Fadhil S.S.A. 57194030184 6507435998 55812738800 Coal fired boilers; Computational fluid dynamics; Engineering research; Fossil fuel power plants; Superheaters; CFD analysis; Cross sectional area; Flue gas temperatures; Gain insight; Imbalance problem; Steam temperature; Tube leaks; Velocity deviation; Boilers This paper presents a CFD analysis of the flow, velocity and temperature distribution in a 700 MW tangentially coal-fired boiler operating in Malaysia. The main objective of the analysis is to gain insights on the occurrences in the boiler so as to understand the inherent steam temperature imbalance problem. The results show that the root cause of the problem comes from the residual swirl in the horizontal pass. The deflection of the residual swirl due to the sudden reduction and expansion of the flow cross-sectional area causes velocity deviation between the left and right side of the boiler. This consequently results in flue gas temperature imbalance which has often caused tube leaks in the superheater/reheater region. Therefore, eliminating the residual swirl or restraining it from being diverted might help to alleviate the problem. � 2017 Published under licence by IOP Publishing Ltd.
