Flue Gas Turbine Fault Analysis and Improvement Measures

Abstract

The flue gas turbine discussed in this article have relatively backward pneumatic design, low operating efficiency, as well as problems of vibration, catalyst accumulation and fouling etc. It cannot realize better generating power effect because of short running cycle, high failure rate, and low recovery of heat and pressure energy generated of high temperature flue gas. To solve the above problems, this article proposes failure analysis. Flue gas turbine problems appear for the main reasons: the steam of the regeneration standpipe reach the regenerator, lead to catalyst breaking and give rise to a large number of catalyst fines, which causes the third cyclone separator blocked and the flue gas turbine fouled. Then, repair the leakage point of regeneration standpipe, maintain smooth operation,and transform leaf type of flue gas turbine. The flue gas turbine restored power generation status after overhaul. achieve the purpose of high efficiency and long-term stable operation.
