概要 （図表や脚注は「報告書全文」に掲載しております）

概要 （英文）

In integrated coal gasification combined cycle power generation systems,ammonia in the gasified fuel will be passed through hot-type gas clean-up facility into the gas turbine.The ammonia will be converted to nitrogen oxides in the combustion process ofthe gas turbine.Therefore ammonia removal in coal-gasified fuel would work effectively to reduce NOx emissions in IGCC systems.The fundamental experiments are conducted using thermal reactor and the characteristics of ammonia decomposition are studied.The test results are shown as followings; 1) The ammonia in the fuel will be decreased at 500ﾟC with a small quantity of O2 and NO. 2) The ammonia in the fuel will be decreased with the increase of NO input.At the condition of NO/NH3 equals about 1,the sum of the NH3 and NO emissions will be minimized.
