Opis:
Some considerations on the waste heat treatment, heat and power combined generation and principles of the Organic Rankine Cycle and its application are produced. A thermodynamic screening of eight working fluids for Organic Rankine Cycle (ORC) was carried out. All investigated agents were single component fluids. The considered ORC systems operated at the upper temperature in the range Tmax=146-185°C and the lower one Tmin=27-37°C. The highest pressure in the cycles equalled pmax=3500 kPa and pmin=85 kPa. The cycles were run at subcritical pressures and the saturated vapour line was of the overhanging type in all cases. Heat regeneration was not considered in this paper. The heat source for the ORC system was heated air exhausted from the cooling system of an opposed-piston engine. The temperature of this heat at the inlet to ORC was equal to Th,in=230°C. Air was also the heat sink for the ORC with the inlet temperature Tcold,in=20°C. The power output of the ORC, neglecting electric generator efficiency, was kept in the range N=10-11 kW. Calculated thermal efficiencies h held values between 0.121 and 0.164.

Opis:
Organic Rankine cycle (ORC) is considered the most used technology in low temperature heat recovery units for cogeneration (electricity and cold). In this study, the effect of the operating parameters, in particular the condensation and the vaporization temperatures on the performance of the cycle are analyzed. In addition, we developed a new combination of organic Rankine cycle and vapor compresion cycle systems to make cogeneration with a negative cold (-10–0◦C), as well with a positive cold (0–10◦C). Three configurations are examined and studied in terms of energy efficiency, namely the performance of each configuration including net power, refrigeration capacity and overall efficiency, the thermal efficiency for ORC and the coefficient of performance for VCC. The used working fluids are n-hexane for the ORC and R600 for the VCC. We also try to apply this new system to have the cogeneration with congelation temperatures. The results show that, for cogeneration with negative cold, among the three configurations that we have developed, the cycle with recovery is preferable in which it has a better energy performance. For a hot spring of 1000 kW, this cycle can provide simultaneously, a maximum net work of 17 kW and a maximum net cooling capacity of 160 kW and an overall coefficient of the order of 0.3. For the production of positive cold, among the three configurations that we have developed, the basic cycle (without recovery) is the most suitable. With the same source of heat a maximum net work of 65 kW and a net cooling capacity in the order of 1000 kW with a global coefficient in the order of 1.05 is obtained. Our system is not only limited to be exploited for a temperature range between -10 ◦C and 10 ◦C, but can also be used with other fluids for lower temperatures (congelation temperatures).

Opis:
The economics of an ORC system is strictly linked to thermodynamic properties of the working fluid. A bad choice of working fluid could lead to a less efficient and expensive plant/generation unit. Some selection criteria have been put forward by various authors, incorporating thermodynamic properties, provided in literature but these do not have a general character. In the paper a simple analysis has been carried out which resulted in development of thermodynamic criteria for selection of an appropriate working fluid for subcritical and supercritical cycles. The postulated criteria are expressed in terms of non-dimensional numbers, which are characteristic for different fluids. The efficiency of the cycle is in a close relation to these numbers. The criteria are suitable for initial fluid selection. Such criteria should be used with other ones related to environmental impact, economy, system size, etc. Examples of such criteria have been also presented which may be helpful in rating of heat exchangers, which takes into account both heat transfer and flow resistance of the working fluid.

Celem projektu był dobór układu odzysku egzergii chłodu z regazyfikacji skroplonego gazu ziemnego (LNG). Podstawowymi założeniami analizy były małe rozmiary takiego układu jak i jego możliwa mobilność. Stworzono kilka wariantów takiej instalacji składających się z układu ORC, mikro turbiny gazowej lub gazowego silnika tłokowego, którego spaliny dostarczają ciepło do układu ORC odparowując czynnik obiegowy, oraz instalacji odparowania skroplonego gazu ziemnego, którą tworzą wymiennik odparowujący go, który pełni jednocześnie rolę skraplacza czynnika obiegowego w układzie ORC, oraz cysterna z LNG. Następnie każdy z wariantów poddano analizie termodynamicznej oraz oszacowano powierzchnię wymiany ciepła poszczególnych wymienników.
The aim of the project was to select the recovery system of cold exergy from regasification of liquefied natural gas (LNG). The basic assumptions of the analysis were the small size of such a system as well as its possible mobility. Several variants of such installation have been created consisting of an ORC system, a micro gas turbine or a gas piston engine, whose exhaust gas supplies heat to the ORC by evaporating the working fluid and a liquefied natural gas evaporation installation, which is created by the evaporation heat exchanger, which also acts as a condenser of working fluid in the ORC system and the LNG tanker Then, each of the variants was subjected to thermodynamic analysis and the heat exchange surface area of individual heat exchangers was estimated.

