The atomization characteristics of spray-to-spray impingement system was investigated in this study for the purpose of its prospective utilization in continuous combustion burners which are used for boilers etc. Two twin-fluid atomizers were used as impinging spray. The total spray quantity is 35 1/h at maximum. SMD was measured in various cases of QA/QW, spray quantity, impingement angle and impingement distance.
The results obtained in the experiment are as follows;
(1) The SMD after impingement reduced about 1/2, compared with that of a single spray.
(2) The optimum condition (minimum value of SMD) varied with QA/QW and spray quantity. The minimum SMD were attained in the case of the impingement angle 140 deg. and the impingement distance about 30 mm within the range of QA/QW= 0.6-1.0 and spray quantity = 21-35 1/h.
