NOVELTY - Method of enhancing flammability performance of flammable liquid, comprises: inputting various flammable liquid including e.g. alcohol, kerosene and light oil into treatment apparatus (3) and forcibly contacting with a lump of dolomite or a lump of limestone; transferring the vaporized substance to condenser (2), to produce a flammable liquid fuel (4); and storing the liquid fuel in the storing container and transferring to heating container (5) heated at 40-350 degrees C by means of a thermal medium oil heating apparatus.    USE - The method is useful for enhancing flammability performance of flammable liquid.    ADVANTAGE - The method: maximizes energy efficiency and energy saving effect; prevents environment pollution; and is cost effective.    DETAILED DESCRIPTION - Method of enhancing flammability performance of flammable liquid, comprises: inputting various flammable liquid including alcohol, kerosene, light oil, gasoline, edible oil, waste oil or mixed oil into a treatment apparatus (3) and forcibly contacting with a lump of dolomite or a lump of limestone at 50-350 degrees C to vaporize the same; transferring the vaporized substance to a condenser (2) and condensing in it, to produce a flammable liquid fuel, and storing the liquid fuel in a storing container (4) formed in a lower side of the condenser; and storing the liquid fuel in the storing container and transferring to a heating container (5) heated at 40-350 degrees C by using a thermal medium oil heating apparatus and heating at 40-350 degrees C. INDEPENDENT CLAIMS are included for:    (1) a method for enhancing flammability performance of flammable liquid, where the flammable liquid produced by heating and reacting a lump of limestone or a lump of dolomite is mixed with anthracite powder or mixed with sulfur powder, and a solid fuel is prepared with the help of a means for mixing the above compounds and is inputted into a combustion chamber having a thermal medium oil heating apparatus and is heated at 40-350 degrees C, so that a vaporization operation and flammability performance are enhanced, and a perfect combustion is obtained to maximize an energy efficiency, and an energy saving function is obtained;    (2) a method for enhancing flammability performance of flammable liquid, comprising inputting a flammable liquid directly into a thermal medium oil heating apparatus and selectively heating at 40-350 degrees C, thus enhancing vaporization and flammability performance and an energy efficiency; and    (3) an apparatus for enhancing flammability performance of flammable liquid, comprising an electrical heater (H), installed by providing a thermal medium oil (300) between the walls formed of an inner wall and an outer wall of a treatment chamber; a management apparatus (H1) that manages the electrical heater by using a computer method; an outer lid opened and closed by using a cylinder engaged in an inlet port; a screw provided in a transportation pipe communicating with the outer lid; a standby part opened and closed by using an opening and closing door formed in an inner side of the transportation pipe; an inner side opening and closing door disposed in a lower side; an agitating chamber having a screw driven by using a hydraulic motor (M) provided in a bottom of the treatment chamber; a sealing door provided in an outlet port; an engaging bolt nut and engaged; a filtering net provided in an inlet portion of one side of a ceiling of the treatment chamber; a discharge pipe having an opening and closing valve installed; a treatment apparatus of which one end is connected with a condenser formed of a pressure meter and a thermometer; and flammable liquid inputted in the interior of the treatment chamber by less than half; a treatment agent A such as a lump of limestone of a diameter of 10-30 cm or a lump of dolomite of a diameter of 10-35 cm inputted by 5-50 wt.% with respect to the total amount of flammable liquid and sealed and heated at 50-350 degrees C such that a flammable liquid is vaporized, the discharge port is opened, the vaporizing substance is transferred to the condenser and the liquidified liquid fuel is stored in the storing container; a thermal medium oil stored in the wall; a heating apparatus formed of a heat detector and an automatic switch; and the fuel stored in the heating container which is able to keep the inner temperature at 40-350 degrees C.
