Trade-offs in NO/sub x/ control
Further reduction in nitrogen oxides (NO/sub x/) emissions may be technically feasible, but the cost of more stringent flue gas regulations may not be justified. Power plant NO/sub x/ emissions are easier to regulate than those from automobiles. Design and operating changes in utility furnaces and boilers to control emissions are not as evident as other kinds of pollution control equipment, but the increased use of coal and concerns about acid rain may change that. New research on the chemical treatment of flue gas is looking at selective catalytic reduction (SCR) with ammonia. Other programs are studying the origins and transport of NO/sub x/ to identify new opportunities for control as well as new furnace modifications and burner retrofit measures. The transfer of Japanese control technology has been slow partly because of differences in regulations and maintenance practices. 2 figures. (DCK)
