The rising consumption of energy with growing population is an important problem not only in our country but also in the world. Since imported energy is used especially in the industry and buildings, researchers have to design more efficient systems, increase the efficiency of existing systems, and use particularly the alternative energy sources. One of the alternative energy sources is biomass. The pellet fuel is one of the biomass fuels. In this study, the literature is reviewed. The technologies, thermal performances and emissions of pellet-fuelled stoves and boilers are evaluated. The market conditions are determined. It was seen that the thermal efficiencies of systems were above %90, air pollutant emissions (except dust) were at low level.It has been observed that systems have development potential for new applications such as cogeneration systems.

Pelet Yakıtlı Yakma Sistemlerinin Isıl Performans ve Emisyon Açısından İncelenmesi

Öz

Artan nüfusla birlikte enerji tüketimindeki artış enerjiyi tüm dünyada olduğu gibi ülkemizde de önemli bir problem olarak karşımıza çıkarmaktadır. Özellikle sanayi ve konutlarda kullanılan enerjinin büyük çoğunluğunun ithal olması, araştırmacıları daha verimli sistemler tasarlamaya, mevcut sistemlerin verimini arttırmaya ve özellikle de alternatif enerji kaynaklarını kullanmaya zorlamaktadır. Alternatif enerji kaynaklarından biri biyokütledir. Pelet yakıtı da biyokütle kaynakları arasında yer almaktadır. Bu çalışmada güncel literatür incelenerek pelet yakıtlı soba ve kazanların teknolojileri, ısıl performansları ve emisyonları değerlendirilmiş, piyasa durumu belirlenmiştir. Sistemlerin ısıl verimlerinin %90 üzerinde gerçekleştiği, hava kirletici emisyonlarının toz hariç düşük seviyede olduğu görülmüştür. Kojenerasyon sistemleri gibi yeni uygulamalar için uygun ve gelişme potansiyeline sahip oldukları gözlemlenmiştir.
