The present invention relates to a household waste carbonization apparatus that enables driving.

In general, the method of disposing of household waste is mainly adopted to transfer the household waste to a landfill site and to bury it in a predetermined place or to burn it in a combustion furnace. As a result, the stack type combustion is mainly used.

This type of combustion does not distinguish wastes with various characteristics, and it is a method of charging by burning them in a combustion furnace, and there is no necessity of pretreatment, while it is impossible to reuse combustion gases generated during combustion and cannot recycle combustion products. There was a problem of refilling unburned combustion products.

Therefore, the present invention has been proposed in order to solve the conventional problems as described above, the object of which is to obtain stable combustion products and by-products before charging and combusting the household waste into the combustion furnace, The aim of the present invention is to provide a household waste carbonization device that makes the characteristics of household waste more homogeneous so that driving is possible.
