STUDY ON FLOW AND TEMPERATURE BEHAVIOR OF CATALYTIC HONEYCOMB MONOLITH COMBUSTION FURNACE OF NATURAL GAS TO PROPERTIES OF GLAZED TILES

摘要

This article discussed flow and temperature characteristics of the catalytic combustion furnace based the combustion of lean natural gas-air mixtures in catalytic honeycomb monoliths. Catalytic combustion as a developing technology could make the pollutant emissions (CO and NO X ) to near zero. Within the porous structure, the reactions then take place on the catalytic sites. A heterogeneous catalytic process includes more than one phase. Usually the catalyst is a solid and the reactants and products are in liquid or gaseous form. According to the applications of low- carbon catalytic combustion furnace, heating glazed tiles with pure solid texture, rich melodic style and glamorous colors were obtained. It was found pleasing to both the eye and the mind. Also the water absorption and frost resistance of glazed tiles were accorded with Chinese national standard. It is feasible to apply the glazed tiles heated by the catalytic combustion furnace to the architectural decoration of buildings.
