Replace the oil in an oil burner with chemical mixtures?


hi there,

i was wondering.. does anyone know which chemicals, when mixed in the proper ratios, will burn both long AND hot, hot enough to melt aluminum in a crucible that sits in an insulated furnace? I have a centrifugal blower (240CFM) that can blow air to the equation if needed to supply some oxygen.

I normally use a mixture of oil/air to melt the aluminum, but since i developed a sudden interest in chemicals, i'd like to try that for a change. Something new.. and interesting.

So any suggestions? :-)

Any hydrocarbons should be the ideal choice when extreme temperatures are not needed, as their decomposition heat values are high. So just stick to oil, other stuff is just more expensive. But if you want to try different stuff, maybe benzene?

EDIT: How about hydrogen or acetylene?

it's not meant as a replacement fuel, so it doesn't matter if it's more expensive. It's just for fun really.. and curiosity. Also i had solids in mind, like aluminum and rust(thermite), but then something that burns less hot and can be made to burn longer.

I saw a thread on things one can do with potassium permanganate, i'll take a look at that, i remember i can get that stuff at ACE hardware. Or is KMnO4 useless for what i'm trying to do?

Maybe some sugar+potassium nitrate? It bruns about 600-1000°C hot.

yes, i found a site that uses sugar and KNO3 to make rocket propellant. I could adjust his formula to try and suit my application. Whether it works or not it'll be fun anyway :-)

A stoichiometric oil flame will easily produce temperatures in excess of 1000C...



One shouldn't accept or resort to the mutilation of science to appease the mentally impaired.

Ofcourse depends on your oil, fat, hydrocarbon etc.
