Full Description

A simple design procedure is developed for determining the necessary height of an exhaust stack to produce a specified level of dilution at a nearby air intake. The contributions of internal system dilution, wind dilution and dilution from stack height are considered separately. The three effects are combined to determine the available dilution at a critical windspeed which produces minimum dilution. Wind tunnel and full scale dilution measurements are used to set the necessary empirical constants, and a sample design calculation is presented.
