THERMOGRAVIMETRIK ANALYSIS OF WASTE BIOMASS PELLET AND COMBUSTION KINETICS

Abstract

In the present study, combustion properties and kinetics of agricultural residue stalks (sunflower, rice, corn, and wheat) and their respective pellet were investigated using thermogravimetric system (TG). Stalks pellet made from mixture of wheat (78%), corn (13 %), sunflower (7 %) and rice (1 %) with Euqhorbia denroides (1 %) as a binder. Ingraham–Marrier, Arrhenius, and Coats-Redfern non-isothermal kinetic models were applied to calculate the kinetic parameters. The Ingraham–Marrier model shows better prediction than the Arrhenius and Coats-Redfern models, and satisfactorily described the combustion of agricultural samples

ATIK BİYOKÜTLE PELLETİNİN TERMOGRAVİMETRİK ANALİZİ VE YANMA KİNETİĞİ

Abstract

Bu çalışmada; tarımsal kalıntı saplarından (ayçiçeği, pirinç, mısır ve buğday) üretilen pelletin yanma karakteristiği ve kinetiği termogravimetrik analiz (TG) kullanılarak incelenmiştir. Pellet, bağlayıcı madde olarak Euqhorbia denroides (% 1) ile buğday (% 78) , mısır (% 13) , ayçiçeği (% 7) ve pirinç ( % 1) karışımı ile oluşturulmaktadır. Ingraham-Marrier, Arrhenius ve Coats-Redfern izotermal olmayan kinetik modeller kinetik parametreleri hesaplamak için uygulanmıştır. Ingraham - Marrier modeli, Arrhenius ve Coats-Redfern modellerine göre tarımsal numunelerin yanma özelliklerini daha iyi bir şekilde tanımlamaktadır
