The present invention relates to a reactor for a dual fluidized bed for indirect gasification. The reactor comprises: a droplet fluidized bed gasifier (100) that includes a top body (110) having a fluid sand precipitating tank (111b) formed in a funnel shape having the bottom end of which the cross sectional areas decrease downwardly and also includes an ascending pipe (150) that is elongated downwardly from the bottom end of the top body (110), so that raw materials are gasified in order to be produced as a synthetic gas; and a bubbling fluidized bed combustor (200) that includes a central body (210) disposed in order to wrap the surroundings of the ascending pipe (150) from the bottom end of the top body (110) and extend towards the center of the ascending pipe (150) so as to have a char combusting space (211c) therein and also includes a bottom body (250) that wraps the surroundings of the bottom of the ascending pipe (150) from the central body (210) in order to have a combusting air tank (251c) therein, so that fluid sand is produced. The ascending pipe (150) is prepared in order to penetrate the central body (210) and bottom body (250). The fluid sand is circulated in the droplet fluidized bed gasifier (100) and bubbling fluidized bed combustor (200). |
