Waters, A M; Himmel, R L

The report discusses studies aimed at reducing the NOx emissions from gas-fired furnaces and water heaters by minor modifications of the combustion system, such as derate, primary air adjustment and excess air minimization. The influence of NOx emission reduction and seasonal efficiency improvement on the NOx emission factor in nanograms/joule heat output are discussed. Emission inventory for gas-fired clothes dryers and a pulse combustion type boiler are presented. Further studies of the effect of burner design on NOx emission is discussed as in the effect of changes in the fuel gas composition. Finally, a report on proper sampling of a gas-fired appliance is reviewed and the highlights presented in this report.
