Embodiment Construction
[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0031] refer to Figure 1-5 , a control method for slowing down the formation and shedding of oxide scales in the heating pipes of power plant units, the steps of which are as follows;
[0032] S1: Start the boiler, heat the boiler, and start the unit at the same time during the process from the cold state to the warm state to the hot state of the boiler. During the operation of the unit, the inside of the unit will change from a warm state to a wet state to a dry state; in S1 , will first add water source in the boiler, the quality standard of water source is PH value 9.2~9.6, Fe≤50μg / L, SiO2≤30μg / L, conductivity≤0.65μ s / cm, in S1;
[0033] S2: In the process of op...
