Scenario You are nearing to the end an engineering apprenticeship in a reactor engineering department and as a designer you are presented with eight tasks related to combustion of fuels, experimental tests to find calorific value and properties of steam. The chief designer wants to tests your knowledge in combustion of fuels steam plant and property of steams. To prove what you know about the topic you should answer the following tasks.
TASK 1 The chemical analysis of a sample of solid fuel shows it to contain 80.6% carbon, 2.8% hydrogen and 1.1% sulphur. The remainder is incombustible material which remains as ash. Determine (i) the oxygen required for complete combustion of each of the combustible elements per kilogram of fuel and (ii) the theoretical mass of air required for complete combustion per kilogram of the fuel. The oxygen content of air by mass is 23%.
