MILESTONE MAPPING

After the feeder supplies the process with iron powder and the dispersion system mixes the solid fuel with air, it is ready to be burnt - this burning iron is what creates the high temperature heat with which we can produce steam. Over the past couple of weeks, we built a testing system to see if the already finished components do what they are supposed to do with EM Group in Geleen. For that setup, the iron powder feeder, dispersion system (which was the topic of the previous milestone), and air fan were used.

We were very excited when we witnessed the first iron flame, yet we immediately saw that the flame pulsated (it was not constant as we wanted). We found out that the air flow of our fan was large, which caused some air being sent to the feeder. We solved it by inserting an extra tube into the dispersion system, and are happy to tell that the system is now able to burn iron properly. A

From the color of the iron oxide we researched, we know what type of iron oxide we are dealing with. This provides us with useful insight about the combustion reaction. What has become a challenge, is the fact that there exists a difference in iron oxide particle size. This will be our main focus for the coming period.

 

Now that the dispersion system is working properly due to our and EM Group's effort, we can focus on automation. We’ve built a control system for a different burner (at EM group) to get acquainted with the process and the problems we might encounter in our own system. This control system will be put to the test in the following weeks.
