Abstract

In branches of industry too much energy consuming such as cement sector, controlled use of energy, only it is possible to know how energy is distributed in the system. In cement production process, a large portion of the heat losses which is due to energy consumption consist of convection and radiation heat losses from the surface of rotary kiln. In this study, empirical equation was derived for heat loss from surface of rotary kiln in a cement factory using empirical equations and statistical modeling techniques by the help of temperatures measured surface of rotary kiln. Measured with thermal cameras and the data necessary for experimental modeling was obtained the factory central control room. Total heat loss of system was calculated using Matlab. Statistical analysis related to results was carried out by Minitab 15.1.1 program. It was concluded that heat losses throughout rotary kiln increased toward the center of the kiln.

Özet

Çimento sektörü gibi üretimde çok fazla enerji tüketen sanayi dallarında, enerjinin kontrollü kullanımı, ancak enerjinin sistemde nasıl dağıldığının bilinmesi ile mümkün olur. Çimento üretim prosesinde enerji tüketiminin nedeni olan ısı kayıplarının büyük bölümünü, döner fırın yüzeyinden konveksiyon ve radyasyon ile olan ısı kayıpları oluşturmaktadır. Bu çalışmada, döner fırın yüzeyinden ölçülen sıcaklıklar yardımıyla fırın boyunca ısı kaybı için ampirik denklem ve istatistiki modelleme teknikleri kullanarak ampirik denklem türetilmiştir. Termal ölçüm kameraları ile ölçülen ve deneysel modelleme için gerekli olan veriler, fabrika merkezi kontrol odasından alınmıştır. Sistemin toplam ısı kaybı Matlab programı kullanarak hesaplanmıştır. Sonuçlar ile ilgili istatistiksel analizler Minitab 15.1.1 programı ile gerçekleştirilmiştir. Fırın boyunca ısı kayıplarının özellikle fırın merkezine doğru arttığı sonucuna ulaşılmıştır.