Opis:
This paper presents the energy and exergy analyses of some different organic fluids which can be used in an organic Rankine cycle adapted to a municipal solid waste power plant in the frame of energy recovery. The novelty of the study is to adapt a well-known organic Rankine cycle system theoretically to the existing municipal solid waste power plant where the exhaust gas with a temperature of almost 560°C is sent to atmosphere causing both energy loss and air pollution, and also violating the related legislation. The efficient organic fluid that can be used in such a plant is estimated by means of the thermodynamic analyses. It is known that, in a typical municipal solid waste power plant, a considerable amount of energy is sent up from a plant chimney to the atmosphere. This waste energy can be utilized by using an adapted organic Rankine cycle system with a proper organic fluid. In this frame, some different organic fluids were examined and compared thermodynamically in this study. The optimal operation conditions of some organic fluids, R141b, isobutane, R245fa, n-pentane and n-hexane have been evaluated by means of ASPEN and EES software programs. The effects of the outlet temperature of heat source on the energetic and exergetic efficiencies and the net power output at a given pinch point temperature difference were investigated. It can be deduced from the analyses that n-hexane has the highest energetic and exergetic efficiencies at all outlet temperatures of the heat source such as 8.92% and 34.47% at 82.08°C, respectively. It can also be stated that the maximum net power output is obtained by using the organic fluid n-hexane.

In the paper authors undertake the design of hydrostatic bearings and hybrid bearings for a specific application – hermetic high–speed turbogenerators for the electric power generation. The most common hydrostatic bearings are usually oil lubricated. On the contrary, the considered here machines are dedicated for the combined heat and power (CHP) production in organic Rankine cycle (ORC) systems and so the hydrostatic bearings use an organic, oil-free working fluid as the lubricant. The reader will acquire an insight into the special characteristics of hydrostatic bearings. Moreover, a new type of bearings, a hybrid bearing, is introduced, which combine both, hydrostatic and hydrodynamic effects. The designed bearings have been manufactured and their good performance confirmed during tests on a real machine.

Opis:
Consumption of energy is one of the important indicators in developing countries, but a lot of companies from the energy sector have to cope with three key challenges, namely how to reduce their impact on the environment, how to ensure the low cost of the energy production and how to improve the system overall performance? For Polish energy market, the number of challenges is greater. The growing demand for electricity and contemporary development of nuclear power technology allow today’s design, implement new solutions for high energy conversion system low unit cost for energy and fuel production. In the present paper, numerical analysis of modular high-temperature nuclear reactor coupled with the steam cycle for electricity production has been presented. The analysed system consists of three independent cycles. The first two are high-temperature nuclear reactor cycles which are equipped with two high-temperature nuclear reactors, heat exchangers, blowers, steam generators. The third cycle is a Rankine cycle which is equipped with up to four steam turbines, that operate in the heat recovery system. The analysis of such a system shows that is possible to achieve significantly greater efficiency than offered by traditional nuclear reactor technology.

Opis:
Jednym z najważniejszych priorytetów stawianych przed konstruktorami maszyn cieplnych jest zwiększenie ich sprawności oraz ograniczenie ich wpływu na środowisko przez zmniejszenie emisji szkodliwych związków do atmosfery i odpadowego ciepła. Ograniczenia te są wymuszone wzrostem cen paliw, jak i coraz bardziej rygorystycznym normom ekologicznym. Jednym ze sposobów realizacji tego celu jest stosowanie układów rekuperacji energii. Układy te stosowane są zarówno w instalacjach przemysłowych jak i w pojazdach samochodowych i maszynach roboczych. W przemysłowych agregatach prądotwórczych najczęściej stosuje się układy kogeneracyjne wykorzystujące ciepło odpadowe z silnika spalinowego w celach grzewczych lub ciepło odpadowe z procesów produkcyjnych bezpośrednio do wspomagania generowania prądu elektrycznego. Obecnie są opracowywane i częściowo wdrażane układy wykorzystujące obiegi teoretyczne Rankine’a, Ericssona i Stirlinga mające zapewnić dużą sprawność konwersji ciepła.
One of the most important priorities placed before the thermal machine builders is increase in their efficiency and limitation of their influence on the environment by reduction of harmful components and waste heat emission to the atmosphere. These restrictions are enforced by rising fuel prices and increasingly stringent environmental standards. One of the ways of achieving this goal is the use of energy recovery systems. These systems are used in both industrial applications as well as in motor vehicles and working machines. In industrial generator sets are commonly used cogeneration systems that utilize waste heat from the combustion engine for heating purposes or waste heat from the production process directly as the aid to electric current generation. They are currently being developed and partially implemented systems using theoretical Rankine cycles, Ericsson, and Stirling to ensure high efficiency conversion of heat.

