Abstract:
This thesis is based on a study of the behaviour of the multiple burner systems. The influence of number of burners, their separation and degree of swirl on the interaction of multiple gaseous turbulent diffusion flames, for different configurations chosen, has been investigated. A single flame has been studied as a reference flame to provide information for the comparison with multiple systems. The temperature and concentration profiles within the flames have been determined using thermocouples and a semi-continuous gas sampling system in conjunction with a gas chromatograph. Three orthoganol mean velocity components in the annular air stream of a single isothermal swirling jet have been measured using a hot wire anemometer and by the application of a four point measurement technique developed within the department. Multiple flame systems were found to be less stable against blow-off compared to single flames and the blow-off limit shifted towards the fuel rich region as the swirl was reduced. At low swirl levels and minimum separation the centre flames were lifted off the burner rim and were frequently blown-off.
