55°F (13°C)
Denatured alcohol is a low flashpoint (temperature at which vapored chemicals will ignite) of only 12 degrees C. Gasoline has a flashpoint of -40 degrees C. Though it has a higher flashpoint than gasoline, it burns while the gasoline is burning and burns a bit longer when mixed. Denatured alcohol, also known as methylated spirits, is ethanol with additives to make it poisonous or unpalatable and sometimes dyed to give it color. Since most parts of the world heavily tax and control alcohol meant for consumption, these additives get around those issues. Posted. You cannot simply tell the flame temperature of any burning chemical. If you simply light some liquid, or when it is sprayed out into the air from a burner, there can be quite different temperatures. A nice example is the gas stove. The blue flames have a totally different temperature than the orange flames. So, it depends on how it is burnt. Methyl alcohol vaporizes and burns at a lower temperature than ethyl alcohol. However, it is also satisfactory for use in Aster locomotives. The key point is to use a fuel which is free of water. Ethyl or methyl alcohol purchased in paint or hardware stores may contain up to 9% water. The surface temperature of burning alcohol is around the 500 Fahrenheit mark (260 celsius). Also, since the tip of the flame burns white and has the capacity to heat glass rods sufficient to bend them, the max heat would (I think!) be in the region of 1100 celsius. The flash point for denatured alcohol is 55°F (13°C) [10] . This means that ethyl alcohol not intended for drinking can have its vapor produce a visible flame, in the presence of an ignition source and oxygen, at a considerably lower temperature than ethyl alcohol intended for drinking. Based on the volume increase, due to the expansion of the denatured alcohol vapor around the Victim’s Volkswagen convertible, the concentration of denatured alcohol vapor in air decreased to less than 3.3% and the temperature decreased to less than 55ºF (13ºC). As a result, the visible flame went out.
