抄録

The latest heavy duty gas turbine is designed to operate with a Turbine Inlet Temperature (TIT) of 1500℃. This elevated temperature results in high thermal efficiency but also can induce relatively high emissions. A new Dry Low NOx (DLN) combustor is developed to improve this class turbine compliance with stringent environmental regulations imposed around world. In addition to targeting an environmentally friendly combustor with lower emissions, the re-designed DLN combustor also improves the stability margin. Verification tests of the new DLN combustor were conducted in a M501G1 gas turbine at MHI's T-Point. In addition to verifying lower emission levels, these tests confirmed a wide stable operation margin as well as the reliability and durability of the components.
