여러 $CO_2-O_2$ 혼합기체에서 인도산 분말숯의 연소반응실험을 수행하였다. 샘플을 분쇄하여 58 마이크론보다 작은 채로 거르고 질소분위기에서 숯으로 만들었다. CPRI 방갈로에 있는 열분석기 (TGA-50)을 사용해 실험을 하였다. $CO_2-O_2$ 혼합기체는 몰비로 (80-20, 60-40, 40-60, 20-80)을 사용하였다. 활성화에너지 (E) 및 지수앞자리인자 (A)을 통합접근 및 수정된 Arrhenius식을 사용해 계산하였다.
Experimental work was carried out to study the combustion kinetics of the Indian coal-char in the varying mixture of carbon dioxide-oxygen ($CO_2-O_2$). The coal sample was pulverized and sieved to less than 58 microns and charred using volatile furnace by passing the nitrogen gas. The experiments were carried out using the Thermo Gravimetric Analyzer (TGA-50) at CPRI, Bangalore, different proportions of ($CO_2-O_2$) gas was allowed in to the TGA-50 (80-20, 60-40, 40-60, 20-80) mole basis were used to study the combustion kinetics of coal Isothermally, kinetic parameters like Activation energy (E) and the pre-exponential factors (A) are calculated using the unification approach and modified Arrhenius equation.
