| Abstract: | Based on the heat-transfer principle of air pre-heater,the influence mode of the changes of the air flow,the flue gas flow,the air leakage in different locations,to the temperature of the hot air and the exhausting gas is researched.The problem of a pulverized coal fired boiler of a thermal power plant,which the deviation of exhausting flue gas temperature increases to an abnormal extend when the boiler load rise up quickly is analyzed,the fault position and fault reason are located exactly,and the fault is eradicated by equipment maintenance at last.The results of this study have a certain significance to solve similar problems. |
