An analysis on off–design performances of fully–fired gas turbine / boiler cogeneration is presented. The complication can be eliminated by using non–dimensional parameters and dimensional analysis in off–design investigation. The suitable dimensionless parameters on boiler side have been derived, which can be easily applied to the correction of cogeneration test on site at the first stage of plant commissioning process if the parameter variations with ambient condition are not supplied by manufacturer. According to the method developed, the off–design performances of a demonstration fully–fired combined cycle cogeneration in China have been analyzed. Two operating choices are investigated thoroughly. From the results obtained, some considerations of part–load performances of such type power system are given.
