Problems solved by technology

[0030] However, in the gasification method of the above-mentioned prior art, in order to improve the gas conversion efficiency, an extremely high temperature is required, and therefore, since the sensible heat loss of the generated gas and the furnace heat loss become large, there is a problem that the gasification performance is poor.
[0031] Moreover, according to the gasification method that performs thermal decomposition reaction and gasification reaction under such high-temperature atmosphere conditions, although it can be applied to the above-mentioned high-calorie raw materials such as waste plastics, it can efficiently realize low-calorie hydrocarbons such as organic sludge. Recycling of chemical waste is difficult
