Investigation of the potential for heat recovery at low, medium, and high stages in the Turkish industrial sector (TIS): An application

In this study, the potential for waste heat recovery is examined based on real data from 1990 to 2011 (a 21-year period) for processes at low-, medium- and high-temperature levels. The first part of this study included a theoretical analysis for determining the potential for heat recovery at these temperature stages. Second part stated an application in the industrial sector. This study is conducted using actual data for this sector from 1990 to 2011. The total available energy recovery from waste heat recovery appliances for products, flue gas and wall heat recovery was calculated to be 224-503 PJ over the years studied. The available waste heat potential from the total energy in this sector is determined to be 36 to 40% for these years. The technical potential is estimated to be 55 to 65% of these values. The total technical-potential waste energy recovery in the low, medium, and high temperature stages using waste heat recovery appliances for products, flue gas and wall heat recovery was estimated to be from 224 PJ to 503 PJ over the years studied. Usage of technology device according to efficiencies for the sector was estimated to be 22.40 PJ/year to 67.45 PJ/year.
