Compensation Design of Fuel Gas Piping For a Gas Turbine
A method is proposed to compensate the thermal stress of the fuel gas manifold by reserving expansion gap at the piping clamp and the thermal stress of each branch pipe by using metal hose.This method is based on ANSYS simulation results,especial-ly suitable for gas turbine with combustor outside.Then the temperature field of the support and the secondary stress of the ring pipe are checked.The results show that the support design scheme can meet the requirements of secondary stress,and the tempera-ture has little effect on the gas,which can be ignored;secondly,the flow distribution characteristics of each branch pipe under nor-mal working conditions are analyzed by StarCD,and the results show that the non-uniformity of three fuel gases for each combus-tor can meet the design requirements.The design scheme can provide a reference for the design of internal fuel pipeline in practical engineering.
