| Abstract: | Analytical off-design performances of combined cyclewith single shaft gas turbine are derived with typical analyticalcomponent performances. These performances presentedby relative form are not accurate for any specific set but typicaland accurate enough for common sets. The relation between efficiencyand power output of combined cycle can be approximately expressed asa single curve for different gas turbine design parameters.It is pointed out that the operation mode of steamside is important in the off-design condition. The comparison betweensliding pressure mode and throttle mode is given and discussed. In lowload, the approach temperature difference decreases quickly, and an operationmethod is proposed to prevent negative approachtemperature difference. |
