Flue
Gas Turbine Fault Analysis and Improvement Measures
Hui Cao, Yan Liu, Chang Ji Lin
Abstract
Authors
propose a failure analysis to address problems experienced by a flue gas
turbine with a relatively backward pneumatic design, low operating efficiency,
vibration issues, catalyst accumulation and fouling.
The turbine 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. Flue gas turbine problems appear
for the following reasons: the steam of the regeneration standpipe reaches the
regenerator, leads to catalyst breaking and results in a large number of
catalyst fines, causing the third cyclone separator to be blocked and the flue
gas turbine fouled.
