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.A method for staged fuel combustion with air (28) for fuel combustion in the burner pipe (12) is proposed. To form the primary flame (24), an initial amount of fuel is fed inside the burner tube. A second amount of fuel is fed downstream to form the main flame front (26). The main flame (26) is stabilized downstream of the burner tube (12) and at a distance from it. The fuel supply is carried out so that the primary flame (24) burns with a stoichiometry of more than 1.5, in particular more than 2.0.
