbine plants and combined cycle cogeneration applications use either water injection or steam injection into the combustion zone to reduce the emission of nitrogen oxides (NOx) in the exhaust. For simple-cycle installations, water injection control is the most widely used means for controlling NOx emission. For combined cycle cogeneration, where waste heat from the exhaust of the gas turbine is used to produce steam either for process or combined-cycle electrical power generation, either steam injection or water injection is used to control NOx. Some gas turbines can accept massive quantities of steam injection (relative to that required for NOx, control) for both power augmentation and heat rate improvement.
