Abstract

Предложен способ ступенчатого сжигания топлива при подаче воздуха (28) для сжигания топлива в трубу (12) горелки. Для образования первичного пламени (24) внутрь трубы горелки подают начальное количество топлива. Для образования фронта основного пламени (26) ниже по потоку подают второе количество топлива. Основное пламя (26) стабилизируется ниже по потоку от трубы (12) горелки и на расстоянии от нее. Подачу топлива выполняют так, чтобы первичное пламя (24) горело со стехиометрией более 1,5, в частности более 2,0.
