A method for reducing NOx and recovering waste heat from a stream of exhaust gas from a fossil fuel fired turbine includes contacting the stream of exhaust gas between an economizer and an evaporator with ozone gas to convert the NO to nitrogen dioxide (NO2) thereby forming a stream of exhaust gas comprising NO2 and residual NO. The method further includes, contacting the stream of exhaust gas comprising NO2 and residual NO with water mist to create an exhaust stream comprising nitric acid (HNO3) and residual NO. The method further includes cooling the stream of exhaust gas comprising HNO3 and residual NO, collecting a first residual water film on a first condensing medium to capture the HNO3 and removing the first water film and HNO3.
