Abstract
Изобретението се отнася до метод за намаляване отделянето на двуазотен оксид, при който към димните газове, отделяни от кипящия слой, се добавя вещество, осигуряващо водородни радикали, например водородсъдържащо гориво като природен газ или алкохол. В димните газове кислородът се внася заедно с добавката или се добавя в горивната камера. Добавката реагира с кислорода, като температурата на димните газове се повишава в интервала от 700 до 9000с до 950-11000с, като количеството на отделения n20 се намалява с около 10-90%. Добавката може да се впръска в циклон или непосредствено преди него, с цел отделянето на частиците от димните газове или непосредствено преди прегревател в конвекционен участък, или в горивната камера, непосредствено преди газовата турбина. 12 претенции, 3 фигури
