电厂锅炉毕业设计.pdf

摘 要 本设计是为兖矿集团济三煤矿设计的低热值坑口电站。该项目针对当地情况,选择循 环流化床锅炉,使劣质燃料能被利用,变废为宝,既符合兖矿集团的发展要求,又解决了污 染问题。 整个设计分为初步设计、专题设计两大部分。初步设计部分主要包括文字说明和相关 图纸。本设计说明书由一般部分、专题部分和翻译部分组成。一般部分概述了济三电厂的 初步设计可行性、基本方案，以及主厂房布置情况，拟定了原则性热力系统及主要辅助设 备选型。在专题部分中，主要进行了烟风管道阻力的计算，并对送风机和引风机进行了 型。翻译部分翻译了一篇由中国台湾学者发表的与蒸汽——燃气联合循环电厂相关的文 章。 初步设计图纸为系统及主厂房布置图，主要包括：①热力系统图；②锅炉房底层平面 布置图；③锅炉房运转层及以上平面布置图；④汽机房运转层平面布置图；⑤设备明细表。 关键词:电厂初步设计; 烟风系统; 风机选型 Abstract ThedesignismadeforalowheatvaluepowerplantinYanZhoucoalmanagebureau.This termaimsatthecircumstancesoftheregions,and choosingtheCFB.Sotheinferiorfuelcanbe usedastreasure.Itaccordswiththerequirementofthedevelopmentofthegroup,andalsosolves thepolluteion.
