“…Calise et al [6] and Manente et al [8] proposed ORC part-load operation in-house analysis tools. In interesting fact is that different approaches are implemented by different authors in terms of expander part-load performance, which corroborates that one-size-fits-all solution does not exist and further investigations are still relevant [25][26][27][28][29][30].…”

Organic Rankine Cycle (ORC) thermodynamic optimization is of critical importance while developing new plants. Optimization procedures may be imed at the highest efficiency as well as cost or sizing minimization. Optimization process is generally carried out for plant nominal rating. At the same time, part-load operation has to be carefully considered in case of waste heat recovery from flue gases coming from internal combustion engines or gas turbines. Gas mass flow and temperature variations are specific to this application, significantly influencing ORC plant performance. Secure prediction of part-load operation is of particular importance for assessment of plant power output, providing stability and safety and utilizing proper control strategy. In this paper design and off-design cycle simulation model is proposed. Off-design performance of the ORC cycle recovering waste heat from gas turbine unit installed at gas compressor station is considered. Major factors affecting system performance are outlined.

The idea of using a heat pump in the heating cycle seems quite attractive at first glance, but requires careful analysis of the effect of the heat pump on the operation mode of the thermal power plant. In this work we analyze the influence of the heat pumps inclusion in deaeration schemes of heating network make-up water on the operating modes of the CHP. All calculations were made for the real scheme of the de-aeration plant DSV-800 of the power unit with a T-100 turbine. The calculations were carried out for three schemes of heat pumps of different capacities. The calculations took into the account various uses of the heat received from the heat pumps.

“…It should be noted, that even if the consumer is equipped with heat recording and regulating devices, and accordingly, he cares about the less consumption, the savings are still relative [16]. The savings are reflected in the consumer, but the efficiency of the whole heat supply cycle is not affected.…”

The article analyzes the current state of the Russian heat power engineering and identifies the main problems in its economic development. From the position of an integrated approach, the problems of the Russian heat supply system are divided into three categories: technological, economic and social. The using electricity for the needs of heat supply is determined as an effective way of solution these problems. In this context the electric heat supply is offered as an alternative to the modern heat supply system. The article identifies the main factors of electric heating, showing its economic advantages over other types of heat supply systems. On this basis the authors justify the prospects of electric heating system from the point of view of economic development of the Fuel Energy Complex and the national economy as a whole.
