YUAN Jing-tao, LI Xiao-jun Datang Tuoketuo Power Generation Co Ltd. CAUSE ANALYSIS ABOUT SURPASSING STANDARD SET FOR DISSOLVED OXYGEN IN THE CONDENSATE OF 600 MW DIRECT AIR-COOLED UNIT AND DISPOSAL THEREOF[J]. Thermal power generation, 2009, 38(4): 68-72.DOI:
The harmfulness of dissolved oxygen in the condensate has been briefly expounded.The situation of surpassing standard set for dissolved oxygen in the condensate of 600 MW direct air-cooled unit in Tuoketuo Power Generation Co Ltd has been analysed.It is believed from analysis that the main causes resulting in surpassing standard set for dissolved oxygen are as follows:air leaked into the vacuum system
variation of vacuum in the unit
heavy load of the unit
and high degree of condensate supercooling etc..Combined with actual situation in Tuoketuo Power Generation Co Ltd
the deaerator equipment and system of return water from air-cooled condensate have been retrofitted
solving the problem of surpassing standard set for dissolved oxygen in the condensate.
