Abstract
CER72-73JEC-SKN28.Prepared under contract to Stearns-Roger Incorporated.Includes bibliographical (pages 16-17).March 1973.Tests were conducted in the meteorological wind-tunnel using 1:200 scale model to determine the distribution of gas concentration resulting from gaseous plumes released from four stacks associated with Maui Electric Company Power-Plant at Kahului Hawaii. The tests were conducted over a model power-plant including all significant structures in the vicinity. Data obtained included photographs and color motion pictures of smoke-plume trajectories and plots of contaminant concentration down wind of the power-plant at ground-level sampling positions. The effects of wind direction and stack height on ground-level concentrations are established. Evaluation of test results revealed that an increase of stack height from 30.48 m to 60.96 m will reduce the maximum groundlevel concentrations by a factor of three to five depending upon the wind direction. Location of stacks upwind of the power-plant structures was found to show distinct improvement of plume characteristics
