Abstract

In this study, the causes of variation in monthly production costs in a power plant have been investigated and a solution is proposed. It is determined that the most important cause is the variation of coal calorific values which is feeding to boiler. For this aim, Cp,and Cpk-coefficients have been calculated to determine the suitability of coal calorific values. An additional coal enrichment plant has been proposed to decrease the variation and a model is constiucted to indicate whether this investment is effective or not. Consequently, it is determined that this new investment has decreased both coal calorific variation and costs.

Özet

Bu çalışmada bir elektrik üretim santralinde aylık üretim maliyetlerinin artış nedenleri ve azaltılması için yapılabilecek çalışmalar incelenmiştir. Termik santralde kazana beslenen kömür kalori değerlerindeki değişkenliğin, maliyeti artıran en önemli faktör olduğu belirlenmiştir. Bu amaçla Cp ve Cpk. katsayıları ile maliyet artışları arasında bir ilişki kurulmaya çalışılmıştır. Değişkenliğin azaltılması amacıyla ek bir kömür zenginleştirme tesisi kurulması önerilmiş ve bu yatırımın ekonomik olarak anlamlı olup olmadığı, oluşturulan bir model ile incelenmiştir. Sonuç olarak bu ek yatırım hem kömür kalorisindeki değişkenliği hem de maliyetleri azaltmıştır.
