to provide sufficient air fuel mixture and circulation of air within the combustor 8 the airflow head 20 which surrounds the gas fuel delivery members 16 includes axially directed bores 21 and radially directed bores 22 which open to impinge on an upstream portion of the gas fuel delivery member 16 the radially directed bores 22 are positioned within a countersunk conical recess which surrounds the gas fuel delivery member 16 and creates airflow axially along the side wall of the gas fuel delivery member 16 the outer ring of axially directed bores 21 further serves to create an axial flow deflecting the radial flow of gas through gas fuel outlets 17 preferably rectangular though other shapes may be used to create appropriate air fuel mixture aid in circulation within the combustor 8 and direct the gas fuel mixture into the central portion of the combustor for ignition however to further deflect the radial flow of gas fuel exiting through gas fuel outlets 17 the airflow head 20 also includes planar surfaces 19 that create deflector apertures 18 for deflecting the gas fuel ejected from the gas fuel delivery member 16 towards an axial direction with resulting flow of compressed air entering the combustor 8 from the plenum 7.
