Abstract
In a circulating fluidized-bed gasification system, an ammonia-off gas 30 from an ammonia remover 25 is fed to a catalytic denitrator 15 with a flow rate regulated such that a molar ratio of the ammonia in the ammonia off-gas 30 from the ammonia recover 25 to nitrogen oxides in an exhaust gas 6 from a combustion furnace 1 is kept within a setting range, and a reminder of the ammonia off-gas 30 is fed to the combustion furnace 1.
