The operating stability of centralized air supplying and dust removing system (CASDRS) is the guarantee of efficiency and the quality of the cigarette making process. The pressure changing in the network, the value of the flow rate of the branch and especially the system resistance balance are the main evaluate indexes of the system. In this paper, a simulation model of CASDRS is built, as an evaluate tool of the system to analyze stability and energy saving potential. The simulation toolbox MATLAB/simulink is employed to analysis the resistance balance of the system, a pipe-net model is devel...
