The Use of an Emission Analyzer to Demonstrate Basic Principles


  • Keith B. Lodge University of Minnesota


Laboratory experiments using a burner fed with known flows of natural gas, a makeshift flue, and an emission analyzer that measures the volume fractions of oxygen and nitric oxide in the exiting flue gases are described. The results are used to demonstrate basic stoichiometry and kinetics; the levels of carbon dioxide and excess air in the flue gas are calculated, and the temperatures that must exist for the formation of nitric oxide are estimated.
