A boiler is fired by light grade fuel oil has an output of 90kW and an efficiency of 88%. The analysis by mass of the constituents of the oil is Carbon 86.2%, Hydrogen 12.4% and Sulphur 1.4%. Data Ambient temperature =15C Density of oxygen at ambient condition =1.361kg/m3 Density of air at ambient condition =1.234kg/m3 Net calorific value of the fuel oil is 40.5MJ/kg Given Density of substance =22.28molecularmass Calculate a. Find the stoichiometric volume of air for complete combustion of 1kg of the oil. b. Find the actual volume of air assuming 20% excess is need for complete combustion. c. Find the volumetric air fuel ratio based upon the actual volume of air required. d. Determine the emission of carbon dioxide in the products of combustion when the boiler is working at full load. Assume that the air for combustion has negligible CO2 content. e. If the plant runs at an equivalent full load for 939 hours/year, how much CO2 would this plant produce annually?
