STUDY ON THE CHARACTERISTICS OF CATALYTIC COMBUSTION FURNACE OF NATURAL GAS AND INFLUENCE OF ITS EXHAUST GAS TO PLANT

This article discussed the radiation and pollutant emissions characteristics of the catalytic combustion furnace based the combustion of lean natural gas-air mixtures in catalytic honeycomb monoliths and the influence of its exhaust gas on schefflera plants growth by means of theory and experiments. The radiation efficiency of the monolith alone varied from approximately 20% to 40%. The glazed tiles heated by the catalytic combustion furnace are more fine and glossy than that of conventional ones. Schefflera plants in experimental group in a greenhouse filling with catalytic combustion exhaust gas. On contrary, schefflera plants in control group stay in indoor environment. The result showed that schefflera plants in experimental group grow faster than that in control group, even greener. The content of pollutants in the exhaust gas of furnace and the date of the parameter of temperature, humidity and the concentration of CO2 in greenhouse were measured. Catalytic combustion as a developing technology could make the pollutant emissions (CO and NOX) to near zero. The exhaust gas with high CO2 concentration could promote the growth of plants.
