Stagnation jet mixer

As mentioned above, the Koppers-Totzek gasifier of powdery coal [4, 5], the Stagnation jet mixer [14] and the Trost jet mill [20] are practical examples of the successful application of impinging streams. Apart from these, very few industrial applications of impinging streams had been by the end of the last century, [9, 21], The following may account for the fact that the application of impinging streams has progressed so slowly ... 

The comparative results indicated by the data given in Fig. 10.3 are completely opposite to those of Brauer [14] who reported much shorter mixing times in the stagnation jet mixer than in STR. Although the stagnation jet mixer lacks some of the key elements needed for the reactor, it has a flow configuration very similar to that of the SCISR. This phenomenon is unexpected, but the multiply repeated experiments verify that the data are true.
