To monitor the problem of boiler pipe leaking online in heating power plant, after studying the weak points of boiler pipe and determining the arrangements of monitoring sensors, we have developed an online detecting device. This device has been developed on the basis of utilizing the principle of voice monitoring and the characteristics of the different frequencies between the running noises and the leaking noises. Using the signals magnifying and waves sieving technology, this device can distinguish the abnormal signals. After quick analysis of Fourier alteration technology, we may get an audible signal spectrum. Based on the data transformation technology, the signals are monitored and recorded by a computer. It made possible the following functions:giving an earlier alarm when boiler pipe leaking occurs, determining the leaking points, displaying the leaking noise spectrum, tracing on the developing trend of leaking, monitoring the running noises and dust elimination. It provides an effective method of detecting boiler pipe leaking breakdown.
