Wood furniture, construction timber, sawdust, crops, etc., which are widely used in various industrial fields and daily life, are recycled only after the use or tillage, and most of them are classified as waste and landfilled or incinerated. As of 2005, 55.11 million tons, including by-products of trees, were generated and only 1.83 million tons were collected or recycled.

Waste from crops such as trees, leaves, rice straw, etc., which cannot be recycled, is used as part of compost, but is mostly incinerated.

In addition, as chemical wastes, products made of synthetic resins such as tires, vinyls and plastics are recycled only after use, and most of them are classified as wastes and landfilled or incinerated. In the case of landfill, not only the landfill site but also the secondary problem of groundwater contamination is caused by the landfilled waste.In case of incineration, the secondary problem of air pollution is generated by generating toxic gas and smoke that are fatal to the human body. As a result, there are many problems in how to deal with easily perishable waste such as waste synthetic resin.

An example of a technique for solving such a problem is disclosed in Document 1 below.

Document 1 below will be described with reference to FIG. 1 as an incinerator using flammable waste as fuel.

1 shows a cross-sectional view of an incinerator disclosed in Document 1 below. In the conventional incinerator, the first combustion chamber 100 made of a heat-resistant material layer 102, the semi-cylindrical injection nozzle 112 is formed in the lower end of the first combustion chamber 100 in a predetermined direction, the rotary plate A plurality of (111) is installed, a plurality of scaffold (114, 115) is attached to the lower end of the rotating plate 111 along the circumferential surface, the hollow shaft 116 for supplying combustion air to the lower center of the rotating plate (111) It is installed, the overall shape of the rotary plate 111 is a conical combustion device 110, a preheat burner 120, which is installed on the wall of the first combustion chamber 100 above the combustion device rotary plate 111, the first combustion chamber ( 100 has a plurality of nozzles formed in an oblique direction with respect to the inside and is installed on the first oxygen supply pipe 130, the upper portion of the first oxygen supply pipe 130 is installed on the preheat burner 120, the first combustion chamber ( Fuel supply device for supplying flammable waste as fuel to 100 (1) 40), a second oxygen supply pipe 150 installed vertically in the center of the first combustion chamber 100 above the fuel supply device 140 and the first combustion chamber 100 above the second oxygen supply pipe 150. It is configured to include an outlet 160 installed on the wall.

In addition, the fuel supply device 140 receives pressure from the hopper 141 and the hydraulic cylinder 142 which accommodates the combustible waste supplied from the outside, and applies pressure to the waste supplied from the hopper 141 to the first combustion chamber ( It consists of an insulating plate 146 installed between the hopper 141 and the outer wall of the first combustion chamber 100 and the hydraulic cylinder 144 to throw waste into the 100.
