The Air Fractional Combustion Reduces The NO_x Emissions Technology The Research

By the ratings combustion reform to 3~# boiler in Wulasha power station,because of operation in the low oxygen condition, thermodynamic type NO_x produced by excessively high flame temperature and fuel type NO_x created by excess oxygen content are limited. Therefore, 3~# boiler's NO_x exhaust is lowered from 982.8mg/Nm~3 to 485.5mg/Nm~3 in 70% load by reform, and the NO_x exhaust content reduces 50.60% which is up to the German old boiler's exhaust standard 50Omg/Nm~3 and is under the current American exhaust standard 614mg/Nm~3 and Chinese exhaust standard 65Omg/Nm~3. The ratings combustion reform of 3~# boiler in Wulasha power station has the demonstration function for the old boilers' reform to reduce the NO_x exhaust in western region of Inner Mongolia using different fuels, operating in different capacity.
