1管道化间接加热器改造背景中铝河南分公司间接加热连续脱硅工程中,大量应用管道化间接加热器。此加热器因其结构尺寸、换热面积远远超出传统套管式换热器规模,称之为大型套管式换热器。在实际生产中,此换热器两相邻蒸汽进口间的蒸汽管屡屡发生爆裂。为满足设计产品的安全性和实用性,对此处进行改造。 1 pipeline indirect heater retrofit Background China Aluminum Henan Branch indirect heating continuous desiliconization project, a large number of applications of indirect pipeline heaters. This heater because of its structural size, heat transfer area far beyond the traditional size of the bushing heat exchanger, called large-bushing heat exchanger. In actual production, the steam pipe between two adjacent steam inlets of the heat exchanger often burst. In order to meet the safety and practicality of the designed products, we will make some modifications here.
