To establish environmentally friendly small-scale CHP units, a concept with serial connection of two SOFC stacks and an electrical efficiency of up to 50 % was developed. The underlying idea of the STAGE-SOFC concept is to couple a small exothermal CPOX stage with a larger endothermal steam reforming stage. This complete new system layout was validated by system modelling, CFD simulations of single components, experimental investigation of reformer performance and testing of a complete 5 kW prototype system for more than 600 hours under various parameters and loads. On basis of these results an improved second prototype was designed for long-term tests under real operating conditions.

“…The results of experimental and numerical investigations illustrated approximately the same maximum temperature and distribution into the burner. 14 There is a wide range of H 2 /CO ratios, which has a significant impact on combustion and extinction characteristics, making the design of syngas combustor and operating with syngas fuels difficult. Syngas could represent an expansion of the flame stability limit due to the presence of hydrogen, especially for hydrogen enriched syngas fuels.…”

This paper discusses the effect of burning syngas in a configuration similar to that of the BERL (Burner Engineering Research Laboratory) 300 KW swirl-stabilized combustor which has previously been used with methane as a fuel. Due to the axisymmetric configuration, only 15° from the burner angle is studied with periodic boundary. The model adopts RANS (Reynolds Averaged Navier–Stokes) technique including a realizable k-ε turbulent scheme. The non-premixed combustion model used is based on applying flamelet concept. The study shows that the structure of the flame is affected with changing the burner quarl angle and the inlet air swirl number. The detailed parametric study of this synthetic fuel in the BERL paradigm relates easily to the accumulated experimental and numerical studies available in this configuration and then acquiring add noval value to the present work. The study also shows the presence of different recirculation zones, one of which is central recirculation zone and an external recirculation zone. When increasing quarl angle, the central recirculation zone is shifted outward and the turbulent interaction between the central fuel jet and the recirculation zone induces small vortices between these two flow patterns. On the other hand, the effect of flue gas recirculation and air staging into the burner on the reduction of NOx formation is discussed. The flue gas data show that FGR reduces NOx emissions significantly while having no influence on flame stability, total combustion efficiency, or CO emissions. Changes in fuel composition are also taken into account. The results reveal that when the hydrogen blending in the fuel increases, the temperature rises.

Bu çalışmada, tasarlanıp imal edilmiş bir biyogaz reaktöründen elde edilen biyogazın yanma karakteristikleri hakkında sayısal çalışmalar yürütülmüştür. Biyogaz reaktöründen elde edilen gaz, sisteme uyumlu yakma sisteminde yakılarak, yanma sonu emisyon değerleri ve sıcaklık dağılımları sayısal olarak araştırılmıştır. Yapılan araştırmalarda elde edilen deneysel sonuçlar, sayısal sonuçlarla karşılaştırılmış olup sıcaklık dağılımı bakımından önemli derecede uyum olduğu tespit edilmiştir. Sayısal modellemelerde k-Ɛ standard türbülans modeli, P-1 radyasyon modeli ve PDF/Mixture Fraction yanma modeli kullanılmıştır. Modellemelerde, hacimce % 55 CH4-% 45 CO2 ve % 45 CH4-% 55 CO2 karışımlı biyogazlar modellenmiş, sıcaklık ve emisyon dağılımları Ansys Fluent ticari kodu ile tahmin edilmiştir. Elde edilen tahmin sonuçları, % 45 CH4-% 55 CO2 karışımlı biyogazın sıcaklık seviyelerinin yanma odası giriş bölgelerinde daha düşük, yanma odası çıkışına doğru daha yüksek olduğunu göstermiştir. CO2 ve H2O tahminlerinde ise, bünyesinde daha fazla miktarda CO2 bulunduran biyogaz için CO2 seviyeleri ve H2O seviyeleri daha yüksek olarak belirlenmiştir.
