SPRAY FLOWS AND FLAMES DATABASE

SPRAY BURNER:

The piloted spray burner shown below comprises of a base, contraction and pilot flame holder. The contraction was manufactured from aluminum and has a contraction ratio of 10:1. The central jet nozzle diameter D is 10.5 mm. The outer diameter of the annulus is 25.0 mm and the lip thickness is 0.2 mm. The pilot flame holder is fixed 7.0 mm upstream of the nozzle exit and holds 72 holes concentrically aligned at 7.0 mm, 9.0 mm and 11 mm radius from the centre and each row contains 24 holes with diameters 0.9 mm, 1.0 mm and 1.1 mm respectively. A co-flow of diameter 104 mm surrounds the burner and the co-flow/burner assembly is mounted in a vertical wind tunnel. The tunnel exit has a cross section of 290 x 290 mm. The co-flow and nozzle exit plane is 59.0 mm downstream of the tunnel exit plane.
