Economic Analysis of Cogeneration System for Atatürk University Campus

Abstract

The increasing energy needs around the world and the depletion of fossil fuels used to meet this need, pollution to the environment, global warming have increased humanity's interest in alternative energy sources. In this context, cogeneration systems have gained value recently and found applications. In this study, natural gas and electricity consumption values of Ataturk University were examined and graphs of these values were created. Economic analysis of the cogeneration system intended to be established for Ataturk University Campus was carried out. Ataturk University campus's annual electricity needs were 31.352.552 kW. Equivalent energy consumption was calculated as 117.621.184 kW, equivalent to annual gas expenditures of 12.282.914 m3. 28.800.000 kW of electricity can be generated annually with the cogeneration system considered for the campus. However, according to the results obtained, only a fraction (18.6%) of the thermal energy needed by ataturk university campus will be covered by this system.

Atatürk Üniversitesi Yerleşkesi İçin Kojenerasyon Sisteminin Ekonomik Analizi

Öz

Dünya genelinde artan enerji ihtiyacı ve bu ihtiyacın karşılanması için kullanılan fosil yakıtların tükenme durumu, çevreye verdiği kirlilik, küresel ısınma gibi durumlar insanlığın alternatif enerji kaynaklarına olan ilgisini arttırmıştır. Bu bağlamda kojenerasyon sistemleri son dönemde değer kazanmış ve uygulama alanları bulmuştur. Bu çalışmada Atatürk Üniversitesi’ne ait doğalgaz ve elektrik tüketim değerleri incelenmiştir ve bu değerlere ait grafikler oluşturulmuştur. Atatürk Üniversitesi Yerleşkesi için kurulması düşünülen kojenerasyon sisteminin ekonomik analizi yapılmıştır. Atatürk Üniversitesi kampüsünün yıllık elektrik enerjisi ihtiyacının 31.352.552 kW olduğu görülmüştür. Yıllık 12.282.914 m3 doğalgaz harcamasına denk gelen eş değer enerji tüketimi 117.621.184 kW olarak hesaplanmıştır. Kampüs için düşünülen kojenerasyon sistemiyle yıllık 28.800.000 kW elektrik üretilebilecektir. Ancak elde edilen sonuçlara göre Atatürk Üniversitesi kampüsünün ihtiyaç duyduğu ısıl enerjinin yalnızca bir kısmı (%18.6) bu sistem tarafından karşılanabilecektir.
