Abstract

Experimental values of weak and rich limits, for a wide range of fuel-oxygen-inerts mixtures (H2 , CO, CH4 , C3 H8 , O2 , Ar, He, N2 , CO2 ), are presented for a number of tube diameters. The significance of the results is discussed, and with the use of other published data, a weak limit correlation is proposed that demands knowledge only of the fuel composition, its calorific value, and the specific heat of the stoichiometric products at 298 K. The correlation is applicable to simple or complex mixtures, with or without inert addition, and applies over an initial temperature range from 298–1000 K. It is also capable of application to a much wider range of fuels than those investigated experimentally. The accuracy of the parameter is as good as, or better, than those currently in use.
