A FUZZY EVALUATION ON FLUE GAS DESULPHURIZATION TECHNOLOGIES

Fuzzy evaluation method(FEM) is introduced into flue gas desulfurization technology (FGDT) and some kinds of representative FGDT are evaluated by FEM in this paper. The evaluation process is carried out as follows: integrative fuzzy evaluation model is founded, representative fuzzy evaluation object set and evaluation object factor set are chosen, and the reason of choosing evaluation object factor and corresponding subfactor composing are analyzed in detail, membership function is confirmed by Professor Zadeh's membership function, the key weight is given by markings of a vast number of experts. Evaluation process shows that operation cost and investment attract more attention, next is desulfurization efficiency and usability ratio. Evaluation results show FGDT 2 is the best and next is FGDT 6.
