Volumetric expanders for low grade heat and waste heat recovery applications

Renewable and Sustainable Energy Reviews, 2016
Abstract Power production from low grade heat and waste heat does not only mitigate environmental impact but also improve energy efficiency and reduce energy cost. The type and design of expander for a low grade heat engine are critical and affect the performance, efficiency and cost of low grade heat and waste heat recovery system.

Low-Grade Waste Heat to Hydrogen

2020
Industrial waste heat is a source of energy that is currently not fully utilised. On a global scale, the total amount of waste heat accounts for more than 40% of the total energy use, meaning almost half of the energy consumed is wasted as heat [1]. The waste heat potential in the EU has been estimated to be 304 TWh/year [2].

Desalination Using Low-Grade Heat Sources

Journal of Energy Engineering, 2008
This study evaluated the feasibility of utilizing low-grade heat sources such as solar energy or waste heat from industrial processes for desalination. The premise of the approach is that saline waters can be desalinated by evaporation and condensation of fresh water at near-ambient temperatures at low pressures. Low pressures can be achieved naturally

Multi‐Ionic Hydrogel with Outstanding Heat‐to‐Electrical Performance for Low‐Grade Heat Harvesting

Chemistry – An Asian Journal, 2022
AbstractIonic thermoelectric (i‐TE) materials have attracted much attention due to their ability to generate ionic Seebeck coefficient of tens of millivolts per Kelvin. In this work, we demonstrate that the ionic thermopower can be enhanced by the introduction of multiple ions.

Capillary-driven low grade heat desalination

Desalination, 2017
Abstract A capillary-driven seawater desalination method is presented in this study. The core part of the system is an open heat pipe which distinguishes from the regular heat pipe is that no freshwater flows back to the evaporator, but feeds with seawater instead. An experimental prototype is designed and established, which has proved that nearly 91.

Available electricity loss for low grade heat

Desalination, 1982
Abstract A method is developed to calculate loss of available electricity production due to elevated back pressures used in dual purpose power plants. The method is based on practical data provided by turbine manufacturers for various turbines. The method is applied to calculate specific energy demands for desalinated water.

Upgrading of Low-Grade Coals by Heat Treatment

1985
Low-grade coals, such as subbituminous coal, are generally high in inherent moisture and even if they have been dehumidified they absorb moisture again and dried coals have property of high spontaneous ignition. They,therefore, are not suitable for long distance transportation.

Combined heat and power system driven by low grade heat sources

International Journal of Ambient Energy, 1998
SYNOPSIS This paper outlines the development of a combined heat and power (CHP) system. The system is powered by low grade heat which may be provided by a variety of methods including geothermal, solar and waste heat. Such an energy strategy could give substantial environmental benefit. A computer model has been developed for the system using n-pentane
