“…Steam Rankine cycles are usually preferred to ORC to exploit waste heat sources with higher thermal capacities (from 10 MW up to hundreds of MW) [23], because of the Comparison of different operating range of heat to power conversion technologies based on bottoming thermodynamic cycles for WHR applications higher efficiency and the lower capital cost due to more standard components [23]. The operating range of this technology can be further extended to power scales lower than 10 MW using micro steam turbines ( Fig.…”

In the European Industry, 275 TWh of thermal energy is rejected into the environment at temperatures beyond 300 °C. To recover some of this wasted energy, bottoming thermodynamic cycles using supercritical carbon dioxide (sCO 2) as working fluid are a promising technology for the conversion of the waste heat into power. CO 2 is a non-flammable and thermally stable compound, and due to its favourable thermo-physical properties in the supercritical state, can lead to high cycle efficiencies and a substantial reduction in size compared to alternative heat to power conversion technologies. In this work, a brief overview of the sCO 2 power cycle technology is presented. The main concepts behind this technology are highlighted, including key technological challenges with the major components such as turbomachinery and heat exchangers. The discussion focuses on heat to power conversion applications and benefits of the experience gained from the design and construction of a 50 kWe sCO 2 test facility at Brunel University London. A comparison between sCO 2 power cycles and conventional heat to power conversion systems is also provided. In particular, the operating ranges of sCO 2 and other heat to power systems are reported as a function of the waste heat source temperature and available thermal power. The resulting map provides insights for the preliminary selection of the most suitable heat to power conversion technology for a given industrial waste heat stream.

“…Inverters for solar stations in their characteristics should differ significantly from the simplest inverters and uninterruptible power supplies, which are widely represented on the market. They should be distinguished by a high level of reliability, high overload capacity, built-in electronic protection systems [11][12]. Currently, "solar" inverters in the Republic of Uzbekistan are not produced by industry, and they have to be purchased for currency funds.…”

Development and design of low power mobile and inexpensive solar stations are important for farmers, individuals, geologists and trotters. The most important aspect is ensuring reliability of units in times of transportation, convenience and operational ease as well as minimum dimensions, low price. All the above will ensure large-scale implementation of solar stations in various applications and utilizations.

“…Different energy conversion processes have different thermodynamic limitations; hence, the power generation efficiency should not be compared with the energy sources that use different kinds of fuels (Rand et al, 2000;Stehlók, 2012;Tanuma, 2017). In the abovementioned energy consumption section, the "gasification" process consumed more fuels than the "incineration" process; thus, the PG efficiency at the "gasification" plants was significantly higher than that at the "incineration" plants.…”
