  • the gasification system according to the present embodiment uses air heated by using the exhaust gas discharged from the reforming furnace 100 as a heat source, the above problem is solved.
  • the second heat exchanger 307 may be omitted when the dryer 301 itself includes a drying heat source.
  • FIG. 12 is a top view showing a first modification of the cutting member 104 according to the present invention.
  • the scraper-like member 320 provided on the upper surface of the cutting member 104 can be formed in an arcuate shape. Thereby, the reaction residue 283 received by the cutting member 104 can be more smoothly dropped downward from the gap 281 with the inner cylinder 101.
  • FIG. 13 is a cross-sectional view showing a second modification of the cutting member 104 according to the present invention.
  • the gasifying agent passage 240 provided in the cutting member 104 may include a gasifying agent retention space 340.
  • a larger amount of gasifying agent can be introduced into the reforming furnace 100, and the gasifying agent is heated from the gasifying agent supply port 161 after being heated by the heat transmitted to the cutting member 104. Can be supplied to.
  • the gasifying agent supply port 161 can be provided on the lower surface (back surface) of the screw blade 160. Thereby, it is possible to further prevent the gasifying agent supply port 161 from being clogged by the carbide 282 falling from above.

Abstract

La présente invention concerne : un four de reformeur qui empêche des résidus de réaction et des carbures n'ayant pas réagi, qui sont soulevés dans le four de se mélanger dans le gaz aqueux en tant qu'impuretés et qui agite efficacement les carbures dans le four, en particulier, dans une région dans laquelle une pyrolyse et une gazéification sont effectuées ; et un système de gazéification utilisant celui-ci. Le reformeur comprend un tube interne, un tube externe, un corps cylindrique creux, un élément de coupe et un arbre de rotation. Le tube interne comporte une partie de section transversale agrandie où la zone de section transversale s'étend depuis une partie inférieure vers une partie supérieure et est formée de sorte que l'aire de section transversale de la partie supérieure soit plus grande que l'aire de section transversale de la partie inférieure. Le corps cylindrique comporte des filets pour agiter les carbures et une pluralité d'orifices de distribution d'agent de gazéification disposés à proximité d'un filet supérieur de deux filets adjacents, verticalement opposés, des filets adjacents, chaque orifice de distribution d'agent de gazéification comprenant un trou formé avec un angle de façon à éjecter un agent de gazéification à une direction plus basse que l'horizontale.
