ABSTRACT:
Disclosed is a gas turbine engine provided with an annular pre-mixing chamber and an annular combustion chamber adapted for burning a combustible mixture from the pre-mixing chamber. A plurality of circumferentially arranged injection nozzle sets are located between the pre-mixing chamber and the combustion chamber so that the combustible mixture from the pre-mixing chamber is ejected into the combustion chamber, to cause the mixture to be burnt therein. Each injection nozzle set is comprised of at least two nozzles which are inclined with respect to each other in such a manner that a violent contact of the flows of combustible mixture passed through the nozzles occurs at a location in the combustion chamber causing a turbulence of flow to be generated therein. Thus, rapid and stable combustion can be effected.
