Emissions for combustion systems continue to pose major environmental and health challenges, hence the need to regulate these emissions. The aim of this work is to determine the temperatures and the associated level of emissions for a gas burner. The burner which was designed and constructed for furnace firing is a forced draught, pre-mix type and has a power rating of 162.7kW. The experiment was carried out on a burner test-rig which was also designed and constructed. Temperature readings for five points along the flame length in the combustion chamber were taken using k-type thermocouples while an exhaust gas analyzer was employed for the emissions measurements from the chimney. The gas flow rates for the burner were varied for the test. The maximum temperature obtained from the closed test was 1273 °C at full gas valve opening. The emissions measurements obtained were compared with some established standards and the levels of emissions were found to be close to the established standard. An optimum operating condition at ½ gas valve opening with a temperature of 1094 °C was also established for the burner based on the comparisons made. The burner can thus be used for high temperature applications while maintaining low level of emissions.
