APPLICATION AND DESIGN OF AN ECONOMIZER FOR WASTE HEAT RECOVERY IN A COGENERATION PLANT
ABSTRACT
Energy increase cost has required its more effective use. However, many industrial heating processes generate waste energy. Use of waste-heat recovery systems decreases energy consumption. This paper presents case study of waste heat recovering of the exhaust flue gas in a 1415 kWe cogeneration plant. This waste heat can be recovered by installing an economizer to heat the condensed and fresh water in thermal degasification unit and reduce steam use for maintaining the temperature of 105˚C for oxygen removal. Design methodology of economizer is presented.
