WebOne kg of carbon burning to CO2 liberates 35000 kJ, and one kg of hydrogen liberates 143000 kj, when the products of combustion are cooled down to 25°C. Higher calorific value = 0.85 × 35000 + 0.125 × 143000 = 47750 kJ/kg. Lower calorific value = 47750 – 9 × 0.125 × 2442 = 45000 kJ/kg. WebJun 1, 2015 · The worldwide production of coal combustion products (in 2010) was approximately 780 million tons [3]. Unburned carbon (UC) levels in ash varies greatly; however, even if average unburned carbon content in all these ashes was as low as 1%, it would constitute about 8 million tons of this waste material produced annually.
WebThe generalised cross-validation (GCV) index was used to evaluate each sub-range model. The general expression of GCV is: (3) G C V = M S E (1 − k + 0.5 c (k − 1) n) where k is the number of basis function, C is the penalty coefficient in the range of [2,4] and n is the number of training observations. 3.2.
