Dissolvedoxygen is the most important cause to the oxidation corrosion

which is one of the important factors to the safety operation and lifetime of circulating water piping. One new kind of thermal deoxygenation system of heat-supply network make-up water suitable for low-temperature heating reactoris proposed. By adding preheater

deaerator

electric heater and related control valves

the thermal deoxygenation of the heat-supply network make-up water is realized

the main parameters of the hot heat-supply network and deaerator equipment and the deaerator electric power of the 200 MW low temperature heating reactor are determined

and the selection calculation of the main equipments in the system is given for reference.
