95-01: Cooling Tower Noise

The construction of new facilities today, especially electric generation or cogeneration stations require permit approval that contain criteria such as noise limits. These facilities are being installed on ever decreasing smaller plots that causes equipment installation close to property lines. It is convenient frequently to place the cooling tower almost adjacent to the property line, thus imposing a sever noise criteria on the cooling tower. Noise sources in the cooling towers include fan, water, gear reducers, and motors. These noise sources are emitted through the air inlet, fan stack, and casing. Attention to techniques will be evaluated.
