In the present study, combustion mechanisms, thermal kinetics, and phases of combustion were investigated for untreated pine and treated MDF, plywood and particleboard samples. Waste wood samples were combusted in air at 10, 20 and 30 degrees C/min heating rates in TGA. As a result of TG analysis, thermal decomposition of treated samples was observed at lower temperatures as compared to the untreated pine sample because of the catalyzing effects of the chemicals in the samples. Therefore, there were less flammable products, lower weight losses in the main oxidation region, decrease in the max. weight loss temperatures and formation of more char for treated samples as compared to untreated pine sample. In other words, chemicals used during production of these samples lead to decrease in the combustibility of the treated samples. Thermal kinetic constants for the samples were calculated by using Coats Redfern and Broido Methods. In order to find out the mechanisms responsible for the oxidation of the waste wood samples, six solid state mechanisms of Coats Redfern Method were tested.

Investigation of combustion kinetics of treated and untreated waste wood samples with thermogravimetric analysis
Yorulmaz, Sema Yurdakul; Atımtay, Aysel (2009-07-01)
In the present study, combustion mechanisms, thermal kinetics, and phases of combustion were investigated for waste wood samples (untreated pine and treated MDF, plywood and particleboard). Waste wood samples were combusted in air at 10, 20 and 30 degrees C/min heating rates in TGA. The results of TG analysis have shown that thermal decomposition of treated samples takes place at lower temperatures as compared to the untreated pine sample because of the catalyzing effects of the chemicals in the samples. Th...
Investigation of emissions from thermal oxidation of waste wood samples using spectral methods
YURDAKUL, Sema; Atımtay, Aysel (2015-01-01)
The objective of this study was to investigate the effects of chemical treatment and heating rate on the emissions released from various waste wood samples including untreated pine and chemically treated MDF, plywood and particleboard after thermal treatment. Emission characteristics of the samples were determined in situ by using their FTIR spectra. Some toxic and carcinogenic gases such as formaldehyde, isocyanate, ammonia and phenyl group were detected in emissions from low temperature combustion of trea...
An Investigation of the Kinetics and Oxidative Thermodegradation Properties of Waste Telephone Pole Samples Treated with Metal Salts
Yorulmaz, S. Y.; Atımtay, Aysel (2013-12-02)
In the present study, combustion mechanisms, activation energy, and exponential constants were investigated for natural pine and acid copper chromate impregnated telephone pole. Oxidative thermodegradation was carried out in air environment at different heating rates by using thermogravimetric analysis. In order to calculate thermal kinetics, the Coats Redfern method was used. There were less flammable products, lower weight losses in the main oxidation region, a decrease in the maximum weight loss temperat...
Investigation of combustion characteristics of biomass and coal mixtures in a circulating fluidized bed combustor
Varol, Murat; Atımtay, Ayse; Department of Environmental Engineering (2013)
In this study, combustion and co-combustion tests of Bursa/Orhaneli lignite with two biomass fuels (olive cake and woodchips) were carried out in a laboratory scale Circulating Fluidized Bed (CFB) combustor, 6 m high and 108 mm inside diameter, in order to investigate the effect of excess air ratio (l), secondary air ratio (SAR) and location of secondary air injection along the combustor wall on the emissions. Optimum l and SAR was determined for each test. The flue gas emissions were compared with limits i...
Investigation of co-combustion characteristics of low quality lignite coals and biomass with thermogravimetric analysis
Varol, Murat; Atımtay, Aysel; Bay, B.; Olgun, H. (2010-10-20)
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.
