摘　　要：介绍了2种热流方向的KP1型城市污泥烧结页岩多孔砖热工参数的数值计算,分别采用ANSYS有限元模拟计算组合材料平均热阻方法,阐述了该方法基本原理和具体公式,并对模拟计算结果进行了对比分析。结果表明,砖体条面传热途径与顶面传热途径的墙体传热系数K分别为1.317、1.067 W/(m2·K),均符合JGJ 75—2012中小于1.5 W/(m2·K)的规定,满足建筑节能50%的要求。与组合材料平均热阻计算对比,砖体条面导热系数分别为0.394、0.360 W/(m·K),顶面导热系数分别为0.305、0.270W/(m·K),其中顶面导热系数小于条面导热系数,表明顶面传热比条面传热的节能效果优越。The paper describes two types of heat flow direction which is numerical calculation for the thermal parameters of KP1 municipal sludge sintered shale porous brick. It uses ANSYS finite element simulation method and composite average Thermal Resistance method. The methods describe the basic principles and specific formulas. And the simulation results were compared. Results show that the wall Coefficient of heat transfer of the side face heat transfer and the end face heat transfer pathway were 1.317 W/（m2·K） and 1.067 W/（m2·K）. They are all less than JGJ 75--2012 specification for the 1.5 W/（m2·K）. They meet about 50% of building energy efficiency requirements. It contrast with the average thermal resistance. They meet the requirements of building energy efficiency. It contrasts with the average thermal resistance calculated of combined material. The thermal coefficient of side face brick are 0.394 W/（m·K） and 0.36 W/ （m · K） , and the thermal coefficient of end face brick are 0.305 W/（m·K） and 0.27 W/（m·K）. Wherein the thermal conductivity of end face is less than the thermal conductivity of side face. It shows that the heat transfer of end face in energy savings is more superior than the heat transfer of side face.
