摘要：
Mitsubishi Heavy Industries' (MHI) 15 PPM NOx Dry Low NOx (DLN) combustor technology for 1500 degrees C G-class gas turbines is presented. Key design improvements are compared to the 25 PPM DLN combustor: A) Inlet aerodynamics, B) Fuel/air mixing, C) Combustor aerodynamics, D) Acoustic resonator. Tests were conducted to verify the new DLN combustor by installing it in a M501G1 gas turbine at MHI's T-Point combined cycle power plant, with more than 1500 special measurements. The results demonstrate the following capabilities: A) Less than 15ppm NOx operation with turn down to 60% load. B) Stable combustion dynamics at all load levels. C) High combustor ignition reliability. D) Suitable for daily start and stop (DSS) operation, E) Good reliability and durability. F) Retrofitable to existing 501G and 701G gas turbines. The combustor is now in mass production as a MHI's standard combustor.
