Abstract


In the design and operation of energy intensive systems the problem of improving the efficiency is very important. The main way for solving this problem is optimization. This paper describes the general approach for thermoeconomical optimization systems with linear structure as well as systems with pair interplay of flows. The suggested method is based on building and analysis of special graphs of thermoeconomical expenditure. The method is illustrated by an example of a system optimization for thermal treatment of chlorine water as well as a numerical example of a heat exchanger network optimization with one-time interaction of six-flows
