Magalhaes, Duarte; Kazanç Özerinç, Feyza; Riaza, Juan; Erensoy, Sevgi; Kabakli, Ozde; Chalmers, Hannah (2017-09-01)
This study investigated the combustion behavior and kinetics of Turkish fuels. Two lignite coals from Tuncbilek and Soma region, and olive residue, were used, all within a size range of 106-125 mm. Experiments were performed in a thermogravimetric analyzer (TGA) coupled with a differential thermal analyzer (DTA), under three different heating rates, namely 15, 20, and 40 degrees C/min. Based on the weight loss (TG) and derivative weight loss (DTG) curves, the characteristic temperatures were determined, thr...
Combustion and co-combustion of olive cake and coal in fluidized bed
Varol, Murat; Atımtay, Aysel; Department of Environmental Engineering (2006)
In this study, combustion performances and emission characteristics of olive cake and olive cake+coal mixture are investigated in a bubbling fluidized bed of 102 mm inside diameter and 900 mm height. The average particle sizes of coal and olive cake used in the experiments were 1.57 mm and 1.52 mm, respectively. Flue gas concentrations of O2, CO, SO2, NOx, and total hydrocarbons (CmHn) were measured during combustion experiments. Operational parameters (excess air ratio, secondary air injection) were change...

Combustion and Co-Combustion characteristics of torrefied poultry litter with lignite
Atımtay, Aysel (2020-04-01)
This study investigated the thermal properties and activation energies of raw and torrefied poultry litter samples in the range of 250-300 degrees C by using thermogravimetric analysis (TGA). Four heating rates, 5 degrees C/min, 10 degrees C/min, 20 degrees C/min, and 30 degrees C/min were applied during the thermogravimetric analysis. Furthermore, co-combustion of raw and torrefied poultry litter samples with low-rank Turkish lignite was studied and the effect of the blending ratio on thermal reactivity of...
Combustion behaviour of Turkish lignite in O-2/N-2 and O-2/CO2 mixtures by using TGA-FTIR
Selçuk, Nevin (2011-03-01)
The pyrolysis and combustion behaviour of a low calorific value Turkish lignite with high sulphur and ash content in air and oxy-fuel conditions were investigated by using non-isothermal thermo-gravimetric method (TGA) coupled with Fourier-transform infrared (FTIR) spectrometer. Pyrolysis tests were carried out in nitrogen and carbon dioxide environments which are the main diluting gases of air and oxy-fuel environment, respectively. Pyrolysis results show that weight loss profiles are almost the same up to...
