摘　　要：以太原第一热电厂 1 1号炉为对象 ,分析对流受热面积灰对一级过热器的影响以及对过热蒸汽吸热量和再热蒸汽吸热量分配比例的影响 ,提出了以受热面吸热量比例作为灰污特征参数或辅助特征参数 。Taking the boiler No. 11 in Taiyan No. 1 Thermal Power Plant as an object, the influence of ash deposition on convective heating surface upon the first superheater, as well as up on the distribution ratio between heat absorption capacity of the superheated steam and that of the reheated steam has been analysed. Taking the distribution ratio of heat absoption capacity concerning different heating surfaces as fouling characteristic parameter or auxiliary one, a basis has been provided for further improving the ash deposition monito ring model.
