Research on exhaust gas temperature inside catalytic honeycomb monolith channel of natural gas burner start-up

摘要

This article discussed exhaust gas temperature and pollutant emissions characteristics of the combustion of rich natural gas-air mixtures in Pd metal based honeycomb monoliths in burner during the period of start-up process. The burner need to be ignited by gas phase combustion with the excessive air coefficient (a) at 1.3. The experimental results in catalytic monolith can be explained from SPFR. In this experiment, exhaust gas temperature and pollutant emissions were measured by thermocouple K of diameter 0.5 and the analyser every 1 minute, respectively. The finding would be applied for industrial catalytic combustion process start-up.
