Comparative Study of ECONOMISER Using the CFD Analysis
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 4
Abstract
This paper presents a simulation of the economizer zone, which allowsstudying the flow patterns developed in the fluid, while it flows along the length of the economizer. The past failure details revelsthat erosion is more in U-bend areas of Economizer Unit because of increase in flue gas velocity near these bends. But it isobserved that the velocity of flue gases surprisingly increases near the lower bends as compared to upper ones. The model issolved using conventional CFD techniques by FLUENT software. In which the individual tubes are treated as sub-gridfeatures. A geometrical model is used to describe the multiplicity of heat-exchanging structures and the interconnectionsamong them. The Computational Fluid Dynamics (CFD) approach is utilised for the creation of a three-dimensional modelof the economizer coil of single column tube. With equilibrium assumption applied for description of the system chemistry.
