High temperature stationary gas turbine - has air injectors on outlet to cool exhaust before exhaust enters chimney

摘要

The turbine has a horizontal outlet duct (1) and a vertical chimney (2). There is a silencer (5) in the end of the horizontal duct, and a right angle bend section (3) between the end of the horizontal duct and the bottom of the chimney. It has guide blades (32) running along its diagonal. The horizontal outlet (1) enters (1) enters the bend section (3) with an annular gap (6) round it. This forms an injector through which cold air (61) is drawn in. The outlet (33) of the bend enters the chimney with a similar annular gap (7) round it to form a second injector through which further fresh air (71) is drawn in.
