Combustion and Co-Combustion characteristics of torrefied poultry litter with lignite

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 poultry litter was also investigated.


Combustion characteristics of lignite and oil shale samples by thermal analysis techniques
Kök, Mustafa Verşan; Keskin, C; Madarasz, J; Bagci, S (2004-01-01)
In this research thermal analysis and kinetics of ten lignite's and two oil shale samples of different origin were performed using a TA 2960 thermal analysis system with themogravimetry (TG/DTG) and differential al analysis (DTA) modules. Experiments were performed with a sample size of similar to10 mg, heating rate of 10degreesC min(-1). Flow rate was kept constant (10 L h(-1)) in the temperature range of 20-900degreesC. Mainly three different reaction regions were observed in most of the samples studied. ...
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...
Non-isothermal DSC and TG/DTG analysis of the combustion of silopi asphaltites
Kök, Mustafa Verşan (2007-06-01)
In this research, non-isothermal combustion and kinetics of Silopi (Turkey) asphaltite samples were investigated by differential scanning calorimetry (DSC) and thermogravimetry (TG/DTG). A sample size of 10 mg, heating rates of 5, 10, 15 and 200C min(-1) were used in the temperature range of 20-600 degrees C, under air atmosphere. Two reaction regions were observed in DSC curves. The first region is due to the evaporation of moisture in asphaltite sample whereas, release of volatile matter and burning of ca...
Combustion characteristics and kinetics of diesel and canola oil samples
Kök, Mustafa Verşan (2016-01-01)
In this study, combustion and pyrolysis behavior of diesel and canola oil is investigated using thermal analysis techniques known as thermogravimetry (TG-DTG) and differential scanning calorimetry (DSC) at different heating rates. Reaction regions, peak temperatures, mass loss, heat flow rates, ignition temperatures, and specific heat of diesel and canola oil samples are determined using TG-DTG and DSC data. It was observed that as the heating rate of the reactions increased, peak temperatures of the reacti...
Thermal behavior and kinetics of crude oils at low heating rates by differential scanning calorimeter
Kök, Mustafa Verşan (2012-04-01)
The objective of this research was to investigate thermal behavior and kinetics of different origin crude oils in limestone matrix by differential scanning calorimeter (DSC) at low heating rates. In DSC experiments, three distinct reaction regions were identified in all of the crude oil + limestone mixtures known as low temperature oxidation (LTO), fuel deposition (FD) and high temperature oxidation (HTO) respectively. Kinetic analysis of the crude oil samples was determined by different models known as AST...
