| Abstract: | Based on the principles of techno economic theory and the second law of thermodynamics,the thermal techno economic analysis of investment on waste heat recovery exchanger is carried out by using the dynamic investment recovery period method,net present value method and internal rate of income method,the effects of heat transfer units number(NTU),the heat capacity rate ratio of cold and heat fluids(R)and flow patterns on the profits of waste heat recovery exchangers investment are discussed.The method and conclusions from this paper provide the reference for analyzing the economic rationalization of heat exchangers and other energy saving investment projects in engineering and for making decision of investment on energy saving projects. |
