Abstract

New emission standards have been introduced and existing standards tightened in Sweden, Denmark and Finland. In addition, fees on NO{sub x} emissions were introduced in Sweden. Information was collected to obtain an overview of plants euipped with NO{sub x} control technology and a database created. The database contains over 110 units with a total installed capacity of 30000 MW fuel input. There are plants equipped with NO{sub x} control in Sweden, Finland as well as in Denmark. The control systems in use are either combustion measures (eg low NO{sub x} burners, over fire air, flue gas recirculation) or flue gas treatment (SCR, SNCR). At the end of 1991, 59 plants were equipped with combustion measures (13600 MW fuel input) and 14 plants with flue gas treatment (2000 MW fuel input). In Denmark, large coal-fired boilers have been equipped with NO{sub x} control technologies. They are mostly on coal-fired boilers in Finland too, however, a few are used there in gas turbines and one in a diesel engine. In Sweden, NO{sub x} control measures are installed at various types of plants, including those burning different fuels from municipal waste to natural gas and using various combustion systems including boilers with burners,  More>>

They are mostly on coal-fired boilers in Finland too, however, a few are used there in gas turbines and one in a diesel engine. In Sweden, NO{sub x} control measures are installed at various types of plants, including those burning different fuels from municipal waste to natural gas and using various combustion systems including boilers with burners, stokers, CFBCs, gas turbines and diesel engines. A large number of plants are equipped with NO{sub x} control in Sweden but most units are rather small, resulting in a low total installed capacity. The NO{sub x} reduction achieved using different measures in commercial installations varies widely. A large number of parameters affect the result such as the type of measure used, fuel, boiler design, plant size, whether the installation is new or retrofit and so on. Different combustion measures reported here result in a percentage NO{sub x} reduction between 15 and 60% for boilers and up to 85% for gas turbines. The results from plants with SNCR vary between 35 and 50% and from plants with SCR between 65 and 95%. (au).}
