The intermediate geological materials were dried and incinerated or crushed in advance as necessary to prevent the heavy waste from flowing out when used for arranging], or they were incinerated into 410 rounds so that they could be used as construction aggregates. , for details regarding melting furnaces,
An industrial waste melting PK configured to incinerate and melt industrial waste or its intermediate footwear in the upper part of a high-temperature hearth made of carbon-based combustible material, and take out the molten material from the lower side of the high-temperature hearth. The purpose is to increase the air flow rate, ma, safety, and operability of the combustion air supplied to the high-temperature hearth in a state with good operability. 2, and increase the concentration of combustion air supplied to the high-temperature hearth. Compared to the case where air 1 is supplied, the amount of combustion air supplied is reduced and the consumption of carbon-based combustible substances, such as coke, is reduced. As a result, the superficial velocity of the rising gas in the high-temperature hearth can be reduced and dust scattering and associated clinker generation can be suppressed. Moreover, it is economical in that it suppresses the large amount of thermal energy that is emitted along with the exhaust gas, and reduces the consumption of carbon-based combustible materials. Small furnaces with a furnace inner diameter of 200 mm or less, which have good heat dissipation properties, and therefore it is difficult to maintain the temperature of the high-temperature hearth at the desired temperature when using simple air as the combustion air. However, in order to enrich the oxygen for combustion, conventionally, oxygen from an oxygen cylinder or A method of supplying vaporized oxygen from a liquid oxygen tank into the air has been adopted, but in this case, there are economic disadvantages due to the high cost of oxygen, and the need to place the oxygen cylinder or liquid oxygen tank in a high-temperature location near the device. There were inconveniences such as the danger caused by the use of oxygen, and the need for special permission for workers and storage facilities to handle oxygen according to high-pressure gas regulations.

By supplying a high amount of air to the high-temperature hearth (2), the amount of combustion air supplied to the high-temperature hearth (2) - (195 to 11 times) the theoretical amount of air for combustion of the carbon-based combustible material supplied to the high-temperature hearth (21). By setting K, the temperature of the high-temperature hearth can be maintained at 1400° C. or higher, which is necessary for taking out the melt.
As a result, the superficial velocity of the rising gas can be made wider than @0Ntd/-.- when air is simply supplied as combustion air, and the consumption rate of carbon-based combustible substances can be increased by simply supplying air as combustion air. l 5 G when using air
-/-・h or more] is also low 100~1g04/Wl@k
This makes it possible to suppress dust scattering and the generation of talin carbon associated with it, and also to suppress the emission of a large amount of thermal energy along with exhaust gas, and to reduce the consumption of ζC carbon-based combustible substances. The furnace can be operated under advantageous conditions, and in addition, when simple air is used as the combustion air, the temperature MW of the high-temperature hearth (!
This makes it possible to operate small furnaces with internal diameters of 3 to 600 mm, which are difficult to maintain.

Since the oxygen concentration of the combustion air supplied to the high-temperature hearth is increased by using @, it is possible to increase the oxygen concentration of the combustion air by using an oxygen cylinder or liquid oxygen tank pipe. In comparison, it is economically advantageous because it does not use expensive and oxygen, and it is also safe because it does not use oxygen cylinders, etc., which have a risk of explosion. The equipment can be used for the desired purpose in good operability without any special workers or legal permits required to handle the enrichment equipment. An industrial waste melting furnace that can be used more conveniently has been obtained.
