METHOD AND APPARATUS FOR PURIFYING FLUIDIZED BED GASIFICATION GAS |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a method and an apparatus for purifying a fluidized bed gasification gas in which a tar and H<SB>2</SB>S contained in a gasification gas of a solid fuel can be easily and inexpensively removed by using a natural mineral containing CaCO<SB>3</SB>, MgCO<SB>3</SB>and the like and thereby the gasification gas can be sufficiently purified. SOLUTION: A natural mineral gas purification agent containing CaCO<SB>3</SB>and MgCO<SB>3</SB>is activated by firing it in a char combustion furnace (20) provided in parallel with a gasification furnace (10). The activated gas purification agent such as CaO and MgO is used in the gasification furnace (10) to purify the fluidized bed gasification gas. COPYRIGHT: (C)2006,JPO&NCIPI
