New Energy Saving Technologies in Denitrification System of Steel Enterprises
In the denitrification process,flue gas needs to be heated due to the temperature requirements of denitration reaction are high,more blast furnace gas is consumed so that a large amount of CO2 is generated. In order to achieve the energy conservation and carbon reduction,energy saving type built-in direct fired furnace is used instead of traditional heating furnace. The flue gas is heated with the heat released by igniting the CO in flue gas with energy saving type built-in direct fired furnace so that the consumption of blast furnace gas and carbon emission are reduced as well as temperature requirements of denitrification could be met. The consumption of blast furnace gas is reduced by 17.9％ with energy saving type built-in direct fired furnace,annual CO2 emission reduction of over 35000 t is achieved and annual cost saving could reach over RMB 4 million yuan through applications and comparisons,which could meet the requirements of energy conser-vation and carbon reduction for steel enterprises on the premise of meeting requirements of denitrification reactions.
