Abstract

In this study, the spontaneous combustion characteristics of coal samples obtained from Çan Lignite Corporation’s (ÇLC) open pit and stockpiles were determined by the crossing point temperature method. Accordingly, it was determined in the experiments that the average heating rates (AHR) of coals ranged from 0.92 to 3.93 °C min–1 ; ignition or crossing point temperatures (CPT) from 150 to 182 °C and susceptibility index (IFCC) from 5.04 to 33.33 min-1 . As a result, the liability of 21 coal samples to spontaneous combustion tendency was determined to be in the “medium-high” risk category

Özet

Yapılan bu çalışmada, Türkiye Kömür İşletmeleri (TKİ) bünyesinde faaliyet gösteren Çan Linyitleri İşletme Müdürlüğü (ÇLİ) açık ocak ve stoklarından temin edilen kömür numunelerinin kendiliğinden yanma karakteristikleri kesişim noktası metodu ile belirlenmiştir. Buna göre elde edilen sonuçlarda, kömürlerin ortalama sıcaklık artışlarının (OSA) 0,92-3,93 °C dk-1 ; tutuşma ya da kesişim noktası sıcaklıklarının (KNS) 150-182 °C; yatkınlık indeksi (IFCC) değerlerinin ise 5,04-33,33 dk-1 arasında değiştiği yapılan deneylerde tespit edilmiştir. Sonuç olarak; 21 adet kömür örneğinin kendiliğinden yanmaya yatkınlıklarının “orta-yüksek” risk kategorisinde yer aldığı belirlenmiştir.
