Thermogravimetric assessment of combustion characteristics of blends of a coal with different biomass chars

摘要: Abstract In connection to future energy demand and fossil fuel crisis particularly in India, biomass is gaining its importance for possible use as co-fuel. India varieties of products are available which do have tremendous potentiality co-combustion with pulverized coal. Based on the emerging need, detailed investigations felt necessary examine compatibility different kind coal select suitable blend composition(s) before utilizing those utility operation co-fuels. This study elaborates lab scale findings combustion experiments DSC–TGA apparatus a typical Indian coal, two samples low temperature chars (300 450 °C) well ‘blends coal’. Conventional TGA parameters, activation ignition index blends were estimated provided elaborate information their basic features. Results non-isothermal studies general depict that containing less than 50% char better performing compared higher content. Lowering improvement reactivity major zone also observed coal/biomass-char blends. Improvement 300 °C over expected weighted mean values was noticed. Such attempts may help identify appropriate biomass-type, proportion given derive some specific advantages respect particular practice.
