This burner forms a curtain flame excellent in variable flame length combustibility. 3.4.1 Structure of burner A small capacity two-stage combustion type SSC burner is closely aligned, bring- Coke ing together each burner's quarl and the secondary air ejection holes. (Fig. 18) 3.4.2 Principle of curtain flame formation (1) Adjacent flames are unified by mutual interference due to the joint use of each quarl and strongly swirled primary air ejection effect. (2) Joint use of secondary air ejection holes and high speed ejection Burner Number Material Capacity (103 kcal/h) of burner of quarl 2.300 20 2.000 16 1,000 20 Castable 2.400 24 1.500 30 4.600 5 1.800 11 Heat '\, 4,600 resistant metal '\, 15.30000 19 1.400 3 1,100 '\, 3,100 66 Castable '\, 17,8500 0 49 1,400 15 700 10 Heat resistant metal 370 1 2,600 11 Castable Roof of furnace I Fig. 18 Structure of SCF burner |
