The afterburning of carbon monoxide in natural gas combustion gases in the presence of catalytic ceramic coatings

Morel S.

Journal of Power Technologies

Vol. 92, nr 2

109--114

Some more important types of environmental noxiousness connected with the emission of CO and other toxic gases have been characterized. Methods are detailed, which permit the reduction of pollutant emission from the burning processes, of which catalytic afterburning is emphasized. The results of studies are reported, concerning the catalytic effect of ceramic coatings as plasma sprayed onto burning space containing surfaces on the variation of combustion gas parameters. The catalytic afterburning processes were carried out in tube furnaces by burning coke-oven gas, in bathroom-type water heaters where natural gas was burnt, and in a model chamber ended with combustion gas ducts filled with ceramic shapes having sprayed catalytic coatings. The obtained measurement results confirm the purposefulness of using the burning-process catalyzing coatings.
