NOVELTY - Producing biomass energy comprises crushing bamboo wood slice and/or straw powder pole rod as biomass raw material, then adding the biomass raw material mixture in a basket, then placing in a dry distillation kettle, placing the kettle into a pre-burning roasting furnace for pre-burning process, dehumidifying the dry distillation kettle to convert biomass raw material into biomass gas, removing carbon, wood tar and sulfur dioxide from the biomass gas, separating water using a water separator, filtering the biomass gas using a filter device, and storing the biomass in a storage tank.    USE - The method is useful of producing biomass energy (claimed).    ADVANTAGE - The method is capable of producing biomass energy in short production time, with increased quality and production rate, in an eco-friendly manner.    DETAILED DESCRIPTION - Producing biomass energy comprises crushing bamboo wood slice and/or straw powder pole rod as biomass raw material, then adding the biomass raw material mixture in a basket, placing the basket in a dry distillation kettle, placing the dry distillation kettle into a pre-burning roasting furnace to remove moisture and excess of water as vapor, at temperature of 120-150 degrees C for 60-80 minutes, dehumidifying the dry distillation kettle to convert biomass raw material into biomass gas at 180-330 degrees C for 160-200 minutes, removing carbon from the biomass gas in a carbon roasting furnace at controlled temperature of 205-235 degrees C for 120-240 minutes, separating wood tar from the biomass gas using pyroligneous liquid at 95-105 degrees C, separating wood vinegar liquid residue from the biomass gas, cooling the biomass gas using a cooling device, removing sulfur dioxide in the cooled biomass gas using a sulfur dioxide removing device, separating water using a water separator with a water ring vacuum pump, filtering the biomass gas using a filter device with a screen filter, and storing the biomass in a storage tank through a pipeline. An INDEPENDENT CLAIM is included for a biomass energy production line system.
