本発明は石炭と油とを混合した燃料の製造方法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a fuel mixture of coal and oil.
石炭と油とを混合した燃料を製造する方法とし

排ガス処理プロセスも必要で複雑である。 According to such conventional methods, the ash contained in the coal deteriorates combustion efficiency. As a method for removing this ash content, a method is known in which pulverized coal obtained by crushing coal is granulated in water using oil as a binder. There was no known method for producing a mixed fuel of coal and oil based on granulated coal obtained by such granulation. Furthermore, since granulated coal is subjected to granulation treatment in water, it contains a lot of moisture and adheres to it, and its combustion efficiency deteriorates even when it is used as a mixed fuel with oil. In addition, when producing a mixed fuel of coal and oil simply based on granulated coal, the granulated coal may be subjected to a dryer before production, or the granulated coal may be crushed in the process before being mixed with oil. It is inferred that it is time consuming and that manufacturing efficiency deteriorates. Additionally, dust collection and exhaust gas treatment processes that are attached to the dryer are required and are complicated.
本発明の目的は、燃焼効率の良い石炭・油混合
燃料を製造することにある。 An object of the present invention is to produce a coal/oil mixed fuel with good combustion efficiency.

れる点にある。 The main point of the present invention is that, as a basic process, in a method for obtaining fuel that is a mixture of coal and oil, pulverized coal is granulated using oil as a binder, and then the granulated coal obtained by granulation is heated. It has a process of mixing and stirring in heated oil,
The ash content is removed through granulation, and the moisture attached to or contained in the granulated coal is evaporated and removed during mixing and stirring in hot oil. Furthermore, granulated coal that has been subjected to high temperatures must have oil as its binder. Considering this, the coal is automatically dismantled into pulverized coal when subjected to high temperatures and mixed uniformly into hot oil.

にまで脱灰される。 Next, the pulverized coal 3a is put into an underwater granulation device 4 together with heavy oil as a binder and subjected to conventional underwater granulation processing. The granulated coal 4a obtained by this underwater granulation treatment grows to have a grain size of 0.5 mm to 6 mm, and the ash content is deashed from 8% to 15% to 6% or less on a dry coal basis.

の水分が乾炭ベースで10％以下となる。 Deashed granulated coal 4a has 100% moisture evaporation capacity.
It is put into a mixing and stirring tank 5 together with heavy oil 6 heated to 150 to 200 degrees Celsius, which exceeds 150 degrees Celsius. The mixing/stirring tank 5 is equipped with a stirring device and a warmer, and can heat the contents in the tank and the tank itself. The mixing and stirring tank 5 may have a vertical shape, but a horizontal shape is better for evaporation of water. When granulated coal 4a and heavy oil 6 are stirred in such high-temperature oil with a stirring device, granulated coal 4 subjected to high temperature
A is immediately dismantled and returned to pulverized coal, which is uniformly mixed with heavy oil 6. At the same time, by dismantling the granulated coal 4a, the moisture inside the granulated coal 4a is drained out, and the granulated coal 4a is disassembled.
It is exposed to high temperature together with the water on the surface a, becomes water vapor 7, and is released to the outside of the tank. As a result, the mixing tank 5
The moisture in the coal/oil mixed fuel 8 after being treated in the mixing stirring tank 5 is the same as the moisture in the coal/oil mixed fuel 8 after being treated in the mixing stirring tank 5. is less than 10% on a dry coal basis.

効率良く石炭・油混合燃料８が製造できる。 As described above, the ash content and water content in the coal/oil mixed fuel 8 are reduced, and the combustion efficiency is improved. Furthermore,
The granulated coal 4a, which uses oil as a binder that is easily disintegrated in the high-temperature oil 6, can be easily crushed and mixed with the oil 6 in the mixing stirring tank 5 without applying a strong crushing force, and at the same time removes water at high temperatures. Since it can be removed by evaporation, the coal/oil mixed fuel 8 can be efficiently produced.
