'Merchant Plant' Capital Cost Trades That Can Reduce the Initial Capital Investment Needed for APFBC Repowering

摘要

Earlier evaluations provided concept evaluation estimates of the performance and cost for repowering two power stations with advanced circulating pressurized fluidized bed combustion combined cycles (APFBC). Each APFBC reowering evaluation used a Foster Wheeler APFBC island supplying a single APFBC-modified Siemens Westinghouse Power Corporation W501F gas turbine, retaining the use of the existing station's steam turbine/generator. The existing units evaluated from these stations were the following: centre dot The Carolina Power & Light Company's L.V. Sutton station. Two APFBC repowering configurations were assessed: repowering 106 MWe reheat Unit 2 with APFBC; and, repowering both Unit 2 as well as the 97 MWe non-reheat Unit 1 with APFBC. centr4e dot The Duke Energy Dan River station: repowering the 150 MWe reheat Unit 3 with APFBC.
