Abstract


Energy conservation issues of common concern in the world , a large amount of waste heat is wasted especially low temperature waste heat low taste can not be good use in the industrial production . This paper cement industry as the research object , using Matlab software and mathematical partial differential method to optimize the selection of its waste heat power generation . Thermodynamic system constitutes the establishment of the first generation of pure low temperature waste heat power generation mode, by the calculation of the heat of mixing efficiency compared to select the best mode . Flashing portion of the composite flash qi waste heat power generation system using mathematical partial differential method the optimum allocation of the boundary conditions of the relevant parameters , combined with the first generation of pure low temperature waste heat power generation and heat of mixing efficiency is defined using Matlab software fit various parameters and mixed thermal efficiency diagram graphical analysis of selected optimal parameter values ??and the mixed thermal efficiency thermal parameters . Matlab software diagram fitting affect the the the hybrid thermal efficiency largest multiple thermal parameters and mixed thermal efficiency , and comprehensive analysis of the maximum efficiency of the best value and the heat of mixing of the thermal parameters , and select the best composite flash fill gas waste heat power generation system . The selected composite flash qi waste heat power generation system before and after optimization of the economic and social benefits , the results show that the optimized system was significantly higher than that before optimization system . Research projects , deepening the selected pure low temperature waste heat power generation system optimization theory and its programming process , especially the the flash pressure distribution using mathematical partial differential method of derivation , reducing the cumbersome process of program optimization , and graphical analysis of the best hot the work parameter values ??and also reduces the parameter value involved in the programming of a plurality of thermal complicated and difficult to achieve optimization process . Subject conclusions of the flash pressure distribution generic formula of cement enterprises to establish a pure low-temperature waste heat station has important theoretical and practical significance .
