JPS61173015A - Method of burning fatty lower alcohol and burner thereof - Google Patents

Abstract

PURPOSE:To burn fuel steadily with stabilized flames in a desired size of flame pattern and under the desired condition of combustion without using any wick, by charging fuel of which main constituent is fatty lower alcohol in a container provided with a metallic heat conductive body, and by heating and evaporating fuel by transmitting combustion heat to fuel the intermediary of a heat conductive body after ignition. CONSTITUTION:A container 2 is vertically held in position and the top end of a fuel 1 is ignited by a match or the like. The combustion heat is transmitted to a radiant 5 from the heat receptor 4 of a heat conductive body 3 projected in a combustion flame 6, heating the fuel 1. The fuel is heated up to its boiling point, vaporized and evaporated, mixed with air in the opening of a container 2, ignited and burned. That is, three parts of evaporating part 7 of steam layer, a boiling part 8, and a fuel part 1 are in presence in the container 2 during combustion. Solidified fuel is desirable as a fuel 1 to be charged in the container 1, so as not to be effused during handling it before using it. The evaporating rate of fuel 1 is increased and combustion velocity is increased, if the heat receptor part 4 is extended further to increase the rate of heat to be received. On the contrary, combustion flames 5 can be made small, if heat is radiated to the outside from the metallic container 2.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The invention relates to a method and a combustion tool for burning aliphatic lower alcohols, which are generally useful for heating, lighting, and the like.

(Prior art) Conventionally, in order to burn aliphatic lower alcohols such as methyl alcohol and ethyl alcohol and use them for heating, it was necessary to suck them into a wick and burn them, or to burn them by turning them into solids. There are ways to use it as fuel. In the former case, special equipment such as an alcohol rung is required, and in the latter case, handling is easy due to solidification, but
Until now, there has been no known method to burn this steadily with a gentle flame like in traditional candles or lunggs.

(Problems to be Solved by the Invention) This invention provides a simple method for steadily burning these alcohols with a stable flame under desired flame size and combustion conditions without using a wick; This applies to the combustion tool.

(Means for Solving the Problems) The present invention is directed to filling a fuel containing an aliphatic lower alcohol as a main ingredient into a container equipped with a metal heat conductor, and transferring a part of the heat conductor to a combustion section above the container. The heat receiving part is made to protrude, and the other part is used as a heat radiating part and is brought into contact with the fuel in the container. After ignition, the combustion heat is conducted to the fuel through the heat conductor, heating and vaporizing it, and the vapor is released. A method for burning an aliphatic lower alcohol, which is characterized by burning it in a combustion section, and a combustion tool for the same.

The aliphatic lower alcohol which is the main ingredient of the fuel used in the present invention is one having a boiling point of about 50°C to 200m such as methyl alcohol, ethyl alcohol, clovir alcohol, inclovir alcohol, and ethylene glycol.

The present invention is carried out by burning these fuels in a special container in the form of liquid or glue. This will be explained below with reference to the drawings. FIG. 1 is a vertical cross-sectional view showing an embodiment of the combustion tool of the present invention. FIG. 2 is a perspective view of FIG. 1. In FIGS. 1 and 2, a container 2 with a bottom and an open portion at the top is filled with liquid or glue fuel IFi to its upper end. In addition, a part of the heat conductor 3Fi by bending the metal wire 2') protrudes as a heat receiving part 4 in the combustion part above the container 2, that is, in the position where the combustion flame is generated. It is in contact with the fuel l in the container 2 as a heat radiation part 5.

The material of the container 2 is metal or glass.

A flame-retardant material such as ceramic is preferable, and the heat conductor 3 transfers the combustion heat to the fuel I through the heat receiving part 4 which protrudes from the middle pressure of the combustion flame.
It is preferable to use a material that conveys K and has good thermal conductivity and high heat resistance, and its shape can be arbitrary, such as wire, twisted wire, plate, or mesh rod, and there is no particular restriction on the number.

In the method of the invention, in order to burn the fuel 1, the container 2
After holding the fuel 1 vertically, ignite the upper end of the fuel 1 with a matchstick or the like. FIG. 3 shows the combustion situation of the embodiment shown in FIG. 1, in which combustion heat is transmitted from the heat receiving part 4 of the heat conductor 3 protruding into the combustion flame 6, transmitted through the heat conductor 3, and transferred to the heat radiating part 5, where it is transferred to the fuel. Heat l. The fuel IFi is heated to its boiling point, evaporates, mixes with air in the open part of the container 2, and ignites and burns.

