Technical and economical risk aspects of centrifugal compressor modernization

Abstract

The article describes basic technical, logistic and economic issues occurring during modernization of radial compressors. The basis for the article is the authors' over forty years of experience in the field of compressors, especially process ones. The process of modernization of four radial compressors was described (airborne) working in one of the Polish power plants. These machines were launched after modernization in 2018-2019. Discussed: problems of formulation of modernization parameters, associated risk with 1D and 3D calculation accuracy (CFX code), technological issues, logistic problems and problems acceptance tests.
