摘要
结合同类煤电机组余热利用长距离大温差供热项目经验,从基本原理开始阐述,介绍了AFT Impulse软件在工程实例中的应用,逐步说明有压管道水力瞬态分析,并结合工程案例,分析出非恒定流体向恒定流体变化过程中产生的水击波对供热系统的危害,结合数学模型分析提出的心得及建议,以便将水力瞬态分析的成果在供热系统中更好地推广和应用,有效地指导设计与工程建设.
Abstract
Combined with the experience of projects similar to waste heat for long-distance and large temperature difference heating by coal-fired power units,this paper starts from the basic principles,introduces the application of AFT Impulse software in engineering examples,and gradually explains the hydraulic transient analysis of pressure pipelines.Combined with engineering cases,it analyzes the harm of water hammer waves generated in the process of changing unsteady fluid to constant flow to heating system,and puts forward corresponding suggestions based on mathematical model analysis,In order to better promote and apply the results of hydraulic transient analysis in the heating system,effectively guide the design and engineering construction.
