Power Generation

Noise from the first 45MW IHI LM6000 gas turbine located at Bairnsdale, Australia, generated excessive noise levels when operating at loads of 20 and 30MW. At a load of 40MW the acoustically treated plant complied with the project noise level of 37dBA at a distance of 750m, but at low loads the equipment generated excessive noise levels.
