UDC中华人民共和国国家标准PGB50051—2013烟囱设计规范Codefordesignofchimneys2012-12-25发布2013-05-01实施中华人民共和国住房和城乡建设部中华人民共和国国家质量监督检验检疫总局联合发布中华人民共和国国家标准烟囱设计规范CodefordesignofchimneysGB50051—2013主编部门：中国冶金建设协会批准部门：中华人民共和国住房和城乡建设部施行日期：2013年05月01日中国计划出版社2013北京21前言本规范是根据住房和城乡建设部《关于印发2010年工程建设标准规范制订、修订计划的通知》（建标[2010］43号）的要求，由中冶东方工程技术有限公司会同有关单位共同对原国家标准《烟囱设计规范》GB50051-2002进行全面修订而成。本规范在修订过程中，规范修订组开展了多项专题调研、试验与理论研究，进行了广泛的调查分析，总结了近年来我国烟囱设计的实践经验，与相关的标准规范进行了协调，与国际先进的标准规范进行了比较和借鉴，昀后经审查定稿。本规范共分14章和3个附录，主要内容包括：总则，术语和符号，基本规定…………等。本次修订的主要内容如下：1为满足湿烟气防腐蚀需要，增加了玻璃钢烟囱，规范由原来13章增加到14章。2对钢筋混凝土烟囱修改了有孔洞时的计算公式。原规范计算公式仅限于同一截面的两个孔洞中心线夹角为180度，本次修订对两个孔洞中心线夹角不作限制，方便了工程应用。3为满足烟囱防腐蚀需要，对烟气类别进行了划分，重新定义了烟气腐蚀等级。在大量实践和调研的基础上，针对各种不同类别烟气，对烟囱的选型和防腐蚀处理作出了更加科学的规定。4对钢烟囱的局部稳定计算进行了修订。原规范计算公式不全面，仅考虑了筒壁弹性屈曲影响，本次规范综合考虑了弹性屈曲和弹塑性屈曲影响，参照欧洲标准进行了修订。5对于风荷载局部风压和横风向共振相应进行了修订。增加了局部风压对环形截面产生的风弯矩计算公式；调整了横风向共振计算规定。6将原规范中具有共性内容统一合并到基本规定一章里。7增加了烟囱水平位移限值和烟气排放监测系统设置的规定。8增加了桩基础设计规定。9为适应工程应用需要，并结合工程实践经验，将原规范规定的钢筋混凝土烟囱适用高度由来210m调整到240m。10为满足实际设计需要，在原规范基础上，对钢内筒烟囱和砖内筒烟囱的计算和构造进行更加详细的规定。本规范中以黑体字标志的条文为强制性条文，必须严格执行。本规范由住房和城乡建设部负责管理和对强制性条文的解释，由中冶东方工程技术有限公司负责具体技术内容的解释。本规范在执行过程中如有意见或建议，2请寄送中冶东方工程技术有限公司国家标准《烟囱设计规范》管理组（地址：上海市浦东新区龙东大道3000号张江集电港5号楼301室，邮编：201203），以便今后修订时参考。本规范主编单位、参编单位、参加单位、主要起草人员和主要审查人员名单：主编单位:中冶东方工程技术有限公司参编单位:大连理工大学华东电力设计院西北电力设计院上海富晨化工有限公司冀州市中意复合材料有限公司中冶建筑研究总院有限公司中冶长天国际工程有限责任公司中冶焦耐工程技术有限公司西安建筑科技大学河北衡兴环保设备工程有限公司河北省电力勘测设计研究院苏州云白环境设备制造有限公司北京方圆计量工程技术公司参加单位:重庆大众防腐有限公司上海德昊化工有限公司杭州中昊科技有限公司亚什兰（中国）投资有限公司欧文斯科宁（中国）投资有限公司主要起草人员:牛春良宋玉普蔡洪良解宝安陆士平王立成车轶李国树孙献民王永焕李吉娃龚佳李宁郭亮李晓文郭全国邢克勇姚应军付国勤主要审查人员:陆卯生马人乐张文革陈博张长信于淑琴鞠洪国陈飞刘坐镇3目次1总则·······················································································12术语·····················································································22.1术语···············································································23基本规定················································································113.1设计原则········································································113.2设计规定········································································153.3受热温度允许值·······························································173.4钢筋混凝土烟囱筒壁设计规定·············································183.5烟囱水平位移限值····························································193.6烟气排放检测系统····························································193.7烟囱检测与维护·······························································194材料······················································································224.1砖石··············································································224.2混凝土···········································································234.3钢筋和钢材·····································································254.4材料热工计算指标····························································285荷载与作用·············································································305.1荷载与作用的分类····························································305.2风荷载···········································································305.3平台活荷载与积灰荷载······················································335.4裹冰荷载········································································335.5地震作用········································································335.6温度作用········································································365.7烟气压力计算6砖烟囱···················································································436.1一般规定········································································436.2水平截面计算··································································436.3环向钢箍计算··································································4446.4环向钢筋计算··································································456.5竖向钢筋计算··································································466.6构造规定········································································487单筒式钢筋混凝土烟囱······························································527.1一般规定········································································527.2附加弯矩计算··································································527.3烟囱筒壁极限承载能力状态计算··········································587.4烟囱筒壁正常使用极限状态计算··········································627.5构造规定········································································768套筒式和多管式烟囱·································································798.1一般规定········································································798.2计算规定········································································808.3自立式钢内筒··································································818.4悬挂式钢内筒··································································858.5砖内筒···········································································868.6构造规定········································································879玻璃钢烟囱···················································
