Systems Study of Nitrogen Oxide Control Methods for Stationary Sources. Volume II

摘要

The two-volume report presents the findings, conclusions and recommendations of a systems study of nitrogen oxide NO(x) control methods for stationary sources. The study characterized the nature and magnitude of the stationary NO(x) emission problem for the U.S., assessed existing and potential control technology on the basis of nation-wide cost-effectiveness, and recommended a comprehensive 5-year R and D program on stationary NO(x) control. Available technology is not well developed for controlling stationary NO(x) emissions. Of the potential control techniques assessed, combustion modifications show the most promise because of their relative simplicity and projected low cost. Requirements for the development of a mathematical model predicting the fate of NO(x) in combustion processes have been defined and a first-generating model has been formulated in the study. Combustion flue gas treatment techniques may need to be developed to control NO(x) emissions from large, coal fired electric power plants, since suitable combustion modification techniques may not be feasible for this category of emission sources. Complete details of the NO(x) systems study are presented in Volume II of the report. (Author)
