FIELD: heating. ^ SUBSTANCE: method includes the setting of value of optimal dissolved oxygen concentration (KO2)pv from the minimum capacities in the limits of possible product concentration in the corrosion KFe under the maintenance of the electroconductivity values chi and of working area vapor-water area section, at the same the optimal value of (KO2)pv is established to chipp/chioc<= 1.5, ()pv-()op<=0.2 (KFe)pp<=10 mkg/dm3, where chipp - the value of vapor electroconductivity after intermediate superheater, chi± - the value of electroconductivity of cleaned turbine condensate, ()pv - nutrient water, ()op - of the direct steam, (KFe)pp - the concentration of corrosion in vapor after intermediate superheater. ^ EFFECT: optimal concentration of dissolved oxygen in nutrient water of power unit with steam - boiler of overcritical pressure provides the minimization of corrosion in the power unit water-vapor. ^ 2 cl, 2 ex |
