There were reports of using small iron pellets as a fuel, so does it mean rust creation can be considered combustion as well?

- marcosdumay 6y agoIs it hot, relatively fast, and self sustaining? If you make your pellets small enough, it is. The combustion of steel brushes is quite interesting to watch. If you make your pellets too small, then is stops being an ordinary combustion and becomes an explosion.

- scsilver 6y agoIf you get small enough, you start getting into the territory of dust explosions. https://en.m.wikipedia.org/wiki/Dust_explosion https://en.m.wikipedia.org/wiki/Dust_explosion Another interesting phenomenon is spontaneous combustion where exothermic reactions get hot enough to start the combustion process in a medium. https://en.m.wikipedia.org/wiki/Spontaneous_combustion#:~:text=Spontaneous%20combustion%20or%20spontaneous%20ignition,temperatures)%20and%20finally%2C%20autoignition https://en.m.wikipedia.org/wiki/Spontaneous_combustion#:~:te.... I was a fire engineer in a past life, forgot the science but remember the cool phenomenons.

- kortex 6y agoRight. If you increase the surface area or add more oxidizer, iron quite readily burns, see thermic lances, ferrocerium, metal powder explosions etc. But that is different than rusting.
- mikewarot 6y agoA cutting torch for steel is really just an oxy-acetylene torch. Once the flame gets the steel hot enough, you cut back the acetylene, and the pure oxygen burns the steel away. It's a surprisingly effect method of cutting.
