Kawasaki Heavy Industries, Ltd. has recently developed the S5 gas turbine at rated output power of 24 KW for use primarily in driving generators.

This paper describes the engineering difficulties we experienced in developing the combustor for the small gas turbine, and its performance characteristics.

Particular difficulties that confronted us in developing the combustor that uses the airblast atomizer are ignition, combustor lean flame out limit and carbon deposit. To work out these problems, we used a “click baffle” in the airblast atomizer, and optimized combustor configuration and air flow distribution as well.
