Abstract:

The dynamic pilot test of coke oven battery shows that with adoption of salt bath coil structure,the inner wall surface temperature of  heat absorber on the ascension pipe of coke oven battery can be controlled,and the tar vapor contained in the raw gas will not condense.During the whole coking period,the inner wall surface temperature of heat absorber,total heat exchange coefficient and the radiation heat exchange coefficient of the coking chamber are stable at the early stage,and decrease at the late stage.The radiation heat exchange coefficient of raw gas and the radiation heat exchange coefficient of the coking chamber decrease as the height increases.
