Problem 19P

In a combustion chamber, ethane (C2H6) is burned at a rate of 8 kg/h with air that enters the combustion chamber at a rate of 176 kg/h. Determine the percentage of excess air used during this process.

Step by step solution Step 1 of 3Write the combustion reaction of ethane as follows ......(1)Here,ethane is ,stoichiometric coefficient for air is ,oxygen is ,nitrogen is ,carbondioxide is ,and water isThe stoichiometric coefficient for air is calculated by balancing oxygen on both sides of thereaction.From equation(1),calculate the stoichiometric coefficient for air by balancingSubstitute 3.5 for in equation(1)
