火焰直接加热的热载体炉炉内传热计算及最高膜温的确定

Heat Transfer Calculation of Fire Heater and Analysis of Maximum Film Temperature

在石油化工、纺织、印染等轻工行业,为使介质均匀缓和加热,且需要严格控制介质出口温度时,常采用中间热载体传递热量。中间热载体在火焰直接加热的热载体炉中升温加热。介绍了热载体炉的常用型式及炉内的传热计算,并针对运行中关心的有机热载体变质的问题,介绍了热载体炉中最高膜温的计算。

In the fields of petroleum chemical,textile,printing and dyeing and other light industries,the medium. heat carrier is often used to fransfer heat in order to moderate the heating of the medium and to strictly control the outlet temperature of the medium Medium hot oil is heated in heat carrying agent furnace. Heat transfer calculation is mentioned about heat carrying agent furnace and max. Film temperature calculation is also demonstrated in order to explain deterioration of organic heat carrying agent.
