The Mathematical Model of the Waste Heat Utilization Systems From Iudustrical Waste Gas at Medium to High Temperature

Making use of the optimization method of systems engineering, and according to the schemes of remaining heat recovery system for distinct enterprises, we Can establish the mathematical models of this total system. By solving this model, the optimum parameters for this system can be obtained. The remaining heat recovery engineerings designed with this method must gain the best comprehensive economic effects. The key to this problem is to establish the mathematical models of objective function and restraint function for each subsystems. This paper discusses the method of mode-established, that is suitable for the remaining heat recovery systems from industrial waste gas at medinm to high temperature. It is applicable for the recovery system, in which typical equipments can be arranged arbitrarily. Therefore, it must be in common use.
