燃气—蒸汽联合循环电厂水工系统布置优化探讨

Discussion on Layout Optimization of Hydraulic System in Gas-steam Combined Cycle Power Plant

燃气—蒸汽联合循环电厂与传统燃煤电厂相比具有占地少、建设周期短、清洁无污染等突出优势,近年来在发展较快、电能短缺的长三角及珠三角地区各大城市得到了大规模的建设。这些地区土地资源紧张,电厂占地面积受限,对机组布置及设计优化要求较高。依托深圳某电厂扩建工程实例,就电厂水工专业设计方面的冷却水系统、工业水系统、消防系统及雨水回收系统的布置优化提出了几种可行方案,可为后续燃气—蒸汽联合循环电厂工程的紧凑布置设计提供借鉴。

Compared with coal-fired power plant,gas-steam combined cycle power plant has several advantages such as smaller land occupation,shorter construction period and no pollution.A bunch of combined cycle power plant are constructed at some high speed developing cities at Yangtze River Delta and Pearl River Delta during these years.Limited land resource in these cities raises high requirement of plant layout and design optimization.This article introduces several practical plans for layout optimization in cooling water system,service water system,fire fighting system and rain ater recycle system basing on a Shenzhen power plant project,which may be useful for further gas-steam combined cycle power plant design.
