To meet strict NOx regulations, Kawasaki Heavy Industries, Ltd. has been conducting a development program of dry, low-NOx combustion system since 1989. In a first step of the development program, a multi-burner type, can combustor has been developed. The test engine, with an output of 1.5 MW, demonstrated NOx emissions below 42 ppm at 15% O2. Following the engine performance tests, a 500 cycle endurance test and a 300 hour test at full load have been conducted to assess the reliability of the combustion system developed. During these tests, no mechanical durability issues arose.
