Coal blending which provide increase in efficiency, decrease in repair-maintenance costs and emission of harmful gases in coal fueled power plants, is in the interest of many countries both scientifically and practically. Nevertheless, there are many power plant operators in different
countries showing no adequate interest to this important issue. This paper briefly explains the importance of blending, types and methods of blending, total coal quality management and importance of stockyard equipment selection especially for mine-mouth power plants and points out that all these are essential parameters of a good blending.

Anahtar Kelimeler

TERMİK SANTRALLAR İÇİN KÖMÜR HARMANLAMA

Öz

Kömürle çalışan santrallarda verim artışı, tamir bakım masraflarında ve zararlı gazların misyonunda azalmayı sağlayan kömür harmanlama konusu bilimsel ve uygulamalı olarak birçok lkede gerekli ilgiyi görmekle beraber, konuya yeterli ilgiyi göstermeyen farklı ülkelerde santral
işletmecileri de bulunmaktadır. u makale, özellikle yanındaki kömür ocağından yakıt sağlayan santrallar için bu konuya neden nem verilmesi gerektiğini, harmanlama yöntemlerini, toplam kömür kalite yönetimini, stok sahası kipman seçiminin önemini kısaca belirtmekte ve tüm bu hususların iyi bir harmanlama için erekli parametreler olduğuna işaret etmektedir.

Anahtar Kelimeler

Harmanlama, Yığma, Yığından alma, Stok sahası ekipmanı, Kalite yönetimi
