“…The key to the success of the ORC system is the selection of the mass, in determining the heat source and cooling temperature, as far as possible to have a high thermoelectric conversion rate and power generation, the critical operating pressure, temperature, density and so on are influencing factors. Should be reasonable evaporation pressure, environmental protection ODP (ozone depletion), low GWP (greenhouse effect value), low toxicity, non-flammable and non-explosive [18].…”

A fertilizer plant wastewater recycling as a research object, the establishment of ORC (Organic Rankine Cycle, referred to as ORC) cogeneration system, using MATLAB software to simulate the operation of the system was found to change the evaporation temperature, condensing temperature, superheat and subcooling degree of the four factors will have an impact on the performance of the system, in which the evaporation temperature and degree of superheat to improve the performance of the system, the condensing temperature and degree of subcooling have a negative effect on the system efficiency. The evaporation temperature and superheat are favorable factors for improving the system performance, while the condensation temperature and subcooling degree adversely affect the system efficiency. Through the verification calculation of specific working conditions, under the conditions of evaporating temperature 110℃, condensing temperature 27℃, superheating degree 8℃ and subcooling degree 3℃, the thermal efficiency of the system can reach about 25%, and the energy efficiency reaches about 45%. The experimental results show that this designed ORC cogeneration system is able to recycle industrial waste heat to a greater extent, which is of great significance to improve the efficiency of energy utilization.

“…The literature describes the applications of microturbines. Sample items [2,3] can be pointed out in the case of gas turbine plants, while articles [4,5] can be indicated in the case of vapour turbine plants. For electric power generation from low-temperature heat sources, such as geothermal [6,7], ocean [8], or waste heat recovery systems [9], vapour microturbines can be used in conjunction with installations that employ the organic rankine cycle (ORC) [10] or organic flash cycle (OFC) [11].…”

The vapour microturbine set’s mathematical model has been updated to consider the partial admission of turbine stages. Experimental data from two distinct microturbine sets were used to verify the model. The model of the microturbine set was tested under varying operating conditions. Examples of a comparison between the experimental results and simulations are presented and analysed. It has been shown that, when simulating the off-design operation of multistage microturbines, not taking into account power losses due to partial admission may lead to significantly incorrect results. This conclusion does not apply to single-stage microturbines.
