The burning velocities of carbou monoxide-air mixtures containing various amounts of water have been determined using a flabflame burner with heat extraction. The addition of water is then treated as being equivalent to that of molecular hydrogen and oxygen in order to obtain a binary fuel mixture o

The predictions of the Payman and Wheeler and the Spalding mixing rules, which seek to derive Ihe burning ~elocily ofa mixlure of fuels from knowledge of the burning velocities ~ff it,, eomponems, have been compared with the experimental results for lean hydrogen carbon monoxide air flames. It is shown dml the P,'lylnan and Wheeler mixing rule ihils to predicl the burning velocity of the mi:~lure, but thai the Spalding mixing rule predicts it wilh ,'m error of less than ten per cent, provided it is assumed that the components have the same equivalence ratios, The cam parison could not be carried out for rich mixtures because of the experimental difficulty in obtaining a sir:fight-line rcktliou between Ihe burning velocities and the hezfl loss.

Burning velocity measurements using stationary flames have been refined to give results with a mean error as low as \_+ 1 per cent. The method employs nozzle burners and a single pass schlieren system. Precautions have been taken to minimize errors at each stage of the experiments and calculations.
