ABSTRACT
This chapter explores the design of stacks from the point of view of the downwind observer whose task is to determine the connection between stack design, process emissions, meteorology, and, most important, environmental effects. It defines the principal factors which must be accounted for when designing a stack for air pollution control purposes. These factors include: air quality standards, meteorological conditions, and topographical peculiarities. The chapter utilizes the sample problem calculation cannot be expected to yield perfect predictions of ground-level pollutant concentrations. The problem of designing a stack to exploit its air pollution control potential largely reduces to a problem of determining a stack height which will assure nonpolluting performance. Meteorological conditions, as much as any other consideration, determine how a stack should be designed for air pollution control purposes. The siting of a stack along the shoreline of a large lake or along an ocean front may be accompanied by unique air pollution transport phenomena.
