CONSTITUTION:A container 2 such as a pouch or a cup is filled with an alcoholic liq. fuel 1 prepd. by mixing an alcohol with water or a sol liq. fuel 1 obtd. by adding an org. polymer sol forming agent and a silicic acid compd., if necessary, to the above-mentioned alcoholic liq. fuel. A gelled or solidified solid fuel 3, such as an alcoholic gel fuel gelled by reacting a metal salt of a higher fatty acid with an alcohol, a hexa solid fuel contg. hexamethylenetramine as the main component, or a solid alcoholic fuel contg. polyoxymethylene as the main component, which is sealed and packaged with a flammable film, if necessary, is embedded in the liq. fuel 1. The container is then sealed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Applications] The present invention relates to the improvement of simple fuels used for leisure, camping, and homes. The aim is to provide a composite simple fuel with excellent characteristics.

[Prior Art] Conventionally, liquid or sol-formed liquid fuels include methanol and carboquine vinyl polymer neutralized with an alkali such as triethylamine. On the other hand, gelled or solidified solid fuels include those made by adding paraffin or wax-specific surfactants to alcohol, or adding dibenzalsorbitol or metal salts of higher fatty acids to alcohol. There were also solid hexafuels containing hexamethylenetetramine as a main component and solid alcohol fuels containing polyoxymethylene as a main component.

[Problems to be solved by the invention] Conventional liquid fuels and solid fuels are all composed of combustible substances, so the burning rate per unit amount is fast, and even if the amount is increased, it will burn for a long time. The problem was that it was not suitable for

In addition, no simple fuel has been found that has combustion characteristics such that the combustion power is strongest in the initial stage, maintains high firepower in the middle stage, and can gradually reduce the firepower in the final stage.

[Means for Solving the Problems] The present invention involves filling a container (2) such as a pouch or a cup with a liquid or solized liquid fuel [1], and also filling a gelled or solidified liquid fuel (1) into the liquid fuel (2). Solid fuel [3]
This is a composite simple fuel in which the above-mentioned container is sealed either singly or in sealed packaging with a combustible film and embedded in the container.

[Example 2] The liquid or sol-formed liquid fuel of the present invention is an alcohol-based liquid fuel obtained by mixing alcohols and water, or an organic polymer-based sol-forming agent is added thereto, or it is gelled or solidified. Solid fuel■ is an alcohol-based gelled fuel that is gelled by the action of metal salts of higher fatty acids and alcohols.
Alternatively, it is a solid fuel containing hexamethylenetetramine as a main component, or a solid alcohol fuel containing polyoxymethylene as a main component.

A composite simple fuel is obtained by embedding gelled or solidified solid fuel [3] alone or in a sealed package with a combustible film in the liquid fuel (1), and sealing the container.

[Effects] If an appropriate amount of water is mixed with the alcohol in the liquid fuel (■), the firepower will be reduced accordingly, but the firepower can be adjusted to the required level. In other words, the combustion time can be significantly extended.

Also, when this liquid fuel [1] is burned in a cup-shaped container, the opening area will also be affected, but for example, if 30% water is added to the liquid fuel and 100g of fuel is burned in a cup-shaped container, can be burned for minutes. This is 3 to 4 times the normal amount.

Incidentally, the organic polymer sol-forming agent and silicic acid compound added to the liquid fuel (1) act as a thickening agent, which not only prevents dripping during use, but also makes it extremely easy to fill containers such as cups.

On the other hand, the thermal power of solid fuel (2) is much stronger than that of the liquid fuel described above. However, the combustion mode is that the surrounding area of the solid fuel usually burns at once except for the ice surface, so for example, in the case of alcohol-based gelled fuel, even if there is a large difference between 20 and 200 g of fuel, the combustion time will be shorter. It usually takes about 15 to 20 minutes.

Therefore, by embedding the solid fuel [3] mentioned above in the liquid fuel filled in the cup, the advantages and disadvantages of the two fuels can be complemented, and the ideal method of burning for a long time with high thermal power and high thermal power in the initial stage can be achieved. Combustion characteristics can be obtained.

Also, depending on the type of solid fuel (■), if it is immersed in liquid fuel (■) for a long period of time, the solid fuel may soften or decompose. Just do it.

[Experimental example] Adjust the liquid fuel ■ and the solid fuel [3] in the proportions shown in Tables 1 and 2 shown on page 7, make a composite simple fuel according to each material number, and fill it into a container. and burn it,
We investigated the color of the flame, the presence of odor, and the burning time.

The composite simple fuel of the present invention is as shown in Table 3 shown in 700,
During combustion, the flames of all samples were pale blue-pink or pale yellow, with no strange odor, strong firepower from the initial to intermediate stages, stable combustion conditions, and long-term combustion of 40 to 60 minutes. Ta.

[Effects] The present invention is a composite simple fuel in which the solid fuel [3] is sealed alone or sealed with a flammable film and enclosed in the liquid fuel (2) filled in a cup or the like, so it can last for a long time. It is a highly practical and useful invention because it can be combusted, and has combustion characteristics such as maintaining high thermal power even in the initial and intermediate stages of combustion, and gradually decreasing the thermal power at the stage just before the end of combustion.
