In this state, the door 40 installed on the front lower side of the first combustion chamber 18 is opened, and the coal 44 is set on the lower side of the double grill 18b using a commercially available lightning bomb or other igniter. At the same time, the oxygen supplier 20a is operated to supply oxygen to the inside of the first combustion chamber 18. After approximately 20 minutes, the coal 44 injected into the first combustion chamber 18 is combusted, and hydrogen and methane are the main components. Coal gas is generated.

The coal gas generated in the first combustion chamber 18 is injected into the second combustion chamber 22 through the coal gas supply pipe 24a constituting the coal gas supply member 24 together with the flame, and at the same time, the coal As oxygen is supplied into the second combustion chamber 22 through the oxygen supply pipe 24b formed around the gas supply pipe 24a, coal gas mainly composed of hydrogen and methane in the second combustion chamber 22 has a turquoise color.

You just have to lift it up and outward.

When the coal gas burner device 10 is used as a home heating device, the oxygen supply 20a does not need to be installed separately, because the calorific value required for home heating corresponds to approximately 10,000 Kcal to 30,000 Kcal. Instead of installing the feeder 20a, if the height of the chimney 30 is set to about 3 to 5 m, it is possible to naturally suck the combustion gas generated in the first combustion chamber and the second combustion chamber 18, 22. Because.

In this case, when the oxygen supplier 20a is not provided separately, an air hole may be formed in the side surface of the oxygen supply chamber 20.

When the calorific value is set to 20,000 Kcal in the coal gas burner device 10 according to the present invention, the amount of coal used is enough to be about 10 Kg / 1, and thus it is not necessary to frequently input coal.

The coal gas burner device 10 according to the present invention can be manufactured from a small amount of calorific value 5,000 Kcal to a large size of 5,000,000 Kcal or more.

Since the coal gas burner device 10 according to the present invention has a combustion rate of 85-95%, smoke and odor are hardly generated, so the coal gas burner device 10 may be installed in a vinyl house that grows crops, and thus may be very useful for growing crops in winter. Of course, it can be applied to household heating devices or various industrial heating systems or drying systems.

According to the present invention, coal gas mainly composed of hydrogen and methane generated in the first combustion chamber is injected into the second combustion chamber together with oxygen to burn coal gas with intense flame in the second combustion chamber. As it is configured to be, it generates a large amount of calories while burning while generating intense turquoise flame like a general gas burner. You can get it.

In addition, once ignited, coal is supplied and operated at the same time, so it can be applied to household or various industrial heating systems. Since the combustion rate is 85-95%, almost no smoke and odor are generated, so it does not pollute the environment. There is.

In addition, the use of coal, which is relatively inexpensive, as a fuel instead of petroleum-based fuel, has a significant effect on the national economy as it can obtain the energy import substitution effect.
