摘要
为解决300 MW级供热机组的凝结水泵配置问题,列举了4种方案,分别为:2×100%容量凝结水泵;3×50%容量凝结水泵;2×100%容量凝结水泵加变频器;3×50%容量凝结水泵加变频器。并从安全可靠性、初投资、运行费用、检修维护等方面对4种方案进行了比较论证,在对各方案进行经济比较时采用了年费用最小法。研究结果表明,2×100%容量凝结水泵加变频器方案的年费用最小,仅为159.4万元/年,且安全可靠,可供同类型机组电站设计参考。
In order to solve the 300 MW level heating unit＇s condenser pump disposition problem,four plans was enumerated,respectively including 2×100% capacity condensate pump;3×50% capacity condensate pump;2×100% capacity condensate pump equipped with the frequency changer;3×50% capacity condenser pump equipped with the frequency changer.And the security reliability,the beginning investment,operating cost,overhaul maintenance and so on,were compared and proved.When carried on the economical comparison in various plans,the expense smallest method was used.The result indicates that the most economic plan is 2×100% capacity condenser pump equipped with the frequency changer one,that the year expense is only 1,594,000 Yuan/year,and it is also safe and reliable,therefore,which is referenced to the same type power plant design.
