We are looking to add one GT/HRSG package in our existing 150MW supplementary fired CC plant in order to stop duct firing and use the 3rd GT/HRSG to supply about 160-170 kpph (~75ton/hr) HP steam presently coming by Duct firing. Maximum Steam pressure for ST is @ 1470psi (100bar) & steam inlet temperature is 930F (500C). Since we are limited by our Electrical Power Evacuation limit, therefore only 50-55MW GT model will be compatible. Exhaust Temp. of new GT shall be > 970F and HRSG shall be Single Pressure (HP drum only) because LP steam is already on maximum limits. I am asking for the best GT model suitable for integration which provides the best efficiency at minimum cost. In my view Siemens SGT800 or GE 6F.01 are the only proper candidates. I would appreciate any detailed views from engineering community. Also what will be approximate cost of of this addition. it may be noted that ST, Condenser & Cooling Tower are not needed because overall steam requirements will not change.
