A methodology has been developed to investigate the factors affecting both gaseous emissions (particularly NO2) and thermal efficiency of natural gas‐fired burners for domestic cooking appliances. Many factors are reported, in the literature, to affect the NO2 emission rate and the reported effects are sometimes contradictory, suggesting that these studies may not be definitive. The methodology reported here is designed to produce a definitive study or, at least, to allow the identification of results that are not definitive and therefore require further investigation. An experimental rig has been developed and its performance has been well‐characterized to select operating conditions that minimize the experimental error. The gas sampling and analysis train tested favourably in an international inter‐laboratory comparison. In developing the methodology, hydrocarbon leakage into the air surrounding the burner and flame impingement on the load were found to affect the results, so these factors were studied separately.
