Effects Of Mineral Composite Materials For Far Infrared Radiation On Oil Consumption And Air Pollutants Emission Of Oil-Burning Boiler

Aimed at the petroleum resources shortage and environmental pollution, new types of mineral composite materials with far infrared radiation were successfully prepared to be applied to oil-burning boiler, which could improve the physicochemical properties of fuel oil, enhance the combustion efficiency and reduce the air pollutant emission. The far infrared radiation performance of the mineral composite materials and their influence on the oil consumption and air pollutant emission were systematically investigated in this thesis, especially the influence mechanism of mineral composite materials on the combustion of fuel oil.The ceramic materials with far infrared radiation were prepared using tourmaline, rare earth and clay as raw materials. When the proportion of mineral material, rare earths and clay was 15:1:4, the ceramic materials heat-treated at 900℃for 2h exhibited the highest infrared radiance of 0.91. When this material used in RBS·VH-1.5 boiler, the oil-saving ratio could reach 1.23%, and the contents of CO and NO in the exhaust gas could reach 25.6% and 9.2%, respectively.The organic/inorganic composite materials with far infrared radiation were prepared using tourmaline, rare earth and resin as raw materials. The far infrared radiation performance of the composite materials and their influence on the oil consumption and air pollutant emission were investigated. The experiment results showed that the as-prepared composite materials had the highest infrared radiance of 0.93 when the ratio of mineral material to resin was 4:6. The oil-saving ratio of the boiler using this composite material could reach 3.78%, and the contents of CO and NO in the exhaust gas were 15.9% and 14.5%, respectively.The influence mechanism of mineral composite materials on the improvement of combustion efficiency and reduction of air pollutant emission were studied in this thesis. It was believed that the far infrared radiated by the mineral composite materials could enhance the molecular energy and reduce the surface tension of diesel oil, thus leading to the improvement of its atomization quality and the reduction of air pollutant emission.
