Abstract
The invention relates to a method and a system for producing synthetic gas from biomass by high temperature gasification, including: feeding raw material, carbonizing, pulverizing the charcoal, and transporting charcoal powder to the gasification furnace for gasification. Prior to pulverizing, the charcoal is reduced to a normal pressure by a decompression feeding system of charcoal, pulverized into powders, and transported to a supercharging feeding system of charcoal powder by normal pressure transport gas. The pressurized charcoal powder is transported to gasifier. The high-temperature charcoal at an outlet of carbonization furnace is cooled to 60-200° C. by a cooler, and transported into the decompression feeding system to be depressurized. The charcoal powder with pressurized is ejected to gasifier by an ejector, pyrolysis gas produced from carbonization furnace is used as carrier gas, and the ratio of solid to gas in the transportation pipe for charcoal powder is controlled at between 0.03 and 0.45 m/mby adjusting the amount of pyrolysis gas for transportation. The temperature of the carbonization furnace is controlled at between 400° C. and 600° C. by adjusting the amount of oxygen.
