Economic evaluation of turbogenerators in cargo vehicles

Abstract

Insufficient development of energy saving technologies in the field of transport and cargo carrying, as well as the necessity to improve efficiency of vehicle power generating units promote development of heat recovery systems. Challenging trends of implementation of these technologies are road and railroad cargo vehicles due to continuous loads on the modes similar to steady states. In order to achieve the mentioned tasks, it is possible to apply heat recovery systems based on turbogenerators which increase performances of overall power generating unit and decrease fuel consumption. This article discusses technical and economical performances of vehicle power generating units based on turbogenerators, positive and negative effects as well as reasonability of their application. Competitive variants of developed heat recovery system are analyzed, their advantages and disadvantages are compared and discussed. Consumer properties of the developed turbogenerator are determined for wide scale and long-term application with accounting for payback periods.
