A design criterion for a high temperature rise, compact burner with minimum length and at fixed fuel, air flowrate6 is established based on the concept of Optimum Size Droplet (OSD) spray. To aid in the design of the optimum spray, the required optimum Sauter Mean Diameter (SMD), the droplet number density are given explicitly In terms of the flowrates and the properties of the sprays at the equivalent injection plan of a combustor. The performance chart representing the relationship between combustion efficiency or temperature rise, the burner length are given as function of the inlet group combustion number of spray. The chart also gives the minimum length and the optimum spray. Based on the simulation of the spray combustion of n—octane, one concludes that approximately 15 to 20% reduction in burner length can be achieved when the ratio of the optimum group combustion number to the non-optimized group combustion number is of the order of 10 or larger, or of the order of 0.1 or smaller. The present approach can be extended to account for the swirling combustor with staging, or in dual annual ∆T combustor of the future generation.
