This paper presents a fundamental investigation of the use of conventional Rankine Cycle, Trilateral Flash Cycle, and wet vapour Rankine Cycle system for the generation of power from Enhanced Geothermal Systems. The paper considers ideal Carnot, Trilateral and Quadlateral cycles, and compares the ideal cases of maximum rate of power production with maximum total electricity delivery. These resu...

Abstract In the effort to enhance recovery of waste energy, data centers are drawing attention because huge amount heat discharged from computer racks. Organic Rankine cycle (ORC) power systems a viable solution exploit servers’ heat, as it is available at very low temperatures. The purpose this study assess feasibility integrating micro-ORC system into cooling and its potential energy saving. ...

LNG (Liquefied Natural Gas) shares in the global energy market is steadily increasing. One possible application of LNG is as a fuel for transportation. Stricter air pollution regulations and emission controls have made the natural gas a promising alternative to liquid petroleum fuels, especially in the case of heavy transport. However, in most LNG-fueled vehicles, the physical exergy of LNG is ...

In this paper, a geothermal and solar-assisted combined system is designed for the electricity cooling of residences. The water from resource heat transfer fluid heated in parabolic trough collector used as source absorption system. organic Rankine cycle (ORC) generates power with cycle. produced supported to grid. Engineering Equation Solver (EES) Aspen Plus program are thermodynamic thermoeco...

Organic Rankine cycle (ORC) power plants are considered as one of the most promising technologies to generate from low temperature heat sources such biomass combustion, industrial waste heat, geothermal and solar thermal energy. A feed pump is a key component an ORC plant circulate working fluid within system. Owing boiling organic fluids, pumps more vulnerable suffer cavitation. Cavitation in ...

Low temperature geothermal systems are an abundant energy resource in New Zealand with over 260 sites with a resource temperature of 150°C and lower. The Organic Rankine Cycle (ORC) is the standard process for low temperature energy conversion with commercial ORCs utilizing temperatures as low as 90°C, with one site at Chena, Alaska (discussed below) utilizing temperatures as low as 74°C. The a...

The organic Rankine cycle (ORC) is an efficient technology for electricity generation from low- and medium-temperature heat sources. In this type of power cycle, the radial inflow turbine option usually selected generation. As a critical ORC component, performance markedly affects efficiency system. Therefore, challenge to model behavior operating with fluids recovery applications. context, var...

Abstract With the process of industrialization, a lot energy is consumed, and low-grade produced in process. To recover low grade heat from flue gas coal-fired power plants, organic Rankine cycle built improves utilization efficiency. Taking six working fluids, R245ca, R245fa, R123, R600, R601, R600a, as an example, referring to exhaust condition 300MW subcritical unit, analysed evaporation tem...