The paper presents the results of experimental investigations of the ORC system equipped with the expansion valve simulating microturbine operation. The aim of the research was to verify the correct functioning of the installation components and to access the technical condition of the thermal insulation in the heating and cooling mode with regard to the design assumptions. The research was conducted for different values of medium flow rates. The images were acquired using the thermal imaging camera FLIR E50, which is equipped with a specialized software. On the basis of the experimental results, the heat losses have been estimated, together with the places which were the major source of loss (the so-called thermal bridges). It was shown experimentally that the application of a thermal imaging camera can constitute a simple and fast thermal diagnostics method for installations of this type.

Badania miały na celu sprawdzenie poprawności działania podzespołów instalacji oraz ocenę stanu technicznego izolacji termicznej podczas procesów grzania, chłodzenia i regeneracji w stosunku do założeń projektowych. Badania przeprowadzono dla wybranych natężeń przepływów mediów roboczych. W badaniach wykorzystano kamerę termowizyjną FLIR E50 wraz ze specjalistycznym oprogramowaniem. Na podstawie wyników badań oszacowano straty ciepła instalacji oraz określono miejsca, w których występowały największe straty (tzw. mostki termiczne). Wykazano, że zastosowanie kamery termowizyjnej może być szybką i prostą metodą diagnostyki termicznej tego typu instalacji energetycznych.

The results of investigations conducted on the prototype of vapour driven micro-CHP unit integrated with a gas boiler are presented. The system enables cogeneration of heat and electric energy to cover the energy demand of a household. The idea of such system is to produce electricity for own demand or for selling it to the electric grid – in such situation the system user will became the prosumer. A typical commercial gas boiler, additionally equipped with an organic Rankine cycle (ORC) module based on environmentally acceptable working fluid can be regarded as future generation unit. In the paper the prototype of innovative domestic cogenerative ORC system, consisting of a conventional gas boiler and a small size axial vapour microturbines (in-house designed for ORC and the commercially available for Rankine cycle (RC)), evaporator and condenser were scrutinised. In the course of study the fluid working temperatures, rates of heat, electricity generation and efficiency of the whole system were obtained. The tested system could produce electricity in the amount of 1 kWe. Some preliminary tests were started with water as working fluid and the results for that case are also presented. The investigations showed that domestic gas boiler was able to provide the saturated/superheated ethanol vapour (in the ORC system) and steam (in the RC system) as working fluids.

Opis:
In most production plants, waste heat is usually discharged into the environment, contributing to a reduction in the energy efficiency of industrial processes. This is often due to the low thermal parameters of the carriers in which this energy is contained, such as oils, water, exhaust gases or other post-process gases, which means that their use for electricity production in a conventional Rankine cycle may prove to be economically unprofitable. One of the technologies enabling the use of lowand medium-temperature waste heat carriers is the organic Rankine cycle (ORC) technology. The paper present results of calculations performed to evaluate potential electricity production in ORC using waste heat from a natural gas-fired glass melting furnace. The analysis was carried out assuming the use of a single-stage axial turbine, whose efficiency was estimated using correlations available in the literature. The calculations were carried out for three working fluids, namely hexamethyldisiloxane, dimethyl carbonate, and toluene for two scenarios, i.e. ORC system dedicated only to electricity production and ORC system working in cogeneration mode, where heat is obtain from cooling the condenser. In each of the considered cases, the ORC system achieves the net power output exceeding 300 kW (309 kW for megawatts in the cogenerative mode to 367 kW for toluene in the non-cogenerative mode), with an estimated turbine efficiency above 80%, in range of 80,75 to 83,78%. The efficiency of the ORC system, depending on the used working fluid and the adopted scenario, is in the range from 14.85 to 16.68%, achieving higher efficiency for the non-cogenerative work scenario.

Opis:
In this paper, the thermodynamic investigation on the use of geothermal water (130°C as maximum) for power generation through a basic Rankine has been presented together with obtained main results. Six typical organic working fluids (i.e., R245fa, R141b, R290, R600, R152a, and 134a) were studied with modifying the input pressure and temperature to the turbine. The results show that there are no significant changes taking place in the efficiency for these working fluids with overheating the inlet fluid to the turbine, i.e., efficiency is a weak function of temperature. However, with the increasing of pressure ratio in the turbine, the efficiency rises more sharply. The technical viability is shown of implementing this type of process for recovering low temperature heat resource.

Opis:
The evaporation temperature is regarded as one of the major parameters influencing the organic Rankine cycle (ORC) efficiency. Majority of contributions in literature for ORC cycle analyses treat the heat source as if it had an infinite heat capacity. Such analyses are not valuable as the resulting temperature drops of the heat source needs to be small. That leads to the fact that the heat source is not well explored and in the case of waste heat utilization it can prove the poor economics of the ORC. In the present study cooperation of the ORC cycle with the heat source available as a single phase or phase changing fluids is considered. The analytical heat balance models have been developed, which enable in a simple way calculation of heating fluid temperature variation as well as the ratio of flow rates of heating and working fluids in ORC cycle. The developed analytical expressions enable also calculation of the outlet temperature of the heating fluid.
