LPG Yakıt Kullanarak Farklı Kombilerin Çevresel Etkilerinin Araştırılması

Binaların ısıtılması ve sıcak su temini genellikle kombiler yardımıyla yapılmaktadır. Kombilerin farklı tipleri mevcuttur. Son yıllarda konvansiyonel kombilere göre yüksek verimli yoğuşmalı tip kombiler piyasaya sürülmüştür. Bu çalışmada, kombi tipinin kirletici gaz emisyonu üzerindeki etkisi deneysel olarak incelenmiştir. Deneylerde yoğuşmalı, tam yoğuşmalı ve konvansiyonel tip kombi olarak üç farklı kombi kullanılmıştır. Ayrıca, sıcaklığın etkisini belirlemek için deneyler çeşitli sıcak su sıcaklıklarında gerçekleştirilmiştir. Elde edilen sonuçlara göre, yoğuşmalı ve tam yoğuşmalı kombiler tüm sıcaklıklarda NO, NOx ve SO2, gaz emisyonlarını önemli ölçüde azaltmıştır.

Investigating environmental effects of different combi boilers using LPG

Space heating and hot water supplying were usually done by utilizing combi boilers. Various kinds of combi boilers are available. In the last years condensing type combi boilers have been introduced that have high efficiency in comparison to conventional one. In the present study the impact of combi boiler type on pollutant gas emissions was experimentally investigated. Three various combi boiler including condensing, full condensing and conventional type combi boilers were utilized in the experiments. Moreover, the experiments were conducted in various outlet hot water temperatures to determine the effect of temperature. The achieved findings indicated that in all temperatures utilizing condensing and full condensing combi boilers decreased NO, NOx and SO2, gas emissions considerably.
