(CN1408992-A)   NOVELTY - Converting water into fuel comprises mixing water with ethanol in a certain ratio by weight; heating and evaporating the obtained mixture to obtain a vapor mixture; and passing the vapor mixture through a direct current (DC) electric field.    USE - For converting water into fuel for use as secondary fuel for engines using gasoline, diesel oil or gas as fuel.    ADVANTAGE - The invention converts water into fuel which is employed as an auxiliary fuel of the oil and gas used in the existing power equipment to save the energy sources, reduce the consumption of the oil and gas and alleviate the environmental pollution. The apparatus of the invention can be operated safely and maintained conveniently and easily.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a fuel-converting apparatus comprising an evaporating system and a DC electric field system, wherein the evaporating system consists of a tank (8) and an evaporator (11), and the DC electric field system consists of a riser pipe (1), a negative electrode (2) fixed in the riser pipe and a positive electrode (3) fixed outside of the riser pipe. In the evaporating system, a flow control valve (9) is provided between the tank and the evaporator. The evaporator is of an indirect heating type in which a heating pipe (14) heats the mixture of water and ethanol indirectly in the evaporator to obtain the mixed vapor. The vapor produced by the evaporator is transferred into a vapor reserving pipe (13) through a connecting pipe (12) connected with the evaporator. The vapor reserving pipe is connected with an outer casing (15) of the positive electrode of the DC electric field system and the riser pipe. In the DC electric field system, the riser pipe is made of an insulating material. The negative electrode is fixed inside the riser pipe and the positive electrode corresponding to the negative electrode is fixed outside. The outer casing is equipped around the positive electrode. An outlet hole for the combustible gas is formed at the top of the riser pipe and connected with a fuel gas pipe which is connected with a fuel gas collecting pipe. An exhausting vent is formed at the top of the outer casing of the positive electrode and is connected with an exhaust gas pipe (6) which is connected with an exhaust gas collecting pipe (7).
