In this study, combustion and co-combustion characteristics of three biomass fuels and three Turkish lignite coals were investigated by using a thermo gravimetric analyzer. There are just a few studies investigating the co-combustion characteristics of coal and biomass, and the synergistic effect of their various combinations on the peak temperatures and burnout times.


Investigation of alternative biomass fuels and Turkish lignites at high heating rate pyrolysis and combustion conditions
Magalhaes, Duarte; Kazanç Özerinç, Feyza; Yozgatlıgil, Ahmet; Department of Mechanical Engineering (2021-2-12)
The objective of this work was to investigate alternative Turkish fuels fortheir ignition, combustion, pyrolysis, and gasification behavior and to select alternative fuels for co-firing, co-pyrolysis, and co-gasification applications based on low and high heating rate experimental results. Agricultural biomass (olive residue, almond shell, and hazelnut shell)and Turkish lignites (Tunçbilek, and Soma) were chosen as the feedstocks. Severalexperimental rigs used such as thermogravi...
Investigation of combustion of lignite and torrefied biomass in a thermogravimetric analyzer (TGA) and in a circulating fluidized bed (CFB) under oxy-fuel combustion conditions
Barzegar, Ramin; Yozgatlıgil, Ahmet; Department of Mechanical Engineering (2019)
In this study, the combustion of Turkish lignites (Orhaneli and Soma), torrefied woodchip, and their blends was studied under oxygen-enriched and oxy-fuel combustion conditions in a thermogravimetric analyzer. The iso-conversional kinetic methods were used to estimate the Arrhenius parameters and the uncertainty assessments associated with the kinetic calculations were considered. The co-combustion experiments showed a synergetic effect between the biomass samples and Orhaneli lignite. Based on the obtained...
Characterization of lignocellulose biomass and model compounds by thermogravimetry
Kök, Mustafa Verşan (Informa UK Limited, 2017-01-01)
In this research, combustion characteristics of lignocellulose biomass (hazelnut shell) and three main components (cellulose, hemicellulose, and lignin) were investigated using thermogravimetry (TGA-DTG) technique at different heating rates. The ignition, peak, burn-out temperatures, and the heat liberation of lignocellulose biomass and three main components were also measured. Two different model-free kinetic methods, known as Ozawa-Flynn-Wall (OFW) and Kissinger-Akahira-Sunose (KAS), were used in order to...

The combustion characteristics of petcoke and imported coal and their respective chars under oxy-fuel (21% O-2/79% CO2) and oxygen-enriched oxy-fuel (30% O-2/70% CO2) environments were investigated by using non-isothermal thermogravimetric method coupled with a Fourier transform infrared spectrometer. Experimental results reveal that at elevated oxygen levels, profiles shift to lower temperature zone, peak and burnout temperatures decrease, weight loss rate increases significantly, and complete combustion i...
Influence of water vapour on high temperature oxidation of steels used in petroleum refinery heaters
Sultan, A.; Karakaya, İshak; Erdogan, M. (2012-02-01)
The oxidation behaviours of three different steels used in the construction of petroleum refinery heaters were investigated by thermogravimetric analysis (TGA) technique. C-5, P-11 and P-22 steel samples were tested in two different environments: air and CO2+2H2O+7.52N2, a gas composition which simulates the combustion products of natural gas, at 450 and 500 degrees C. P-22 steel had the best oxidation resistance at both temperatures in air. In CO2+2H2O+7.52N2 environment, the oxidations of all the steels w...
