【摘要】 采用多孔介质预混燃烧技术设计了一种环保燃气灶具,对其燃烧污染物排放进行实验研究,证明多孔介质全预混燃烧技术能使家用燃气灶具烟气中NO_x排放量降到5×10^-6以下。对各种不同材料、孔径、厚度的多孔金属介质及3种型号的引射器组合进行了对比研究,得出PPI为35、厚度为4mm的红外涂层铁铬铝多孔金属介质用于家用液化石油气燃气灶,综合性能优于其它材料的结论。更多还原

【Abstract】 An environment friendly gas cooker of porous metal with premixed combustion technology was designd. The result shows that NO_x emissions could be reduced to less than 5 10^-6.Nine kinds of porous metal with dif- ferent materials,pore size and thickness and three types of injectors were compared.PPI 35,4mm thick,Fe- CrAl with infrared coating is the optimum material for burn head.更多还原
