Definitions
- the present invention relates to combustible gas.
- a gas cutting method that uses flammable gas to cut a target object is known.
- a mixed gas in which combustible gas is mixed with oxygen gas is combusted, and the object is preheated with the heat. Then, when the object is sufficiently preheated, oxygen gas for fusing is further supplied, and the object is oxidized and cut by fusing.
- the applicant has proposed a combustible gas containing 38% by volume or more and 45% by volume or less of ethylene, with the remainder being hydrogen and inevitable impurities (see Japanese Patent No. 4848060).
- This combustible gas is easy to store, transport, etc., and can contribute to improving the quality of the finished product after gas cutting.
- the hydrocarbon gas contained in the combustible gas contributes to the calorie source, that is, the thermal power, and increases the combustion intensity. For this reason, in the conventional combustible gas, the ethylene concentration is set near where the combustion intensity is maximum, as shown in FIG. In this way, the hydrocarbon gas concentration is generally set to increase the combustion intensity.
- the present invention was made as a result of day and night research and development aimed at developing flammable gas with lower CO 2 emissions as a company that provides flammable gas.
- the purpose is to provide a flammable gas that can reduce the amount of CO 2 generated when cutting objects.
- the amount of CO2 gas generated is determined by the hydrocarbon gas content contained in the combustible gas x the fusing time, so for the above flammable gas, lowering the ethylene concentration has the effect of reducing the hydrocarbon gas content.
- the present invention was completed based on the discovery that this greatly outweighs the effect of a longer fusing time and can greatly reduce the amount of CO 2 gas generated.
- the flammable gas according to one aspect of the present invention is a combustible gas used as a combustion gas for gas cutting of a target, and includes ethylene with a concentration of more than 0% by volume and less than 18% by volume, and the remainder is hydrogen and It is an unavoidable impurity.
- the concentration of ethylene which is a hydrocarbon gas, is suppressed to be lower than the ethylene concentration at which the combustion intensity is maximum, and the reduction in fusing speed is small, so the amount of CO 2 gas generated can be effectively reduced. Can be done.
- the flammable gas is preferably sealed in a container, and the pressure in the container is preferably 1 MPa or more and 50 MPa or less at 35°C.
- the pressure in the container is preferably 1 MPa or more and 50 MPa or less at 35°C.
- the concentration of the above-mentioned unavoidable impurities is preferably 1.0% by volume or less.
- the above-mentioned object is a steel material.
- the combustible gas can be particularly suitably used for cutting steel materials.
- the flammable gas of the present invention can reduce the amount of CO 2 generated when cutting an object.
- FIG. 1 is a graph showing the relationship between ethylene concentration and combustion intensity.
- FIG. 2 is a graph showing the relationship between ethylene concentration and fusing speed.
- FIG. 3 is a schematic diagram showing an example of the flammable gas manufacturing equipment of the present invention.
- FIG. 4 is a graph showing the relationship between ethylene concentration and CO 2 generation amount in Examples.
- the combustible gas according to one aspect of the present invention is a combustible gas used as a combustion gas for gas cutting of an object.
- the above-mentioned object is a metal material that can be cut by flame, or in other words, it is a metal material that oxidizes when exposed to oxygen at high temperatures.
- Examples of the object include steel materials, titanium materials, and the like.
- the above-mentioned object is preferably a steel material, and more preferably a general structural rolled steel material.
- the combustible gas can be particularly suitably used for cutting steel materials.
- the combustible gas contains ethylene with a concentration of more than 0% by volume and less than 38% by volume, with the remainder being hydrogen and inevitable impurities.
- the lower limit of the ethylene concentration is preferably 1% by volume, more preferably 5% by volume.
- the ethylene concentration is preferably less than 18% by volume, more preferably less than 15% by volume.
- the upper limit of the content of the inevitable impurities is preferably 1.0% by volume, more preferably 0.5% by volume, and even more preferably 0.1% by volume.
- the lower limit of the content of the inevitable impurities is not particularly limited and may be 0% by volume.

Examples of impurities intentionally added in this way include nitrogen, oxygen, moisture, and the like.
- the flammable gas is stored under pressure in a container or tank. Above all, it is preferable that the combustible gas is sealed in a container. By sealing the flammable gas in the container in this way, handling efficiency can be improved.
- the pressure inside the container is preferably below the pressure at which the gas sealed in the container does not liquefy, and from the viewpoint of transportation efficiency, the pressure is preferably higher.
- the lower limit of the pressure inside the container is preferably 1 MPa, more preferably 6 MPa, and even more preferably 15 MPa at 35°C.
- the upper limit of the pressure is preferably 50 MPa, more preferably 20 MPa. If the pressure is less than the lower limit, it may be difficult to efficiently transport the combustible gas. Conversely, if the pressure exceeds the upper limit, ethylene may liquefy and become difficult to handle. Since the flammable gas has a relatively low ethylene concentration, it is difficult to liquefy even if the pressure inside the container is relatively high. Therefore, by increasing the pressure, the amount of filling in the container can be increased and the transport efficiency can be increased.
