Correlations for CO{sub 2} production from combustion of Turkish coal
- Marmara Univ., Istanbul (Turkey)
Carbon dioxide is identified as the major contributor to greenhouse gas emissions. About 75% of the anthropogenic CO{sub 2} emissions are due to energy use, and primarily due to fossil-fuel combustion. Future patterns of energy use will dominate the global climate change. Within this frame, comparative evaluation of various carbon-based primary energy sources and related utilization options is of utmost importance. The amount of CO{sub 2} emission per unit energy production is considered as the mutual basis of evaluation among the fuel options. In this study, 39 Turkish coals were selected to represent the broad spectrum of Turkish coal characteristics. The lower heating values of the samples range from 6.8 to 30.6 MJ/kg on the as-received basis. The corresponding higher heating value range is 8.2 to 31.6 MJ/kg. The volatile matter to fixed carbon ratios of the selected coals change between 0.520 and 2.05 whereas the C to H weight ratios of dry coals cover a range from 16.4 to 9.8. The exact amount of CO{sub 2} emission per unit heating value is calculated from experimental data. The analysis of the results indicates that linear correlations exist between CO{sub 2} emissions per unit amount lower or higher heating value and the inverse of heating values. The calculated standard errors of estimate are within acceptable limits. The average and maximum errors are 3% and 11%, respectively. The developed formulas are applied to different ranks of coal from Turkey and abroad and results are interpreted.
