Research on atomization characteristic of donkey boiler burner would have important significance for improving thermal efficiency,reducing oil consumption rate,protecting combustion space parts and preventing mechanical fault.In this paper,with the help of the CFD software-Fluent 6.2 solver,the Eulerian-Lagrangian models of CFD method were applied to simulate numerically injection and atomization of donkey boiler spray nozzle.Many data concerning atomization characteristics were obtained.These data could provide references for design,fault diagnosis and choice of donkey boiler spray nozzle.
