Calculate the CV of a fuel sample of coal 0.6 g. Water equivalent of calorimeter 2200 g. Increase in temperature = 6.52 °C Ans:GCV= 23906 cal/g

0.6 g of a coal sample with 92% C, 5% hydrogen, and 3% ash, caused a rise in the temperature of 2000 g water by 3.2 °C in a bomb calorimeter experiment. Calculate the GCV and NCV of coal, given. Water equivalent = 200 g. Ans:GCV= 11733.3 cal/g NCV= 11469.2 cal/g

One coal sample was analyzed and showed 90% C, 8% hydrogen, and 2% ash. 2.0 gof this coal sample was burned in a bomb calorimeter and the temperature of 2.5Kg water was increased from 25 to 35°C. Calculate the GCV and NCV of coal. Given:Water equivalents the instrument and the latent heat of vaporization are 1500 gand 580 cal/g, respectively.

2 kg of a coal sample was burnt in a bomb calorimeter. The heat liberated was estimated and found to be 14114 kcal. Calculate the calorific value of the coal sample.a.14114 kcal /kgb.7057 kcal/kgc.7057 cal/gd.14114 cal /g

Explain in detail with a suitable diagram how you will determine the GCV and NCVof a given coal sample.

For the given energy flow diagram, If the calorific value of coal is 4800 kcal/kg, the amount of coal needed annually is 7413 kg 1662 kg 3981 kg 2463 kg
