“Desalted water” feedwater oxygen treatment dexterously combines the characteristics of water vapor loss in normal operation of unit and the natural saturation of dissolved oxygen in make-up water. It’s a new way to implement oxygenated treatment of boiler feedwater, which is more environmentally friendly and economical. Compared to the conventional oxygen bottles or air oxygen methods, the passivation protection mechanism of the heating surface has no difference in essence, but it’s further improved in the aspects of simple operation, project investment and cost, and reduce the use of dangerous chemical sources. A 350 MW supercritical unit applied this technology in China, after nearly 2 y operation, the cleanliness of the water vapor system and the stability control of dissolved oxygen has achieved successful results. According to operation statistics, the new technology has saved more than 2 million RMB of economic cost for the power plant, and gradually applied in Henan, Guizhou, Hubei, Inner Mongolia and other regions. |
