1·Electric heat tracing and steam jacket heat tracing in sulfur recovery unit have been compared in the light of economy and unit features.

从经济及装置特点两方面对硫磺回收装置电伴热和蒸汽夹套伴热进行了比较。

2·However, it is reasonable to adopt steam jacket heat tracing for sulfur recovery unit, as the steam produced by the unit itself has no other utilization.

对硫磺回收这类有自产蒸汽且蒸汽又难有别的利用途径的装置，采用蒸汽夹套伴热是合理的。

3·Jacket can access certain temperature steam or liquid, high melting point to prevent the crystallization of liquid generated.

夹套中可通入蒸汽或一定温度的液体，防止高融点液体产生结晶。

4·And it can transit heat and save the energy in the utmost according to steam flowing principle with the applying of miller jacket technology.

采用高效米勒板夹套换热技术，应用科学的蒸汽湍流原理实现了大限度的热传导、节能效果；

5·Conveying crystallizable materials, in the front cover and pump body can be designed with heat preservation jacket, work through steam heat melt.

输送易结晶物料时，在前盖和泵体上可设计带有保温夹套，工作时通过蒸汽保温融化。
