Abstract: Condensation water of steam boiler is a kind of high quality feed water, the recovery and utilization of which is of great
significance for the energy-saving transformation of steam system. Based on the modification of steam system used in a radioactive
plant, this paper put forward a system of increasing condensate recovery and recovering heat from boiler sewage on the basis of
traditional engineering practices, and carried out comprehensive benefit analysis of the modification project. The results show that
the recovery of condensation water of steam will not only bring enormous economic benefits, but also reduce the heat pollution,
which has a greater role in promoting the improvement of the environment. Adding flash tanks and heat exchangers in the sewage
system, 87.9% of the energy in the boiler sewage is recycled, and 14.2%(mass) of the high-quality water is recovered at the same
time, which bring further contribution to energy saving.
