A Novel Structure In Designing CHP Plant Via Feedwater Heating Repowering

In ordinary, repowering is converting old steam power plants in to combined cycle plants. In this paper, considering the distinguished characteristics of feedwater heating option for new power plants, study their application requirements on Steam power plants. After determining characteristics of more suitable power plants for repowering using this procedure, introduce common methods of feedwater heating option and explain the characteristics of each manner for using in steam power plants. In the second step, considering expected conditions, compare suitable cases for repowering. This paper offers main points in different types of feedwater heating option and their specifications.
