Thank you; that's very good information. I like to know the physics and chemistry behind things, particularly stoves, so I really do appreciate your passing that information along.

In addition to a stove not performing properly, I would worry about alcohol having a corrosive effect on the stove. I know here in the US, adding ethanol to automotive gasoline has been controversial in part because the alcohol can cause problems in older cars due to such corrosion. I have talked to at least one person who was using aluminum fuel bottles (of the type intended for gasoline or kerosene) to store alcohol and had his bottle damaged.

I do know some stoves can burn both alkenes (as Primus put it) and alcohol, such as the Optimus 111T, but I hesitate to put alcohol into any stove not specifically designed for it.
