The device has an auger screw heated from outside by flue gas generated by firing wood chips, so as to produce water vapor. A pyrolysis auger (2) is heated from outside, where dried wood chips are filled into a gasification pipe located underneath the pyrolysis auger through a shaft (7). Two gasification augers (4) are fed in opposite directions with respect to each other at a moderate rotation speed so as to obtain higher dwelling time for gasification of biomass. A stumbling auger (10) is subjected to heat by firing fresh material and residue carbon obtained after gasification. |
