Abstract
Experimental results are presented for the formation of oxides of nitrogen in the burned gas region of premixed oxy-propane flames burning at atmospheric pressure. The majority of the experiments were conducted using argon-shielded laminar flames, and a lean and a rich flame were studied each containing two different amounts of nitrogen. Data are also presented for a rich oxy-propane flame burning unshielded on a commercial glass blowing torch. The use of mathematical modelling of the rate of nitric oxide in the laminar flames has been investigated. It has been shown that reasonable agreement between experimental and computed profiles can be obtained simply by the use of the two reactions. coupled with K1=107.93cm3 mole-1 sec-1 at 2880 K.
