The paper reports on an attempt to apply Meurers film vaporization combustion method M-method, originally developed for diesel motors, to the combustion chambers of gas turbines. In the M-method, instead of distributing the fuel in the air, it is laid on the wall of the combustion chamber and evaporated, mixed, and fired by means of the appropriate movement of air - the evaporation rate, as a function of the air velocity, and gas and flame temperature, providing an additional control element for the combustion process. The three points primarily considered are 1 The formation of a fuel film of sufficient surface extent on the wall. 2 The evaporation of the fuel from this wall and its molecular mixing with the combustion air at sufficiently low temperatures and delay times to minimize cracking. 3 The injection of the fuel-air mixture into a combustion zone in which oxidation reactions may first take place.
