PULSATION PHENOMENA DURING COMBUSTION OF NATURAL GAS IN COMBUSTION CHAMBERS OF GAS TURBINES,

Abstract

A qualitative study of pulsatile gas-fuel combustion in large-scale gas turbines was carried out at a gas turbine laboratory using a specially constructed experimental device. Extended tests showed that by generating a controlled flame oscillation one can: (a) avoid the disrupting effects due to accidental high amplitude oscillations; (b) intensify the favorable processes with in the reaction zone; and (c) intensify (when needed) the process of convective heat transfer from the flame to the heat exchange surfaces. The tendency towards pulsed combustion within a chamber consuming natural gas increases with a decrease in the initial temperature of the air and with a decrease in pressure of the admitted gas. The article also reports the effects of different types of burners on the operation of turbines.
