| Abstract: | The drum water level is an important parameter that features the safety operation of boilers.A lot of factors,including improper configuration,improper installation,improper operation and maintenance,result in difference between the observed value and the actual value of the drum water level,which affects the safety and stable operation of power units.The paper make a probe into the thermal power plants in Zhejiang Province in terms of drum water level measurement and water level protection,summarizes the existing problems and analyzes their causes,and proposes some technical measures for eliminating or reducing the effects of these problems,which can be used as a reference for other projects. |
