Abstract

In this study the energy and exergy analysis have been applied to the power plant in the Iron and SteelWorks Co. This plant consist of two parts, which could be described as old and new sections. These components worktogether as an integrated power plant. In this work, the irreversibility rates and energy losses of each units have beendetermined separately by energy and exergy analysis. Also, units have been compared by irreversibility rates andsome considerable suggestions have been made to improve efficiency. It is suggested to remove three pressurereduction units (PDD1, PDD2, PDD3), have a total irreversibility rate of 6054 kW, from the existing plant andreplaced by a turbo-generator (TG4). Calculated results showed that the increments of overall thermal ( or first law)efficiency and overall exergy (or second law) efficiency of suggested plant were 2.27 and 2.21 %, respectively.

Özet

Bu çalışmada, Demir-Çelik Fabrikasındaki güç santraline enerji ve ekserji analizi uygulanmıştır. Santral, eskive yeni olmak üzere iki kısımdan oluşmaktadır. Bu kısımlar birbirleriyle entegre olarak çalışmaktadır. Bu çalışmada,her bir ünitenin enerji kayıpları ve tersinmezlikleri enerji ve ekserji analizi uygulanarak belirlenmiştir. Ayrıca,üniteler tersinmezliklerine göre karşılaştırılmış ve verim artırıcı bazı önemli öneriler yapılmıştır. Mevcut santraldekitoplam tersinmezliği 6054 kW olan üç basınç düşürücünün (PDD1, PDD2, PDD3) kaldırılması ve yerine bir turbo- jeneratör (TG4) konulması önerilmiştir. Yapılan hesaplamalar sonucunda, önerilen bu santralin mevcut santrale göregenel (1. Kanun) verim ve genel ekserji verim artışları sırasıyla % 2.27 ve 2.21 olarak belirlenmiştir
