摘　　要：有机热载体炉作为供热系统中重要的设备之一,其管口与外部热媒管道连接处由于热位移而产生相互作用力,为了确保锅炉的安全运行,外部热媒管道对有机热载体炉的作用力不能超过其管口最大应力允许值。根据多年来工程项目的实践,采用CAESARⅡ应力分析软件,通过对有机热载体炉准确建模,使有机热载体炉与外部热媒管道连成互相作用的整体,不但能校核各个工况下连接管的受力情况,而且更加准确地计算分析有机热载体炉管口的应力大小。As one of the most important equipment of the heating system,nozzles and external piping of organic heat-transfer boiler will have thermal displacement force in each other.In order to ensure the boiler safety running,such force shall not exceed the allowable value of the boiler.Based on project practice for many years,and using the CAESARⅡstress analysis software,accurately modeling of organic heat-transfer boiler in a example to interact with external piping as a complied system,can not only check stress analysis of the external piping system,and more accurately calculate and analysis of the stress for nozzles of organic heat-transfer boiler.
