Merkezi Bir Isıtma Sisteminde Enerji ve Ekserji Analizinin Eksergoekonomik Yönden Değerlendirilmesi

Öz

Bu çalışmada Van Yüzüncü Yıl Üniversitesi kampüsünde toplam 20 ton/saat buhar üreten merkezi ısıtma sisteminin ekonomik ve Eksergoekonomik analizi yapılmıştır. Yapılan analiz sonucunda sistemin en önemli bölgesi olan kazanlardaki toplam enerji verimi ortalama olarak %90, ekserji verimi ise %31 olarak bulunmuştur. Tüm sistemin ekserjetik verimi ise %29 olarak bulunmuştur. Eksergoekonomik analiz sonucunda sistemin yıllık yakıt tüketim bedeli, yıllık ürün maliyeti bedeli, sisteme giren ve çıkan parametrelerin birim ekserji maliyet bedelleri hesaplanmıştır. Hesaplar sonucunda ürünün saatlik maliyeti: 291,78 $/h, yakıtın saatlik maliyeti: 252,30 $/h, olarak bulunmuştur.

Exergoeconomic Evaluation of Energy and Exergy Analysis in a Central Heating System

Öz

In this study, the economical and exergoeconomik analysis of the central heating system which produces a total of 20 tons/hour of steam was conducted in in the Van Yüzüncü Yıl University campus. As a result of the analysis, the total energy efficiency of the boilers, which is the most important part of the system, was found to be 90% and the exergy efficiency as 31%. The exergetic efficiency of the whole system was found to be 29%. As a result of the exergoeconomic analysis, the annual fuel consumption cost of the system, the annual product cost price, the unit exergy cost of the parameters entering and leaving the system were calculated. As a result of the calculations, the hourly cost of the product was found to be: 291.78 $/h, the hourly cost of fuel: 252.30 $/h.
