Abstract: The objective is to obtain fuel having high combustion calorie and superior handleability from a crude glycerin or a fatty acid mixture that have been discarded as industrial waste products. Disclosed is a fuel comprising a water-insolublized fatty acid substance obtained by water-insolubilizing a fatty acid that is contained in a crude glycerin or fatty acid mixtures that are produced as by-products in the process of producing a biofuel from an animal/plant-derived fat/oil. The water-insolublized fatty acid substance is preferably a water-insoluble fatty acid salt, particularly preferably a salt of a fatty acid with a divalent or trivalent metal ion.

Abstract: Provided is a liquid mixing device capable of mixing together two or more kinds of liquids successively in an accurate ratio. The liquid mixing device includes: a first supply system for supplying a first liquid; a second supply system for supplying a second liquid; and a liquid mixing system that receives supply of the first liquid and second liquid from the first supply system and the second supply system, respectively, in which: the first supply system communicates to the liquid mixing system through a first flow rate regulation unit having a first path sectional area; the second supply system is connected to the liquid mixing system through a second flow rate regulation unit having a second path sectional area; and the first liquid in an amount corresponding to the first path sectional area and the second liquid in an amount corresponding to the second path sectional area are allowed to flow into the liquid mixing system, respectively, by making an inside pressure of the liquid mixing system negative.

Abstract: Disclosed is an emulsion-type water-mixed fuel which is free from separating between an oil and a water, thereby being excellent in stability, has a high combustion efficiency, and an extremely high energy-saving effect. An emulsion fuel, in which an average diameter of the water or the combustible oil is 1,000 nm or less (more preferably, average diameter is 200 to 700 nm), is formed by finely-dividing and mixing the water and the combustible oil by a finely-dividing and mixing means, while adding 10.0 to 150.0 parts by volume of the water with respect to 100 parts by volume of the combustible oil (more preferably, 25.0 to 120.0 parts by volume of the water with respect to 100 parts by volume of the combustible oil). Further, the water to be used preferably has a reduction potential of ?100 my or lower, more preferably ?300 my or lower.

Abstract: An atomizer for atomizing a material into fine particles thereof, comprising an atomizing unit and a pump for forcibly supplying the material to the atomizing unit. The atomizing unit comprises: a container having an inner space; an inlet for communicating the inner space of the container to the outside thereof; a honeycomb body being provided in the inner space of the container and having a peripheral surface, a plurality of first holes and a second hole, each of the first holes and the second hole being inwardly bored from the peripheral surface to connect with one another at the inside of the honeycomb body; and an outlet tube being connected to the honeycomb body and extending to the outside of the container for communicating the second hole and the outside of the container. The pump supplies the material into the container through the inlet. A plurality of the atomizing units can be connected in series to use.
