摘要

从给水含氧量的适应性、系统配置的繁简程度、系统运行的经济性和安全性

对配置西门子、GE和三菱公司9F等级燃气-蒸汽机组(燃机)的余热锅炉典型给水系统进行了对比分析。结果表明:在机岛侧尽量采用除氧式凝汽器或者配置了旁路除氧系统的凝汽器

以确保在任何工况下

余热锅炉的给水含氧量均可达标;优选出更适合机组纯凝运行时余热锅炉的给水系统

结合供热机组对余热锅炉给水系统的特殊需求

提出了适用给水含氧量更高、更节能运行的余热锅炉给水系统。

Abstract

On the basis of the typical feed water systems in heat recovery steam generators(HRSG)on 9F class gas-turbine combined units manufactured by SMS

GE and MHI GT

relative comparisons were carried out

from such aspects as feed water oxygen content adaptability

system complexity degree

system operation safety and economy.It suggests that the deaerating condenser or condenser equipped with bypass deaerating system should be adopted at the unit side

to ensure the oxygen content in HRSG feedwater satisfy the requirements under any conditions.A feed water system that is more suitable for unit under full condensing condition was selected.Furthermore

combined with the special requirements of heating supply unit on feed water system

the current feed water systems of heat supply units were analyzed and the optimized feed water system was proposed.
