Accurately finding the location of tubes leakage in power plant boilers has important significance for power stations' safe and stable operation.The methods

which used now to locate the leakage of tubes in power plant boilers

have low accuracy and can't be applied when an acoustic sensor broken.In this paper

a Chan algorithm-based residual weighted algorithm(Chan-RW)is used to locate the leakage of tubes in power plant boiler furnace's three-dimensional space.The location performance of this Chan-RW algorithm was compared with the Chan algorithm through computer simulation.The simulation results show that the location performance of this Chan-RW algorithm is better than the Chan algorithm under conditions with different time differences of arrival(TDOA)error and different numbers of acoustic sensor

and the ChanRW algorithm has a good ability in tolerating fault of acoustic sensors

which can well meet the needs of practical applications.
