The scaling laws for flame length of large buoyant diffusion flames have not been established on any basis except simple correlations and the correct parameters to be used in these have not been clearly established. Several possible parameters are discussed and a set of experiments is described in which the effects on the flame length of changing these parameters are investigated. The changes in the parameters are accomplished by diluting natural gas fuel with nitrogen and by heating and diluting the ambient air with products of combustion.
