Parametric optimization of energy conversion systems based on thermo economic indicators

Modern manufacturing enterprises have a quite complex structure of functioning and management. Moreover, they mostly focused on the issue of not one but several types of products. In this case, there are difficulties of issues to determine the costs of each item of finished goods, and especially of the values of intermediate components of production (semi-finished). Non-obvious is the level of influence on these costs, investments and capital investments, which are related to the acquisition of all types of resources, investment, maintenance of production equipment, its operation (for example, thermodynamic irreversibility of implemented processes in the production process). Thus, now there is a need to create a tool to solve the problems related to complex energy systems that cannot be solved through conventional energy analysis. Under the proposed analysis model for each element of the technical system, its elements, or the whole system equations are compiled, the left side of which grouped all incoming financial flows, and the right side – financial flows leaving the system. Auxiliary equations are of particular importance for determination of the specific values. Their calculates allow to determine the value of the intermediate product industries, and do not change the management decisions even in case of complete failure of production of any end product produced. The proposed method, which is based on justified costs per unit of exergy of mass, heat and work output streams of each element, enables to identify inefficient processes and their impact on the economy of the whole enterprise, that is to carry out a thermo-economic diagnosis of the production process, to evaluate different variants of technical solutions in the design and operation of production facilities from the point of view of profitability. With the proposed method it becomes possible to clarify the costs throughout the technology from the input streams (raw materials) to final products.
