Prediction of ash fusion temperatures by using the chemical composition of the ash has previously been conducted only with linear correlations. In this study, a new technique is presented for predicting the fusibility temperatures of ash. Non-linear correlations are developed by using the chemical composition of ash (eight oxides) and coal parameters (ash content, specific gravity, Hardgrove index and mineral matter content). Regression analyses are conducted using information for Turkish lignites. Regression coefficients and variances of non-linear and linear correlations are compared. The results show that the non-linear correlations are superior to linear correlations for estimating ash fusion temperatures.

Comparison of single particle combustion behaviours of raw and torrefied biomass with Turkish lignites Magalhaes, Duarte; Panahi, Aidin; Kazanç Özerinç, Feyza; Levendis, Yiannis A. (Elsevier BV, 2019-04-01) This study investigated the combustion behaviour of single pulverized biomass and lignite coal particles under high temperature-high heating rate conditions. Selected fuels included three important agricultural residues in Turkey (olive residue, almond shell, and hazelnut shell), and two lignite coals from the regions of Tuncbilek and Soma in Turkey. Biomass fuels were either raw or torrefied at 275 degrees C for 30 min in nitrogen. The biomass fuels were sieved to a size cut of 212-300 mu m, and the coals ...
Improvements on combustion properties of asphaltite and correlation of activation energies with combustion results Hicyilmaz, C; Altun, Naci Emre (Elsevier BV, 2006-06-01) Processing of Sirnak Asphaltite sample by gravity and flotation concentration methods was investigated to decrease its ash content. Finely disseminated inorganic constituents of asphaltite revealed the difficulty of operation. Ash content of asphaltite was reduced from 44.86% to 31.44% by gravity concentration method with a 75% combustible recovery. On the other hand, it was possible to reduce ash content to 24% by flotation with almost same combustible recovery. Combustion characterization of raw and impro...
Modeling and numerical simulations of lignite char gasification with CO2: The effect of gasification parameters on internal transport phenomena Karaca, Mehmet; Kaya, Deniz; Yozgatlıgil, Ahmet; Gokalp, Iskender (Elsevier BV, 2021-02-01) The purpose of this study is to develop an experimental data-based char particle gasification model in order to assess the effects of particle size, gasification temperature and char generation heating rate on global gasification parameters. Also, the effect of initial porosity is observed by performing parametrical numerical simulations. A continuum-based model is used to solve the gasification inside a char particle and within the external boundary layer. The intrinsic rate of CO2 gasification reaction is...
A study on the effects of catalysts on pyrolysis and combustion characteristics of Turkish lignite in oxy-fuel conditions ABBASI-ATIBEH, Ehsan; Yozgatlıgil, Ahmet (Elsevier BV, 2014-01-01) The catalytic pyrolysis and combustion characteristics of low calorific value Turkish lignite in various ambient conditions were explored and the evolution of gases during pyrolysis tests was examined using a Thermogravimetric Analyzer coupled with a Fourier Transform Infrared spectrometer (TGA-FTIR). Potassium carbonate (K2CO3), calcium hydroxide (Ca(OH)(2)) and iron (III) oxide (Fe2O3) were employed as precursors of the catalysts and compared to the Raw-form (no catalyst added) to investigate the effects ...
New observations of isolated ethanol droplet flames in microgravity conditions Park, Seul-Hyun; Choi, Seuk-Cheun; Choi, Mun Young; Yozgatlıgil, Ahmet (Informa UK Limited, 2008-01-01) Spherically symmetric ethanol droplet combustion experiments were performed to investigate the influence of initial droplet diameter, ambient pressure and inert substitution on the burning and sooting behaviors of ethanol droplet flames. Experiments were performed using the 2.2 sec reduced-gravity droptower facilities at the NASA Glenn Research Center. Noting the importance of transport characteristics of heat and species and their attendant effects on flame temperature and residence time on the sooting mec...
