COMBINED CYCLE PLANT RECONSTRUCTION METHOD, DISTRIBUTION DUCT, AND COMBINED CYCLE PLANT

摘要

PROBLEM TO BE SOLVED: To provide a combined cycle plant reconstruction method and the like capable of restricting an increasing in cost while applying existing facility and improving CC efficiency.;SOLUTION: This invention comprises the steps for removing two gas turbines 10 and two ducts 17 [S12]; setting a new gas turbine 10a showing a higher efficiency than that of the two gas turbines 10 and becoming a less number of the two gas turbines 10 in place of the two gas turbines 10 [S13]: and installing a distribution duct 70 for guiding exhaust gas from a new gas turbine 10a to distribute it to two exhaust gas recovering boilers 20 in place of several ducts 17.;SELECTED DRAWING: Figure 5;COPYRIGHT: (C)2017,JPO&INPIT
