Exergetic and thermoeconomic analyses of diesel engine powered cogeneration: Part 2 – Application

Abstract: a b s t r a c tThis paper is Part 2 of the study on the exergetic and thermoeconomic analysis of diesel engine powered cogeneration (DEPC) systems. In Part 1, formulations and procedure for such a comprehensive analysis are provided while this paper provides an application of the developed formulation that considers an actual DEPC plant installed in Gaziantep, Turkey. The plant has a total installed electricity and steam generation capacities of 25.3 MW and 8.1 tons/h at 170°C, respectively. Exergy destruction… Show more

“…Cogeneration systems utilize the waste heat produced during electricity generation and apply it for heating purposes. Since cogeneration, or combined heat and power (CHP), systems produce both thermal energy (generally in the form of steam or hot water) and electricity, the first law efficiency can be increased from around 35% to 55% in conventional power plants to over 90% in CHP systems [1][2][3]. Reciprocating CHP units are generally applicable in low and medium power cogeneration units.…”

“…The sizes of reciprocating CHP units depend on fuel type and use. These can range from 50 kW to 10 MW for natural gas, from 50 kW to 50 MW for diesel, and from 2.5 MW to 50 MW for heavy fuel oil [1][2][3]. In compression ignition (IC) engines, four methods to utilize waste heat exist: exhaust gas, engine jacket cooling water, lube oil cooling water, and turbocharger cooling water.…”

“…Abuşoğlu and Kanoğlu [2] performed an energy, exergy, and exergoeconomic analyses for a diesel engine powered cogeneration (DEPC) plant using actual operating data. Specific exergy costing (SPECO) method was used to achieve thermoeconomic analysis of the power plant [2,3]. Abuşoğlu and Kanoğlu [4] carried out a review study which includes a brief historical overview on the exergoeconomic analysis and optimization for combined heat and power production (CHPP).…”

“…In the second part of the study, the diesel-powered cogeneration system, founded in Gaziantep, Turkey, was evaluated using the formulations developed in the first part of the study. 8 The exergy efficiency of the facility was calculated as 40.6%, while the specific unit exergetic cost of the power produced by the plant was 10.3 US$/GJ.…”
