600MW火电机组节能优化降耗分析研究 电力学专业VIP免费

摘要全球工业的持续进步依赖充足的能源，因此此类资源的富裕度就是评估目前国家工业发展情况的关键指标。电力、航空、航海、石油是人民生活所需要的必备条件，这些都依赖于能源的消耗，全球盲目的开发和勘探能源，使能源自身的格局平衡受到强烈的冲击和破坏，为此人类在关注着能源的有效利用率，节能降耗已成为人们所关心的问题。在上述环境中，火力发电公司为了符合国家以及社会进步需求，持续探究全新的节约损耗的方式。600MW火电机组是目前我国电力企业的重要设备，其节能的成效直接关系着企业与社会的效益，因此，本文探讨600MW火电机组能耗与节能措施具有一定的现实意义。关键词：600MW火电机组、节能优化、降耗AbstractTherapiddevelopmentoftheworldindustrydependsonthesupplyofenergy,sothedegreeofenergyisanimportantindicatorofacountry'sindustrialprogress.Electricpower,aviation,marine,oilisanecessaryconditionforthelivelihoodofthepeople,thesearedependentonenergyconsumption,globalblinddevelopmentandexplorationofenergy,theenergybalancepatternitselfhasastrongimpactanddestruction,thereforehumanwatchingeffectivelyenergyutilization,energysavinghasbecomethepeopleconcernedtheproblem.Inthiscontext,inordertoadapttotheneedsofthetimesandsocialdevelopment,thethermalpowerenterprisescontinuetoexploremeasurestosaveenergyandreduceconsumption.600MWthermalpowerunitisanimportantequipmentintheelectricpowerenterpriseofChinaatpresent,theenergysavingeffectisdirectlyrelatedtotheenterpriseandsocialbenefit,therefore,thispaperhascertainpracticalsignificancetoexploretheenergyconsumptionof600MWthermalpowerunitsandenergysavingmeasures.Keywords:600MWthermalpowerunit,energysavingoptimization目录1引言................................................................31.1课题的背景及意义..................................................41.1.1国内外发展现状..................................................42锅炉燃烧及制粉系统的优化............................................52.1锅炉主要热损失....................................................52.2影响锅炉燃烧效率的因素及优化......................................62.2.2空气预热器漏风率................................................82.2.3炉膛出口过量空气系数............................................82.2.4灰渣可燃物含量..................................................92.3.1中速磨直吹式制粉系统...........................................102.3.2中间储仓式钢球磨制粉系统.......................................112.3.3改进制粉系统的建议.............................................123汽轮机及热力系统...................................................133.1汽轮机主要损失...................................................133.2影响汽轮机效率的因素及优化.......................................163.2.1主蒸汽参数.....................................................161、主蒸汽温度的影响..............................................162、主蒸汽压力....................................................173.2.2冷端参数.......................................................173.2.3给水温度.......................................................183.2.4控制加热器端差.................................................183.2.5对减温水的控制.................................................194主要辅机系统优化...................................................204.1风机的一些节能措施...............................................204.1.1选择与锅炉风(烟)系统相匹配的风机...........................204.1.2采用先进的调节方式...............................
