* The recycling ratio is to be increased by maximizing to recover the material to be able to recycle among the total amount to be incinerated

Principle
It consists of grates and combustion plate which repeats the back and forward movement through the oil pressure equipment.
Combustion plate is divided into the section of drying, burning, and post-burning section.

Selection of Disposal Method
Strength and weakness	Current status of supply
Mass Murning possible for the large size waste without pre-treatment Heat recovery easy due to the small change in burning heat value The construction and operation record of performance is the largest. It is stable in terms of technology.

Improper to incineration of wastes in which the moisture content is high (food, sludge) and wastes in which the heat value is high (plastic) Burning ratio is comparatively low

Principle
The simple type in which drying, Pyrolysis, gasification, and high temperature melting are made in one incinerator
The type to melt the object in the high temperature (1,700~1,800°C) by adding a small amount of coke and limestone

Direct Heat of Fusion Dismantling Method
Strength and weakness	Current status of supply
Prior crushing and selection, etc. unnecessary in injecting the wastes in the melting furnace Possible to completely melt the wastes of low heat value in a stable manner Maintenance cost is high by using Coke and limestone as the submaterial Necessary to make the measure to inject the nitrogen gas to prevent the explosion in throwing in garbage and the measure to prevent the explosion of steam in case of discharging the sla	Iwate prefecture 200ton/day×2 machines(Japan) Chiba prefecture 100ton/day×2 machines(Japan) Iwate prefecture 50ton/day×2 machines(Japan) Kowoochi prefecture 70ton/day×2 machines(Japan),..etc.
