文档介绍

文档介绍:江苏大学工程硕士毕业论文摘要“熟电联产、集中供热”是利国、利民、利社会的大好事,它的优点是:节约能源、保护环境。根据镇江市城市集中供热规划,大港热电厂负责对镇江新区化工片区实行集中供热。本规划就是根据大港热电厂的装机容量、化工片区内的热负荷状况结合化工片区整体规划对该区供热方式、供热管网的布置做了近期(2006~2007)和远期(2008~2010) 规划。根据《关于发展热电联产的规定》,小于50MW的热电机组热电比必须大于1,供壹!}i管网的总长度一般不能大于4公里。本规划热源选用了热电比为400%,总热效率为57%的15MW抽凝机组。对供热管网在大于4公里的情况下经过了准确的水力计算进行了科技创新,确保用汽点使用的蒸汽温度、压力满足用户要求,。本规划主要包括以下几个方面的规划:热用户调查及热负荷计算、热源规划及热电联产的方式、供热管网规划、环境评述,最后汇总出以上规划的结论和建议。关键词:供热规划、热负荷、集中供热率、供热管网、热电比江苏大学工程硕士毕业论文‘‘Combinedgeneration of heat and electricity and centralized heat supply”is apolicy which is not only beneficial tothesociety but tothe people inenergy-saving and environment protection are tothecentralizedheatsupply plan med by the anization,Zhenjiang Dagang Thermal Power Plantisresponsible forthe centralized heat supply inZhenjiang the Chemical Engineering Region inZhenjiang Development short—term(2006—2007)and long-term(2008-2010)plans aremade based on thegenerators’capacity of Dagang Thermal Power Plant,the heat load in theChemical Engineering Region inZhenjiang Development Area,the way heatistobesupplied and sto belaid outintheChemical Engineering Region inZhenjiang Development Area.
