The utility model belongs to the technical field of biomass gasification, and discloses a novel clean fuel gas biomass fixed bed gasification furnace which comprises an outer reaction furnace and an inner reaction furnace, the inner reaction furnace is coaxially arranged in the outer reaction furnace, the bottom of the inner reaction furnace and the inner bottom of the outer reaction furnace are arranged at intervals, and a fuel gas generation area is arranged in the inner reaction furnace. The top of the inner reaction furnace extends to the outside of the outer reaction furnace, a furnace bar is fixed in the inner reaction furnace, the outer peripheral wall of the inner reaction furnace and the inner peripheral wall of the outer reaction furnace are spaced to form a gas purification area, and a gas outlet is formed in the side wall of the top end of the outer reaction furnace; a feeding mechanism is arranged above the inner reaction furnace; a bottom opening of the gas purification area is provided with a filtering mechanism; a cooling mechanism is fixed on the outer side wall, corresponding to the fuel gas purification area, of the inner reaction furnace; an ash removal mechanism is mounted at the bottom in the outer reaction furnace, and an ash inlet end of the ash removal mechanism axially corresponds to an opening in the bottom end of the inner reaction furnace. According to the reaction furnace, the temperature is kept stable by absorbing reaction heat, the gasification efficiency is improved, and the purification effect of fuel gas is improved.
