The present invention belongs to a vaporization type liquid fuel burning installation, in particular it is an automatically-pressurized stove using methanol fuel, including liquid storage tank, aqueous methanol fuel, stove body, vaporizing burning system installed in the stove body. automatic pressurization system and electronic igniter, etc.. It adopts the automatic pressurization mode which can preheat a part of liquid fuel to proceed enclosed evaporation in the pressurizing chamber and then introduce the produced vapour into the liquid storage tank, so that the liquid fuel can be automatically pressurized into the vaporizing-burning system so as to implement the fuel full evaporation and complete burning, Said stove is easy to use and safe. Its heat efficiency is high, and its discharge is lower than the standard.
