Title:

BIOMASS GASIFICATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2019/065851

Kind Code:

A1

Abstract:

The present invention provides a biomass gasification device that optimizes the pyrolysis temperature of biomass, the reforming temperature of pyrolysis gas, and the atmosphere thereof to generate a reformed gas containing a large amount of valuable gas, that can prevent clogging and corrosion of piping caused by diphosphorus pentoxide and potassium in ash, and suppress the generation of N2O, and that can also reduce the occurrence of tar and soot. The present invention related to a biomass gasification device that is provided with a biomass pyrolyzer, a pyrolysis gas reformer, and a pyrolysis gas introduction pipe, wherein: the biomass pyrolyzer is further provided with a heat carrier inlet and outlet ports, and performs pyrolysis on the biomass by heat of the heat carrier; the pyrolysis gas reformer performs steam-reforming on pyrolysis gas generated by the pyrolysis of biomass; the pyrolysis gas reformer is further provided with an air or oxygen blow-in port; and the pyrolysis gas introduction pipe is provided on the biomass pyrolyzer-side surface below the upper surface of the heat carrier layer formed in the biomass pyrolyzer.
