Document Type and Number:
WIPO Patent Application WO/2011/048779
Kind Code:
A1
Abstract:
In a circulating fluidized-bed gasification system, an ammonia off-gas (30) discharged from an ammonia remover (25) is supplied to a catalytic denitrator (15) while regulating the flow rate of the ammonia off-gas (30) so that the molar ratio of the ammonia contained in the ammonia off-gas (30) to the nitrogen oxides contained in a discharge gas (6) from a combustion furnace (1) is kept in a predetermined range, and the remainder of the ammonia off-gas (30) is supplied to the combustion furnace (1).
