NOVELTY - A separation method of hydrogen from biomass waste involves granulating biomass waste to ensure permeability and fluidity, providing volatile material suction tube between oven roofs from kiln bottom and avoiding combustion of volatile material, igniting kiln top inner periphery by electric heat for ignition, ensuring combustion zone by injecting air for centers from kiln top outer periphery, and providing piston in suction tube and taking timing of suction of volatile material.    USE - A separation method of hydrogen from biomass waste.    ADVANTAGE - The activity energy can be covered by producing hydrogen from biomass waste byproduced at the time of agricultural and forestry industries production.    DETAILED DESCRIPTION - A separation method of hydrogen from biomass waste involves granulating biomass waste to ensure permeability and fluidity, providing volatile material suction tube between oven roofs from kiln bottom and avoiding combustion of volatile material, igniting kiln top inner periphery by electric heat for ignition, ensuring combustion zone by injecting air for centers from kiln top outer periphery, providing piston in suction tube and taking timing of suction of volatile material, burning carbon left to surface combustion heat and volatile material decomposition chamber of carbon residue by combustion zone and setting as heat source of volatile material decomposition chamber heating, setting hot section and volatile material decomposition chamber of suction tube as product made from caster and ensuring heat resistance, pushing up by stirring with propeller which inserted biomass waste with piston from kiln bottom and is provided in kiln bottom, drying biomass waste by waste heat after volatile material decomposition, covering soil which got decomposition kiln dry and avoiding heat radiation, attaching suction tube and controlling to radiation around suction tube, providing ash-pin ball and sucking to kiln top inner periphery, and preventing closing by ashes.
