| Abstract: | The exergy concept is introduced in the program design of steam balance for coal chemical plants,which gives stave classification of the effective energy of the process gas,steam and water.Supply and demand are compared according to the different exergy value of their thermal energy and analytic hierarchy process（AHP）,and they are made use of according to their different hierarchies.The paper suggests using the dynamic analytic method in the analysis,treatment and optimization of the complicated dynamic process so as to obtain the very best solution.The paper provides a good illustration to the remarkable energy saving design by the comprehensive use of exergy concept,AHP and dynamic analytic method as compared with that of the conventional design in the steam balance program for coal chemical plants. |
