Gasified-gas generation system

Abstract

A gasified-gas generation system includes: a combustor that heats a fluid medium; a gasifier into which the fluid medium heated by the combustor is introduced and which gasifies a gasification material with heat of the fluid medium so as to generate a gasified gas; and a cooling mechanism that cools the fluid medium that flows between the gasifier and the combustor. The fluid medium circulates between the combustor and the gasifier. The fluid medium and a residue of the gasification material are introduced from the gasifier into the combustor, and the combustor burns the residue to heat the fluid medium.

         2 . The gasified-gas generation system according to  claim 1 , wherein the cooling mechanism is provided at a downstream side of the gasifier, and cools the fluid medium which flows an upstream side of the combustor. 
     
     
         3 . The gasified-gas generation system according to  claim 1 , comprising:
 a temperature measuring unit configured to measure a temperature of the fluid medium at an inlet of the combustor; and   a control unit configured to control the cooling mechanism based on the temperature measured by the temperature measuring unit so as to cool the fluid medium to be within a preset temperature range.    
     
     
         4 . The gasified-gas generation system according to  claim 2 , comprising:
 a temperature measuring unit configured to measure a temperature of the fluid medium at an inlet of the combustor; and   a control unit configured to control the cooling mechanism based on the temperature measured by the temperature measuring unit so as to cool the fluid medium to a preset temperature range.   
     
     
         5 .

 wherein the cooling mechanism cools the fluid medium in the loop seal.   
     
     
         6 . The gasified-gas generation system according to  claim 2 , comprising a loop seal provided between the gasifier and the combustor and configured to prevent any one or both of an outflow of the gasified gas generated by the gasifier to the combustor and an inflow of a gas from the combustor to the gasifier,
 wherein the cooling mechanism cools the fluid medium in the loop seal.   
     
     
         7 . The gasified-gas generation system according to  claim 3 , comprising a loop seal provided between the gasifier and the combustor and configured to prevent any one or both of an outflow of the gasified gas generated by the gasifier to the combustor and an inflow of a gas from the combustor to the gasifier,
