Is induction effective for heating flowing iron powder particles?

It’s an aerosol with particles carried by air in a pipe at a consistent rate.

It’s an aerosol with particles carried by air in a pipe at a consistent rate. The rise in temperature is the issue in that case because the source of the equation here has skewed the metal particles, even though it will heat a little with induction. If you're looking for high temperatures on those metal particles, the air outside those or around those metal particles is such a big heat sink that you don't see any temperature in the air, so as a rule, metal particles flowing in an airstream do not heat very effectively or effectively enough to cause a high temperature.
