Question

The percentage composition of a sample of bituminous coal was found to be as under: C = 75.4%; H = 5.3%; O = 12.6%; N = 3.2%; S = 1.3% and Ash = rest. Calculate the minimum weight of air necessary for complete combustion of 1 kg of coal and percentage composition of dry products of combustion by weight:

Step 1

Given the percentage composition of the coal, we can calculate the mass of each element in 1 kg (1000 g) of coal. - Carbon (C) = 75.4% of 1000g = 754g - Hydrogen (H) = 5.3% of 1000g = 53g - Oxygen (O) = 12.6% of 1000g = 126g - Nitrogen (N) = 3.2% of 1000g = 32g - Show more…
