EASY AND INEXPENSIVE MOVABLE SIMPLE CARBONIZATION FURNACE

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive metallic carbonization furnace that is released from a work regarding soil in which soil is dug, and in which the soil is used as joint material or heat insulating material, has a size and weight capable of moving, and can carbonize all solid biomass materials from a rice hull to a small log-firewood, wherein its operation is easy.SOLUTION: The inside of a carbonization furnace 1 is provided with a heating combustion chamber 6 of heating carbonization material T, the high temperature combustion gas is raised up to a ceiling space X by an combustion gas exhaust tube 7 of the heating combustion chamber 6 elongating to the vicinity of a ceiling cover 2. The raised high temperature combustion gas passes through a circulation space Y between the outer wall 3 of the sidewall of a double structure and the inner wall 3a in which fine holes are made, passes through a bottom face space Z between a furnace bottom face 4 and a charcoal material placing rooster 5, passes through the circulation hole 6c at the side face of the heating combustion chamber 6 and enters the heating combustion chamber 6 to form a high temperature circulation space. Thus the carbonization furnace 1 has a structure of carbonizing the carbonization material T three-dimensionally in a short time while circulating high temperature combustion gas and carbonization wood gas and while carbonization wood gas burns in the heating combustion chamber 6.
