Abstract

Abstract: The 2 series of Continuous Electro-deionization(CEDI) equipment of Heyuan power plant have been put into operation for four and half years, which is approaching the service life and the quality of the product water deteriorated frequently over the past year. The possible causes for the problem were investigated one by one and relevant measures were proposed respectively, including chemical cleaning, level regeneration, transformation of pipeline, rinse cycle, and replacement of individual membrane block. The results showed that the quality of product water of CEDI equipment returned to normal level after various measures had been taken. As a result, the steam quality of Heyuan power plant is guaranteed and the about-to-expire equipment can work normally, realizing security and economy.

Key words: power plant, boiler feed water, water treatment, whole membrane method, electro-deionization, operation optimization
