Thermal Calculating Method Adopted Reburning of the Utility Boiler Furnace

YAN Wei-ping,DONG Jing-lan  
Among all the technologies adopted to reduce NOx,the staged fuel combustion(namely reburning) is an effective method.Based on the combustion and heat release characteristic of reburning,furnace zoned thermal calculation method is improved,the main combustion zone and the reburning zone are considered as two thermal discharge sections in advanced method.And the thermal calculation equation of reburning technology is deduced.Illustration of the furnace checking thermal calculation of 200MW coal fired power plant boiler is presented using the reburning technology,and distribution of heat load and temperature variation of combustion product along the height of the furnace are acquired.
