dc.description.abstractExperiments were conducted to study the influence of hydrogen enrichment on heating performance of LPG-fired inverse diffusion flame. Structure of the open flame was first measured to provide a basis for comparison. Heating performance of the inverse diffusion flame burning mixed LPG/hydrogen fuel at various hydrogen fractions was then studied by measuring the heat transfer from the flame to an impingement plate. Heat flux transfer from various points arranged at different burner-to-plate distance (H/dair) and radial distance from stagnation points (r) were measured. The mixed LPG/hydrogen fuel for experimental investigation contained hydrogen fraction ranged from 0% to 50%. The Air jet Reynolds number, which dominates the hydrodynamic characteristics of the impinging inverse diffusion flame, was ranged from 2000 to 4000 in the study. The overall equivalence ratio of the air/fuel mixture was ranged from 1 to 2.2, in order to cover the fuel-lean and fuel-rich conditions. Effect of the non-dimensional burner-to-plate distance (H/dair) on the heat transfer performance was also reported.en_ZA
