EXPERIMENTAL STUDY ON VERIFICATION OF RETROFITTING MODIFICATION OF LP FURBINE FLOW PATH[J]. Thermal power generation, 1998, (5): 22-26. DOI: 10.19666/j.rlfd.1998.05.007.
The first modification of 200MW turbine LP part flow path has been successfully conducted on NQ21 unit in Baima Power plant. TPRI carried out the verification tests before and after the modification in accordance with ASME PTC6. The results show that after the modification the specific heat consumption has been reduced and effectiveness of LP furbine arised. Meanwhile the adoption condition of two test methods (ASME PTC6 and ASME PTC 1. 6) has been studied. It is consid- ered that for the first or the second LP turbine modification made by a turbine works it is rational to use the ASME PTC6
and the A SME PTC1. 6 can be used for the modification with proved technologies.
