Research on pollutant emissions of catalytic combustion burner of natural gas start-up

This article discussed exhaust gas pollutant emissions characteristics of the combustion of rich natural gas-air mixtures in Pd metal based honeycomb monoliths in burner VI during the period of start-up process. The burner VI need to be ignited by gas phase combustion with the excessive air coefficient (α) at 1.3. Before it reached the steady state of catalyst, the exhaust gas pollutant emissions were measured by the analyzers every 30 seconds. CO content of exhaust gas ascended with the increasing of time before local catalytic ignition. It can be known that the conversion of homogenous combustion is lower than that of catalytic combustion.
