Abstract
Abstract A combustion apparatus having outer and inner casing walls and an annular combustion liner mounted between them. The combustion liner is supported at its upstream end by brackets extending from the front wall of the liner having a radial slip fit connection with struts connecting the outer and inner casings. An annular diffuser fitting against the front end of the combustion liner and extending from and between the struts supplies air to the front wall of the combustion liner. Fuel is introduced through combined fuel and air inlet structures spaced around the front wall of the liner, these having an outer air entrance, an intermediate mixed fuel and air entrance, and an inner air entrance all flaring at the inner side of the combustion liner front wall to direct the entering air and fuel generally radially from these entrances.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
210 words
Combustion apparatus comprising, in combination, means defining a combustion space and having an upstream wall, the said wall defining at least one opening for admittance of fuel and air; a double-walled boss mounted on the said wall projecting through the opening with the inner wall of the boss flaring downstream of the opening to define a flange, the boss having air entrances at its upstream end to admit air for flow between the walls of the boss and discharge over the upstream side of the flange; a tubular air duct mounted within and spaced from the boss, the air duct having a flaring head overlying and spaced downstream from the said flange; a baffle mounted on the air duct overlying and spaced downstream from the head to direct the air emerging from the duct generally radially of the duct; the said boss and duct defining between them an annular conduit for fuel and air terminating in a flaring discharge port between the said flange and the said head; and means for introducing fuel into the air flowing through the said conduit; flow of air through the boss, the said annular conduit, and the said air duct resulting from a pressure drop across the wall in operation of the combustion apparatus.
Claim 2
Dependent Claim
210 words
Combustion apparatus comprising, in combination, means defining a combustion space and having an upstream wall, the said wall defining at least one opening for admittance of fuel and air; a double-walled boss mounted on the said wall projecting through the opening with the inner wall of the boss flaring downstream of the opening to define a flange, the boss having air entrances at its upstream end to admit air for flow between the walls of the boss and discharge over the upstream side of the flange; a tubular air duct mounted within and spaced from the boss, the air duct having a flaring head overlying and spaced downstream from the said flange; a baffle mounted on the air duct overlying and spaced downstream from the head to direct the air emerging from the duct generally radially of the duct; the said boss and duct defining between them an annular conduit for fuel and air terminating in a flaring discharge port between the said flange and the said head; and means for introducing fuel into the air flowing through the said conduit; flow of air through the boss, the said annular conduit, and the said air duct resulting from a pressure drop across the wall in operation of the combustion apparatus.
Claim 3
Dependent Claim
242 words
Combustion apparatus comprising, in combinatIon, means defining a combustion space and having an upstream wall, the said wall defining at least one opening for admittance of fuel and air; a double-walled boss mounted on the said wall projecting upstream from the opening with both walls of the boss flaring downstream of the opening to define flanges; means mounting the outer flange on the upstream wall; the boss having air entrances at its upstream end to admit air for flow between the walls of the boss and discharge over the upstream side of the inner wall flange; a tubular air duct mounted within and spaced from the boss, the air duct having a flaring head overlying and spaced downstream from the said flange; a baffle mounted on the air duct overlying and spaced downstream from the head to direct the air emerging from the duct generally radially of the duct; the said boss and duct defining between them an annular conduit for fuel and air terminating in a flaring discharge port between the said flange and the said head; means for introducing fuel into the air flowing through the said conduit; means for inducing turbulence in the air flowing through the said conduit to promote atomization and mixture of the fuel with the air; flow of air through the boss, the said annular conduit and the said air duct resulting from a pressure drop across the wall in operation of the combustion apparatus.
Claim 4
