Analysis on reasons causing dissolved oxygen in condensate water of 1000MW unit to exceed standard and control measures

Abstract

Abstract: Abstract:In practical operation of the 1000MW unit of Huadian International Zhouxian Power Plant, the dissolved oxygen in condensate water exceeded standard. The factors influencing on the dissolved oxygen in the condensate water, such as the condensate water make up model, the return water temperature of feed pump sealing water, the output of the vacuum pump and the mechanical seal of the condensate pump, were analyzed. The comprehensive control measures were put forward, and the safe and economical operation of the unit was ensured.

Key words: Keywords:dissolved oxygen in condensate water, exceed standard, return water temperature of feed pump sealing water system, vacuum pump, mechanical seal of condensate pump
