The auther have investigated the influence of the initial mixture tempe-rature on the burning velocities of Town Gas, Methane, Propane and Butane-Air Mixtures.The result showed that the maximum burning velocities of these fuel gas, (Sb) max.(cm./sec.) are proportional to the 1.5-1.7 th power of the absolute initial mixture tempearture Ti°K.i.e.(Sb) max=aTi1.5-1.5.
Therfore, where high-speed combustion is requrired, an apreciable gain in rate of heat production J (kcal/mm2.sec.) can be had by increasing the initial mixture temper-ature.For instance, In the case of Town Gas, if the lenght of the inner cone of the flame are constant, Jmax for the initial mixture temperature of 373°K, 473°K and 573°K are respectively 1.4, 2.1 and 3.1 times larger than that for the room temperature.
