STAGED COMBUSTION METHOD FOR A LIQUID FUEL AND AN OXIDANT IN A FURNACE

The procedure, using a jet or atomized liquid fuel and primary and secondary jets of oxidant, has the primary oxidant jet divided into two separate primary jets, the first injected coaxially round the atomized fuel jet, and the second injected at a distance l1 from the fuel jet. The atomized fuel je...

Beschreibung
Zusammenfassung:	The procedure, using a jet or atomized liquid fuel and primary and secondary jets of oxidant, has the primary oxidant jet divided into two separate primary jets, the first injected coaxially round the atomized fuel jet, and the second injected at a distance l1 from the fuel jet. The atomized fuel jet is produced by coaxial injection of a gas round a jet of liquid fuel, the gas being either air or oxygen, or an inert gas such as nitrogen or water vapour and comprising between 5 and 40 per cent of the liquid fuel jet's mass flow rate. The secondary oxidant jet is injected at a distance from the fuel jet equivalent to between 8 and 40 times the diameter of the secondary jet injector, and the quantity of the secondary oxidant jet is between 50 and 90 per cent of the total oxidant injected.
