Conceptual design and performance characteristics of firebrick resistance-heated energy storage for industrial heat supply and variable electricity production
… a low-carbon energy grid: FIrebrick Resistance-heated Energy Storage (FIRES). FIRES is a storage technology that takes in surplus electricity, stores the energy as high temperature sensible heat (1200°C-1700°C) in a firebrick storage medium, and outputs the stored heat as hot air when the energy …

Solar Process Heat in the Food Industry – Methodological Analysis and Design of a Sustainable Process Heat Supply System in a Brewery and a Dairy
… reduce energy consumption and CO2 emissions with heat recovery, but also with the integration of solar process heat. Energy efficiency must provide the context, or background, of such considerations, and is therefore a very important aspect of them. It is a complex task to design an efficient heat …

Waste heat recovery from aluminum production
… consumed in aluminum production is lost as waste heat. Approximately 30-45% of the total waste heat is carried away by the exhaust gas from the smelter which is the most easily accessible waste heat stream. Alcoa Fjardaal in east Iceland produces 350 000 tons annually, emitting the 110 °C exhaust …

District heating with low-carbon heat sources and low distribution temperatures
Energy supply sector is the largest source of anthropogenic emissions with a share of more than a third in global greenhouse gas (GHG) emissions. In terms of energy demand, the heating and cooling sector corresponds to more than a half of the global final energy consumption. Urban areas have been …

A contribution to the simplified determination of heat distribution costs in linear and radial district heating networks
District heating networks offer a great opportunity to make a significant contribution to the success of the energy transition, assuming that low-carbon heat supply is achieved. District heating networks have advantages over individual building heat supply systems, such as lower heat generation …

Bedarfsorientierte Raumwärmeversorgung durch dynamische Elektroflächenheizsysteme
This thesis deals with the valuation of heating systems with respect to providing heat in rooms based on the momentary need. Due to the temporal and local changes in the room temperature there are unavoidable effects of overheating, whose kind and size significantly depend on the current heating …

Primary Driving Force in Wood Vacuum Drying
… used. In the cyclic drying, the specimens were heated to the 60 C. The vacuum was pulled to about 18 mm Hg. The vacuum pump was kept running for 140 minutes. It was found that in cyclic vacuum drying, drying rate was not affected by the thickness. However, it was affected by the length. The …
