Abstract

   Sosyal ve ekonomik kalkınma, nüfus
ve yaşam standartlarındaki artışın sonucu olarak enerji tüketimi tüm dünyada
sürekli artmakta ve bu etkilerin sonucu olarak ortaya çıkan katı atıklarda
çevre üzerinde önemli etkilere sebep olmaktadır. Katı atıklar tüketici temelli
ekonomik yaşam tarzının önemli ve zararlı bir sonucudur. Sürdürülebilir enerji
için kentsel katı atık depolama sahalarında oluşan deponi gazları yüksek metan
içeriği nedeniyle enerji üretim sistemlerinde yakıt olarak
kullanılabilmektedirler. Bu çalışmada, küçük ölçekli bir katı atık depolama
sahasında 30 kW gücünde mikro-türbin kullanarak elektrik enerjisi üretimi
teknik ve ekonomik olarak incelenmiştir. Mikro-türbinin yıllık elektrik enerjisi,
üretimi kapasite faktörü 0,8 olduğunda, 210.240 kWh olarak hesaplanmıştır.
Türbin özgül maliyetine göre hesaplanan elektrik enerjisinin bir değere
getirilmiş maliyeti % 8 indirim oranı için 0.079 $ olarak belirlenmiştir.
Çalışmadan elde edilen sonuçlar, küçük ölçekli katı atık depolama sahasında 30
kW gücünde mikro-türbin kullanılarak elektrik enerjisi üretiminin teknik ve
ekonomik olarak uygun olduğunu göstermiştir.

WASTE TO ENERGY: EXPLOITATION OF LANDFILL GAS IN MICRO-TURBINES

Abstract

   The energy consumption has been
increasing due to social and economic development, risen up of people’s living
standard and also population growth in the world. In addition, solid wastes
occurring as result of these driven causes have emerging as a significant
pressure on environment. Solid waste is the most visible and pernicious
by-product of consumer-based economic lifestyle. The Municipal Solid Waste
(MSW) is the principal volume of residues produced worldwide. Landfill gas
which is generated by means of MSW due to considerable methane content can be
used as fuel in the energy generation machines for sustainable energy
production. In this study, a technical and economic study using micro-turbine
of the 30 kW power for utilization in small size landfill areas is presented.
Annual electricity generation of micro-turbine considered is 210,240 kWh when
capacity factor is 0.80. Economical evaluation for micro-turbine was made using
the Levelized Cost of Electricity method. The electricity cost is predicted to
be US$0.079 for 8% discount rate and the considered turbine-specific cost. The
results show that electricity production based on biogas with micro-turbine of
30 kW power is realistic in terms of techno-economic for the small size
landfill area.
