Temiz kömür teknolojileri, kömürün üretimi, hazırlanması ve kullanımında çevresel kabul edilebilirliği ve verimliliği artıran uygulamalar olarak tanımlanmaktadır. Temiz kömür teknolojileri ile emisyon ve atıkları azaltarak birim ton başına elde edilecek enerji miktarını artırmak mümkündür. Bununla birlikte, günümüzde çevrenin korunması ve iklim değişikliğiyle mücadeleye ilişkin yasal düzenlemelerin bir sonucu olarak uyulması zorunlu katı yaptırımlar mevcuttur. Bu noktada özellikle oksi-yakıt yanma işleminin (CO2 depolama imkânı ile) yer aldığı "temiz kömür yakma teknolojileri" ön plana çıkmaktadır. Bu çalışmada, brüt elektrik üretimi 500 MW olan bir termik santralde oksijen ile yakıt yakma yöntemi ele alınmıştır. Bu termik santral modelinde ayrıca bir akışkan yataklı kurutucu, bir desülfürizasyon tesisi ve bir CO2 depolama prosesi bulunmaktadır. Farklı özellikteki kömürlerin yanma sonuçları incelenmiş ve işletme parametrelerine olan etkileri araştırılmıştır.

Clean coal technologies are defined as applications that improve environmental acceptability and efficiency in producing, preparing and using coal. With clean coal technologies, it is possible to increase the amount of energy obtained per unit ton by reducing emissions and wastes. However, today there are strict sanctions that must be followed due to the legal regulations on the protection of the environment and combating climate change. At this point, the clean coal-burning technologies in which the oxy-fuel combustion process (with the possibility of CO2 storage) takes place come to the fore. In this study, the method of burning fuel with oxygen in a thermal power plant with a gross electricity generation of 500 MW was discussed. This thermal power plant model also has a fluidized bed dryer, a desulphurization plant, and a CO2 storage process. The combustion results of different properties of coals were examined, and their effect on operating parameters was investigated..
