Thermo-economic Analysis of Gas Engine Combined Heating and Power System

İngilizce (OpenAlex)

Industrial combined heat-power systems are to obtain electric and steam from the same gas engine using a single type of fuel. In the combined heating and power systems, the cooling cycle is also used. In this study, low cost and high profitability heating and power system were established in an industrial process and economically evaluated. The energy expenses of the plant were calculated; the cogeneration system is designed and has been activated. The electricity, heating energy amounts obtained by the cogeneration system were determined. The economic analysis of the system's input values and the economic analysis of the output values were made comparatively and the first investment payback period has been calculated. Both systems have been found to be profitable for the process but the repayment period was different. The efficiency of the first system was 90.78% and the payback period was 3,007 years, the efficiency of the second system was 90.74% and the payback period was 2,671 years.
