Numerical Simulation of the Effect of Arch Nose Structure on Furnace Upper Section Flow Field

Li Yanpeng, Xu Jinyuan (Xi'an Jiaotong University) //Journal of Engineering for Thermal Energy & Power.-1999, 14(6).-428~430  
Based on a porosity conception conducted is a numerical simulation of the flow field in a boiler furnace under various arch nose structures. The effects of such structures on the residual swirl at the furnace outlet and the velocity distribution at the inlet of horizontal gas pass were studied. The study results have been verified by way of a cold state simulation test. They can serve as useful reference data during the design and retrofitting of utility boilers.
