    Can anyone tell me what is the lowest temperature fire can burn at?

    Also can anyone tell me what is average temperature of an open air hydrocarbon fire and the average temperature of a fire in say building floor thats on fire?

    From what I recall some solvents burn at very low temps. Maybe as low as 50-60c. As for a hydrocarbon fire it would depend on the material but you would be in the range typically of about 500-800c as for house fires, quite often they can reach very high temps due to the heat being confined etc. I've talked with firemen who informed about flashovers (where the smoke itself ignites). Apparently they can reach thousands of degrees. But don't quote me on this

    It depends on the medium for the fire. For example, in a liquid the lowest temp. at which a fire can burn varies greatly, because it depends on the ignition temperature (i.e. the lowest temp. = the flashpoint). Pure alcohol burns at between 60 - 70 Fahrenheit.

    Not sure about the second question.
