Het totale energiegebruik in Nederland in 2017 bedroeg 3131 PJ. Het gebruik van warmte heeft daar een groot aandeel in. Dit geldt in nog versterkte mate voor de Nederlandse industrie. Figuur 1 toont het energiegebruik van de Nederlandse industrie in 2016. Het finale energetische gebruik bedraag 685 PJ, waarvan 550 PJ (80%) de behoefte aan warmte...

This report gives a systematic comparison of the energy consumption and the investment- and energy costs for a conventional spray dryer in comparison to three conductive thin film drying processes. The evaluated thin film drying processes are: vacuum drum drying, agitated thin film drying and refractance window drying. The comparison is carried...

A thermoacoustic heat pump is a promising innovative heat pump technology which can be applied in the industry to upgrade industrial waste heat. The thermoacoustic heat pump consists of a regenerator flanked by two heat exchangers and placed in a gas (helium) filled acoustic resonator. An acoustic wave is generated and sustained by an acoustic...

Efficient use of energy and lower global warming emissions can be achieved by applying heat pumps in the industry. Heat pumps can be used to increase the temperature of industrial waste heat to useful temperature levels. This enables the reuse huge quantities of energy that would otherwise be rejected to the environment. However, widespread use...

More than 80% of the total energy use in industry consists of the need of heat in the form of steam at different pressure levels and for firing furnaces. The total industrial heat use together with exothermic heat from chemical reactions is eventually released to the ambient atmosphere through cooling water, cooling towers, flue gasses, and...

Significant energy savings can be obtained by implementing a thermally driven heat pump into industrial or domestic applications [1]. Such a thermally driven heat pump uses heat from a high-temperature source to drive the system which upgrades an abundantly available heat source (industrial waste heat, air, water, geothermal). A way to do this...

Thermoacoustic technology can provide new types of heat pumps that can be deployed in dif-ferent applications. A thermoacoustic heat pumps can for example be applied in dwellings to gener-ate cooling or heating. Typically, space and water heating makes up about 60 % of domestics and offices energy consumption. The application of heat pumps can...

A thermoacoustic engine converts heat into acoustic energy that can be used to drive the reverse cycle in a thermoacoustic heat pump or a linear generator for the production of electrical power. Relatively high acoustic pressure amplitudes are employed in these sys-tems to obtain sufficient power density and power output. Streaming effects will...

Significant energy saving is expected by using innovative heat pump concepts for removal and supply of heat from/to a separation process e.g. distillation systems. Conventional heat pumps provide limited temperature lift in an economical way. New heat pumps are required which can operate at the temperature levels of the distillation column and...
