An industrial burner uses natural gas as fuel. The natural gas consists primarily of CH4 with small quantities of several other light hydrocarbons and can be represented as C1.16H4.32 To achieve low emissions of oxides of nitrogen, the burner operates lean at equivalence ratio of 0.4. Assume complete combustion and answer the following questions. i) What is the operating air-fuel ratio (i.e. mass air/mass of fuel)? [6 marks] ii) What is the percent excess air in the combustion products? [3 marks] iii) What is the oxygen (O2) mole fraction in the combustion products? [6 marks]

Question
An industrial burner uses natural gas as fuel. The natural gas consists primarily of CH4
with small quantities of several other light hydrocarbons and can be represented as
C1.16H4.32 To achieve low emissions of oxides of nitrogen, the burner operates lean at
equivalence ratio of 0.4. Assume complete combustion and answer the following
questions.
i) What is the operating air-fuel ratio (i.e. mass air/mass of fuel)? [6 marks]
ii) What is the percent excess air in the combustion products? [3 marks]
iii) What is the oxygen (O2) mole fraction in the combustion products?
