TIME-VARIABLE AIR POLLUTANT EMISSION STRATEGIES FOR INDIVIDUAL POWER PLANTS

摘要

The study reported here provides a basis for the evaluation of the feasibility, operational characteristics, and potential cost savings of sophisticated time-variable emissions control systems. The study utilizes two years of data from a site in the Northern Great Plains region. The data are applied to models for defining and evaluation time histories of pollutant omissions which satisfy a J 1 relevant air quality standards and minimize the operational costs of emissions control, Under conservative assumptions as to plant size, effective stack height, etc., the potential for sig¬nificant cost savings is shown through the use of time variable emissions control systems. The study also examines the optimum number of emission models, the impact of alternative operational control cost curves, physical stack height, and maximum pollutant generation rates.
