Abstract

Underground coal gasification (UCG) is a promising method to utilize deep coal resources that cannot be extracted with conventional techniques and to produce relatively cleaner energy from coal. There have been several laboratory and pilot-scale experiments conducted on UCG within hundred years. Some field-scale trials were conducted for experimental purposes, on the other hand, some others were applied for commercial interests. During these trials, the energy industry has built up experience, developed field demonstration strategies and put forward screening criteria for applicable field selection. In this study, UCG field demonstration strategies, and screening criteria are investigated. Some problems that are encountered with UCG are analyzed, and the engineering precautions are underlined. General information regarding all field trials is summarized, and some important trials are given in detail.

Özet

Yeraltı kömür gazlaştırma (YKG) tekniği, geleneksel yöntemler ile üretilmeye uygun olmayan kömür damarlarının değerlendirilmesi ve kömürden daha temiz yollarla enerji elde edilmesi amaçlarıyla uygulanmaktadır. YKG tekniği, yüz yılı aşkın bir süredir gerek laboratuvar gerekse gerçek saha ölçeklerinde denenmiş ve literatüre çeşitli çalışmalar kazandırılmıştır. Bazı kömür sahalarında pilot uygulamalar, bazılarında ise ticari ölçekte YKG operasyonları yürütülmüştür. Bu operasyonlar sırasında elde edilen deneyimler, tekniğin uygulanabilirliği açısından bazı yöntemlerin geliştirilmesini ve saha seçim kriterlerinin ortaya konulabilmesini sağlamıştır. Bu çalışmada bu yöntemler ve kriterler incelenmiştir. YKG sırasında karşılaşılan bazı önemli sorunlar ve bu sorunlara karşı alınabilecek mühendislik önlemleri aktarılmıştır. Bu zamana kadar gerçekleştirilen saha çalışmalarına dair genel bilgiler paylaşılmış ve önemli görülen denemelere dair ayrıntılı bilgiler verilmiştir.
