THERMODYNAMICS ANALYSIS FOR WASTE HEAT RECOVERY SYSTEMS IN A CEMENT INDUSTRY

Öz

Recently, application of energy and exergy analyses to new projects presents most important data in terms of first design of systems and economic analyses. Evaluation and interpretation of analyses reports make determine the place, size and reasons of energy losses, therefore enhances the efficiency of systems. This project aims to thermodynamically inspect and develop the effects of Waste Heat Recovery (WHR) system on energy efficiency in cement factories. According to results, for all system, exergy losses value and totally exergy efficiency are founded 5038.61 kW and 55.69%, respectively. These results will constitute important data in terms of design and economical while building and operating waste heat recycling power plants. Thus energy saving and effective energy usage, which have great importance today, will be possible

ÇİMENTO SEKTÖRÜNDE ATIK ISI GERİ KAZANIM SİSTEMİNİN TERMODİNAMİK İNCELEMESİ

Öz

Son yıllarda enerji ve ekserji analizinin yeni projelerde uygulanması, sistemlerin ilk dizaynı ve ekonomik analizlerinin yapılması açısından önemli veriler sunmaktadır. Analiz sonuçlarının değerlendirilmesi ve getirilen yorumlarla enerji kayıplarının yeri, büyüklüğü ve nedenleri saptanabilmekte, dolayısıyla sistemlerin verimleri arttırılabilmektedir. Bu proje ile çimento fabrikalarında WHR sisteminin enerji verimliliği üzerine olan etkisi ve bu sistemin termodinamik olarak incelenmesi, geliştirilmesi amaçlanmaktadır. Elde edilen sonuçlara göre tüm sistem için ekserji kaybı 5038,61 kW ve ekserji verimliliği ise % 55.69 olarak bulunmuştur. Elde edilen sonuçlar atık ısı geri kazanım santrallerin kurulmasında ve işletilmesinde dizayn ve ekonomik açıdan önemli bir veri teşkil edecektir. Böylece günümüzde çok büyük önem teşkil eden enerji tasarrufu ve enerjinin en verimli şekilde kullanılması sağlanabilecektir
