QUALITY ISSUES IN RCC CHIMNEY OF POWER PLANTS AND ITS MITIGATIONS

R L Dinesh, E R K Nishok

Abstract: In Modern Power plants are constructed with Chimneys of 275m tall for discharge of hot waste gas at high altitude level. Hot waste gas is carried through flues made up with either brick or steel material supported on RCC wind shield. Construction of RCC shell and flues are challenging due to its height. Quality issues due to dragging in slip forming, improper flue can installations are the major problems faced in chimney construction works. Rectification of these problems are time consuming and very expensive. This paper high light on the quality issues faced in few chimneys, mitigations and rectification of these problems.
