| Abstract: | There are two methods for correting calculating for steam turbine performance test,one method is by heat balance calculating,the other method is by using the correting curves.By analysing the papers on this subject,the high precision equivalent enthalpy drop method correcting model is choosed and the models for heaters calculation are improved,the correcting calculating method is provided.As an example,the corrrecting curves calculating process and results for a supercritical N600-24.2/566/566 unit and the ... |
