Embodiment 1

[0052] Examples and comparative examples of the invention of the present application are described below.

[0053] First, 8 liters of water (tap water) was heated to 70°C, and the oxidation-reduction potential of the water was reduced to -114mv using a reduction device for bath water manufactured by Environmental Reduction Laboratory Co., Ltd.

[0054] 5.88 liters of A-heavy oil and 160 cc of emulsifier were added to 1.96 liters of the reduced water, and after primary stirring by manual stirring, the mixture was finely divided and mixed by a Nanomizer at a pressure of 3 MP to produce the emulsified fuel of the present invention. Each of the obtained emulsified fuels was a W / O type emulsion, and the average particle diameter of water in the emulsion was 300 to 500 nm.

[0055] The obtained emulsified fuel of the present invention was used as sample 2, and the mixed solution prepared in the same manner as sample 2 was passed through a Nanomizer at a pressure of 8MP to obtain the...

Embodiment 2

[0081] In this example, a diesel generator 13ES type manufactured by Denyo Co., Ltd. was used to continuously measure the concentration of nitrogen oxides and oxygen in the exhaust gas, and to measure the amount of power generated per unit of heavy oil, and to measure the Power generation efficiency of emulsified fuels.

[0082] As the emulsified fuel of the present invention, an emulsified fuel having a composition of 75% by weight of extra heavy oil, 24.7% by weight of water, and 0.3% by weight of an emulsifier was produced and used.

[0083] The emulsified fuel was prepared as follows: 2.50 liters of water and 0.04 liters of emulsifier were added to 8.33 liters of A-heavy oil (100 parts by volume of heavy oil: 29.7 parts by volume of water: 0.5 parts by volume of emulsifier), after primary stirring by manual stirring, at 3MP Micronization and mixing by Nanomizer unit under pressure. The average particle diameter of water in this emulsion fuel is about 300-500 nm.

Abstract

Disclosed is an emulsion-type water-mixed fuel which causes no separation between an oil phase and an aqueous phase and therefore has excellent stability, has a high combustion efficiency, and an extremely high energy-saving effect. Specifically disclosed is an emulsion fuel in which an aqueous phase or an oil phase has an average particle diameter of 1000 nm or less (more preferably 200 to 700 nm), which can be produced by finely dividing and mixing 100 parts by volume of a combustible oil with 10.0 to 150.0 parts by volume (more preferably 25.0 to 120.0 parts by volume) of a water by a finely-dividing / mixing means while adding the water tothe combustible oil. The water preferably has a reduction potential of -100 mv or lower, preferably -300 mv or lower.

Description

technical field [0001] The present invention relates to a water-oil system emulsified fuel, and in particular to forming the constituent particles of an emulsion of water and combustible oil into a state of ultrafine particles, and using the obtained emulsified fuel as a fuel for various power engines or combustion furnaces When, can contribute to the invention of energy saving, pollution prevention. Background technique [0002] Recently, with the high price of crude oil and the entry into force of the Kyoto Protocol, reducing oil consumption has become a major international issue. Under such circumstances, Japan has also carried out research on emulsified water-added fuels, and proposed many patent applications on their composition and manufacturing methods, and some of them have been put into practical use.
