ZHANG Ming. CAUSE ANALYSIS OF WATER-WALL LEAKAGES INDUCED FROM TUBE-BURST ON 1025t/h UP ONCE-THROUGH BOILERS AND ELIMINATION THEREOF[J]. Thermal power generation, 2002, (6): 53-55. DOI: 10.19666/j.rlfd.2002.06.017.
The causes of frequent water-wall leakages induced from tube-burst on 1025t/h UP once-through boiler have been analyzed. It is considered that the main causes of said problem are defects existing in boiler design and operation
such as strong thermal sensibility of water-wall tubes
great heat deviation in the furnace
unjustifiable structure of rigid beams and furnace hermetization etc.. Hence
corresponding measures for retrofitting have been put forward.
