摘要：

On the tail-heating surface of coal fired boilers, the highest temperature of ash deposit could reach 600-700degreesC. If the radiative heat transfer is neglected as usual for the convenience of simplicity, it would induce certain model error at the deposit temperature mentioned above. Based on our former work, this paper proposes a model to determine the fouling thermal conductivity of ash layer including the radiative heat transfer, and the numerical results are given too.