That is, during combustion, three parts of the vapor layer, the vaporizing part 7, the boiling part 8, and the fuel l, exist in the container 2.

In the present invention, it is desirable that the filled fuel IFi be solidified into a glue-like shape so that it will not flow out during handling before use. However, glue-shaped fuel is troublesome to fill into a container, and when heated to the boiling point, it does not boil gently and sometimes bumps, so the glue has a low viscosity when heated, and solidifies at room temperature. eg dibennolidene lupitol are particularly preferred gluing agents.

Dipennolidene rubitol is derived from the condensation reaction of sorbitol and benzaldehyde, and this alcohol has the property of disintegrating upon heating and decreasing its viscosity.

In the present invention, this strong gluing agent may be heated and dissolved in fuel, then poured into a container, and allowed to cool and solidify.

At this time, the heated solution can be easily poured into the container 2 because of its low viscosity. In addition, even when heated to 9 boiling points during use, the viscosity becomes low again, and small bubbles are generated to uniformly vaporize without causing bumping. good.

In the combustion tool of the present invention, a lid or a stand for fixing the container may be provided. Further, the container 2 may be made of metal, and the heat receiving portion 4 may be provided at the upper end of the container 2 to serve as the heat conductor 3. FIG. 4 shows an embodiment of the present invention, in which a part of the upper end of a metal container 2 is extended to form a heat receiving part 4.

In the present invention, the size of the flame and the burning rate are controlled to promote or suppress the evaporation rate of the fuel 1 in the container 2! ! i1
M can be adjusted. The amount of evaporation of this fuel 1 is determined by the amount of heat supplied from the heat conductor 3, the dissipation of heat from the container 2 to the outside, etc., so if the heat receiving part 4 is further extended to increase the amount of heat received, the evaporation of the fuel 1 As the amount increases, the firing becomes more active, and if a small amount of heat is radiated from the metal container 2 to the outside, the combustion flame 5
can be made smaller.

(Example) Example 1 A copper strand with a wire diameter of 1.355 m was placed in a bottomed aluminum container with a height of 35 cm, an inner diameter of 8.5 wax, and a wall thickness of 0.75 sx, as shown in Fig. 1. It was folded and inserted as a heat conductor, and both ends were made to protrude above the container as heat receiving parts for 6 days. When I filled this with methyl alcohol up to the top of the container and lit it with a match, it turned out to be about 3.
It burned gently for about 7 minutes with a ~45-ton flame.

Example 2 1.5 parts of dibenzylidene sorbitol (trade name: Gluol D, manufactured by Shin Nippon Rika) was added as a gluing agent to 98.5 parts of methyl alcohol, and the mixture was heated and stirred at about 60°C to dissolve. The mixture was poured into a container equipped with the same heat conductor as in Example 1 up to its upper end and allowed to cool to obtain a glue that solidified at room temperature.

When ignited nine times as in the example, it was stable at about 35 to 40.
It burnt gently for about 7 minutes with a flame of 500 m.

Example 3 Add 1.3 parts of dipenolidene sorbitol to 98.7 parts of ethyl alcohol, heat and dissolve at about 75°C, and pour this into the heat receiving part FI+) at the top of the container as shown in Figure 4. death,
It was left to cool to form a solid glue. When I lit this, it was about 30
The flame rose ~70m and burned for about 3 minutes.

Example 4 Two twisted copper wires with a wire diameter of 1.35 m were used as heat conductors in a glass bottle with a height of 45 m, an outer diameter of 16.5 m, an inner diameter of 7.5 wm, and a photoperiod of 8.5 m. Inserted. The length of the heat receiving part is 6
I made it with cod. A solution prepared by heating and dissolving 1.3 parts of dibenzylidene sorbitol in 98.7 parts of ethyl alcohol at a processing temperature of 75° C. was poured into the solution up to the mouth and allowed to cool to form a solid glue. When it was ignited, it produced a stable flame of about 30 to 45 meters and burned for about 23 minutes, but during this time the 5", II/ inside was heated through the glass and became transparent and liquefied, and then further vaporized. was often observed.

Burning tools are characterized by transmitting the heat of the combustion flame to fuel via a heat conductor, heating and vaporizing it, and then burning it.

In addition, the combustion tool of the present invention has a simple structure and does not use a wick, so there are fewer troubles, and the flame and combustion time can be adjusted, allowing constant combustion with a stable flame. It is also widely used for emergency purposes and leisure purposes.
