| Abstract: | Directing against problems encountered in the process of cold-state start-up of boiler and medium speed warm-up of the steam turbine for the first 300 MW CFB unit manufactured in China,such as the temperature of main reheated steam is unable to be risen,the main steam pressure being abnormally enhanced,superheat degree being lowered,and the effectiveness of steam turbine warm-up being unable to be ensured etc.,analysis has been carried out from two aspects,i.e.operation adjustment in initial period of boile... |
