An experimental study on initial spray field of edge blowing mixture curtain(EBMC) flame holder was conducted using a particle dynamics analyzer(PDA).The droplet diameter and velocity of the spray were measured downstream of the flame holder at different locations in static air.The feature of initial spray field was analyzed.The initial spray conditions for the numerical simulation of combustion was given based on the experimental results of initial spray field.The calculated results were compared with the experimental data and the empirical calculated data.The results indicate that the application of initial spray field experimental data to the numerical combustion simulation improves the calculated results of temperature distribution and combustion efficiency

and the improvement in the calculation of combustion efficiency is especially obvious.
