Paper Title
Exergy And Economic Analysis Of Dual Pressure Waste Heat Recovery Boiler

Abstract
Waste heat recovery systems (WHRS), uses exhaust gas in the boiler, are very important in terms of increasing energy efficiency and reducing green gas emissions. Due to this reason, WHRS get more importance. Although dual pressure WHR boiler is more efficient than single pressure boiler, dual pressure boiler needs more heat transfer surface are. When the stage of boiler increases, the size of boiler also increases so it makes dual pressure more expensive. Engine load, exhaust gas temperature and fuel types, effect exhaust gas energy level, are the efficiency parameters for WHRS. In this study two-stroke Diesel engine performance is analyzed in terms of thermal efficiency, engine load, specific fuel oil consumption (SFOC), exergy efficiency and exegetic performance coefficient (EPC). It is shown that which boiler type is suitable due to the working condition in term of technical size and economic parameters. Keywords- Waste Heat Recovery System (WHRS); Single Pressure Boiler; Dual Pressure Boiler; Two-Stroke Diesel Engine; Energetic Efficiency; Exegetic Performance Coefficient.
