4.3 Thermal Cycle 热力循环
4.3.1 The Bidder is requested to describe the Thermal Cycle in his Bid, while equipment outside the T-G Set Package Scope of Supply will be supplied by others. The base cycles shall have uncontrolled extraction points used for feedwater heating. Two or three motor driven feedwater pumps and one standby motor driven feedwater pump are assumed available to the thermal cycle. Other configurations like two steam turbine driven feedwater pumps and one standby motor driven feedwater pump are also acceptable if these are the typical and proven design of the Bidder.
要求投标方对其投标书中的热力循环进行说明，而汽轮发电机组包供货范围以外的设备将由其他人提供。热力循环应有用于给水加热的抽气级。热力循环理论上有两或三台电动给水泵和一台备用电动给水泵。如果是投标方的典型和成熟的设计，也可以采用其他配置，比如两台汽动给水泵和一台备用的电动给水泵。
4.3.2 No air ejectors will be used and the gland steam condenser is located downstream of the condensate pumps.
汽封蒸汽冷却器布置在凝泵下游。系统不采用射汽抽气器。
4.3.3 The thermal kit provided by the Bidder for each Turbine-Generator offered shall include as a minimum the following curves, diagrams, correction factors, calculation formula, etc. The thermal kit provided with the Bid shall contain finalized correction curves which will be reviewed and used to verify the guaranteed output.
投标方为其供货的每台汽轮发电机所提供的热力系统资料中应至少包括以下内容：曲线、图解、修正系数、计算公式等等。与投标书一起提交的热力系统资料中应包含最终修正曲线，该曲线将接受审查并用于核实检验输出功率。
