Abstract : The combustion rate is determined by the rate of the slowest stage; it is therefore possible that, with changes in the operating conditions of the combustion chamber over wide limits, and also with changes in the geometric characteristics of the chamber and the type of fuel, one of the limiting stages may be replaced by another. In the article, the mathematical treatment of the problem is based on data from full scale gas turbine installations. Calculated results are exhibited in a series of curves. The effect of the aerodynamic characteristics on the combustion process is experimentally established, as well as the independence of the flow structure of the pressure of the medium at identical blowing rates. A relation is established for the completeness of combustion as a function of the pressure; this permits the conclusion that the limiting stage in the combustion of liquid fuels with a drop size greater than 0.0001 meters is the vaporization of the drops. There is also established an experimental relationship for the dependence of the completeness of combustion on the parameter which characterizes the relative vaporization time of the drops; this makes it possible to determine the completeness of combustion chamber.
