The 600 MW Unit wet flue gas desulfurization in a power plant of China Datang Corpora tion need the capacity extension.The power plant summed up the three kinds of ivable capacity extension schemes, accord-i ng to the actual situation, such as increase the height and layer of the original spray ab sorber, series flue gas sytsem un it with double-absorber, dual-cycle flue gas system unit with double-absorber, each tech nical fea-tures are described ,the advantages and disadvantages of each scheme are compared, combined wtih factors such as performance guarantees, pr oject investment, construction period, etc.The double absorber scheme is more suitable for this project transformati on than single absorber scheme,after comparison and demonstration.
