In view of the problem of the gasholder design in steel plants， a dynamic design method was proposed to calculate the rational capacity of gasholders under the boiler fuel load regulating frequency matching condition through establishing mathematical model， which obtained good practice application. The case study showed that the determined volume of the gasholder by the application of this dynamic design method was greatly reduced compared with the previous one on the basis of ensuring stable production of byproduct gas system. The operating results were better than the current gasholder designed by the static methods and empirical design values in steel plants. Finally， the best fitting curve of the suitable capacities of gasholder corresponding to different regulating frequencies of boiler fuel load was given using this dynamic design method. The optimal allocation of surplus gas of the steel plants was solved and scientific guidance was provided for the optimization design of gasholder capacity in buffer users of the steel plants.
