ATTAINMENT OF FULLY DEVELOPED FLOW IN AIR DISTRIBUTION DUCT OF BOILER USING CFD ANALYSIS
International Journal of Advance Research and Innovative Ideas in Education(2018)
摘要
In the power plant the gas duct is the major part of the system. In this project the gas duct is used to release the flue gas from the boiler outlet to the economizer input port. For modeling the duct SOLIDWORKS software is used. Here in this project CFD analysis can be used to predict the flow behavior and flow of the gas distributed equally at inside of the ducts. The main objective of this project is analyze the gas duct for even distribution of flow. For even distribution the vanes are used. Totally four cases are tried which consists of a base case without the guide plates and three cases with guide plates are tried. The solution is to get even flow distribution of hot gases inside the duct .Duct model was modified by modeling number of guide plates and angles to get distributed flow of hot gases inside the duct. Finally compare the existing design with modified new design.
