Process waste heat from the refinery for district heating supply in Karlsruhe
2019MiRO requires heat for many processes. To use the heat energy efficiently, the feed product, e.g. crude oil, is at first preheated in heat exchangers with the aid of hot effluent product streams (gas oils) and then heated to operating temperature in process furnaces.

On flow and supply temperature control in district heating systems
Heat Recovery Systems and CHP, 1994This paper discusses how the control of the flow and the supply temperature in district heating systems can be optimized, utilizing stochastic modelling, prediction and control methods. The main objective is to reduce heat production costs and heat losses in the transmission and distribution net by minimizing the supply temperature at the district ...

CONECT. International Scientific Conference of Environmental and Climate Technologies
Absorption heat pumps can lift a lower temperature waste heat source to a higher temperature useful output. In that process, it uses less electricity as an input compared to heat pumps with electrical compressors. Therefore, in some cases, it can be used to lift a lower temperature waste heat source to a higher temperature useful output with less ...
