The improvement of energy efficiency of cogeneration system by replacing desuperheater with steam–air preheater

Energy Reports, 2020
Industrial processes require thermal energy in form of saturated steam. Cogeneration system in a process industry uses an industrial boiler to produce superheated steam, which is subsequently expanded in a condensing-extraction steam turbine.
