1、XX有限公司6t/h燃煤蒸汽锅炉房工艺设计摘要本设计是对一家假想公司6t/h燃煤蒸汽锅炉房的工艺设计,该公司提供一块60000×20000mm的空地来作为锅炉房的地基基础。在文中通过公司给出的数据和对锅炉房设计所需数据的计算,给出了该锅炉房合理的设备选型依据和主要设备的型号,如:锅炉型号、水处理的选择、鼓风机、引风机的选择等。经计算最终决定采用1台SZL6-1.25-WII型蒸汽锅炉,额定工作压力1.25MPa。由于本锅炉房原水为城市自来水,其硬度和含氧量不符合锅炉给水要求,所以对原水需要进行软化和除氧处理。软化系统选用两台逆流再生钠
2、离子交换器,轮流运行使用。流动床的优点为出水质量高,能连续工作,操作较方便,需要的交换剂量较少。除氧方式为了方便,选用化学除氧中的亚硫酸钠除氧法。对于鼓风机与引风机,根据计算出的烟气量与送风量,分别选取了型号为GG6-15No.6.9D的鼓风机与型号为GY6-15No.10.5D的引风机。在确定了该锅炉房各项设备的型号后,根据GB50041-2008《锅炉房设计规范》和相关技术措施的具体要求,确定了不同规模情况下锅炉房的配置方案,从而确定了锅炉房各个设备的放置位置与汽水管道、烟风管道的平面布置。关键词:工业锅炉房,锅炉,设计IThed
