The Effect of a Front platen Superheater on Gas Velocity Deviation in the Flue gas Duct of a Tangentially Fired Boiler

/Zhou Yuegui, Dou Wenyu, et al (Xi'an Jiaotong University)  
A cold state modeling test was performed of an imported tangentially fired 600 MW boiler. Systematically researched for the first time were the flow pattern in a superheater platen zone and the effect of the front platen superheater on the gas velocity field deviation in a horizontal flue gas duct. The test results show that the use of a front platen superheater with a symmetric layout and an uneven spacing can further weaken the residual swirl at the furnace outlet and decrease the non uniformity of gas flow velocity in the horizontal gas duct. The conclusion reached in this paper can serve as reference data during the design of new boilers.
