What made me interested is I produce lots of aluminum chips from my Machine shop. I save them up until I get enough to take them to a scrap yard. The time and gas it takes to do this is almost a waste of time. This got me wondering if it was feasible to burn it somehow and get more from it than junk yard prices.
When I searched on Google I was surprised to see the article involving empty cans.
I thought it always melted, We'd despose of our cans in this fashion in the woods. The fires we had were so hot a can would last about 1 second. Some of those places we went to a lot and it would require cleaning the fireplace out occasionally. You'd always find big globs of aluminum. Maybe that was just cans that were in fires that weren't so hot.
I've thrown many a hard drive into the wood stove and made large globs of aluminum. Once a fire is established with wood, drywall burns kind of like coal in the stove. I burned several rooms worth, rather than throw it in the woods.
A common flash powder like used in M-80s and other fireworks is made of aluminum powder and an oxidizer. So yes, aluminum burns but I have to see this thing work to believe it. Coal has a long established history for home heating.
