1. Instruction Model: N600-16.67/537/537 Type: sub-critical, tandem-compound, combined HP&IP, 2 LP double-

flow, intermediate reheat, condensing turbine Product code NO.: H158

1.1. Main Specification Calculated load 600MW Main steam pressure 16.67MPa(a) Main steam temperature 537

Reheat steam temperature 537 Working speed 3000r/min Rotating direction (seen on control valve end) CW Designed cooling water temperature at rated condition 33 Rated back-pressure 10.13 kPa(a) (76mmHg) High back-pressure 11.86 kPa(a) (89mmHg) Feed water temperature at rated condition 277.2 Regeneration system 3HP HTRS+DRT +3LP HTRS Type of BFP to be driven BFP Turbine Main steam flow at rated condition 1887.028 t/h Heat rate at rated condition 8183 kJ/(kW.h) 1954.5 kcal/(kW.h) Last blade height 710mm

1.2. Main Operating Condition 1.2.1 The turbine will produce 600MW at the generator terminals while operating

at rated inlet condition, rated back-pressure, the generator efficiency is 98.8%, 0% make up and all heaters in service. This operating condition is called 100% TMCR condition (Heat Rate Guarantee).

1.2.2 The turbine will produce 600MW at the generator terminals while operating at rated inlet condition, rated back-pressure, the generator efficiency is 98.8%, 3% make up and all heaters in service. This operating condition is called 100% TMCR condition (Output Guarantee).

1.2.3 The turbine will produce 631MW at the generator terminals while operating at rated inlet condition, rated back-pressure, 0% make up and all heaters in service, with valves wide opening and the main steam flow 2009.998t/h. This operating condition is called VWO condition.

1.2.4 The turbine output is still 600MW with all of the HP feed water heaters out of service.

1.3. Data Used in The Thermal Performance Calculation 1.3.1. Design pressure loss

Item value Main stop valve &`control valve and pipe 2.5% Intermediate pressure combined valve and inlet pipes 2.5% Reheater and inlet/outlet pipes 10% Connecting pipe of IP&LP 2% Extraction pipe of HTR6, HTR7 3% Extraction pipe of HTR1 to HTR5 5% Extraction pipe of BFPT 3%

1.3.2. Heater terminal differences are as follows:

HTR1 HTR2 HTR3 HTR4 HTR5 HTR6 HTR7Heater terminal difference 2.8 2.8 2.4 0 0 -1.6 Drain terminal difference 5.6 5.6 5.6 5.6 5.6 5.6 1.3.3. The generator efficiency is 98.8% at 100% TMCR condition. 1.3.4. The boiler feedwater pump efficiency is 83%, and the boiler feedwater

pump turbine effciency is 81%. 1.3.5. All the pressure listed in this document are absolute value.
