Particulate matter (PM) in flue gas can exhibit highly variable and dynamic characteristics that are dependent on plant fuels, processes, and control parameters. The main characteristics of interest are mass concentration; particle size, defined by the aerodynamic diameter of the particle; and chemical composition, which relates to the eventual toxicity of the particulate matter in the ambient air outside the stack.
Located on the shores of the Delaware River, Salem Generating Station is situated in an environmentally sensitive area. The Delaware Estuary contains approximately 200,000 acres of salt water marshes fed by numerous rivers and streams. When their operating license came up for renewal, the state of New Jersey required the Public Service Electric and Gas Company to modify their circulating water traveling screens for better fish handling at the Salem Generating Station.
