Moreover, based on the merit and the shortcoming of the fluidized calcinator, it provides a new spiral flow calcinator.

基于流态化煅烧炉的优缺点，还提出了一种新型旋流煅烧炉的设想。

The turbulator can be used to improve the centralization of the casing strings, to allow the fluid to form spiral flow, as well as to improve the displacement efficiency.

使用旋流扶正器既可提高套管的居中度,又可对流体进行导流而形成螺旋流,还可以提高环空水泥浆对泥浆的顶替效率。
