The determination of the cleaning parameters of the EDTA coordinative chemical cleaning,the range of cleaning and the technical process in Unit 1,Guohuazhunge-er Power Plant are introduced. The difference between the traditional EDTA cleaning technique and the EDTA coordinative chemical cleaning is also introduced. The problems such as the EDTA cleaning for large range thermodynamic system,the using of deaerator water tank as the temporary preparation tank for EDTA chemical cleaning, and the using of prepositive pump of the water supply pump as circulating power of EDTA chemical cleaning are expatiated and analyzed.
Key words: EDTA; deaerator; chemical cleaning
