To stuy the source of NOx discharged by coal fired power plant
an experimental study on a 300 MW subcritical swirl-opposed firing boiler was carried out.NOx emission at outlet of the air preheater
flue gas components and exhaust gas temperature were measured under different unit loads.Conversion rate of fuel-nitrogen to fuel-NOx was calculated based on the fuel-NOx formation mechanism
furthermore
its relationship with indexes such as oxygen concentration
boiler load and efficiency was analyzed.Results show that
the conversion rate of fuel-nitrogen to NOx of the swirl-opposed boiler is between 20% and 30%.Compared to the oxygen concentration
furnace temperature has stronger influence on the fuel-nitrogen transformation.
