Abstract
This article discussed the thermal efficiency, stability and pollutant emissions characteristics of the combustion of lean natural gas-air mixtures in Pd
metal based honeycomb monoliths by means of experiments on a practical burner V. The chemistry at work in the monoliths was then investigated
by the stagnation point flow reactor( SPFR), a fundamental experimental reactor. It was found that catalytic combustion inhibited the extent of
gas-phase oxidation and increased the surface temperature of homogeneous ignition. According to the applications of catalytic combustion in the
condenser boiler, the data of catalytic combustion condenser boiler V were measured at atmospheric temperature and pressure. The study also
showed that more than 95% of its thermal efficiency was found possible while preserving near zero pollutant emissions. For all the catalysts tested,
flow rates, and mixture compositions of natural gas and air used here, neither CO (the unburned fuel) nor NOx were detected as long as surface
combustion was taking place.
