Low-temperature operation of heating systems to enable 4th generation district heating: A review

Energy, 2022
District heating networks increasingly rely on heat pumps, condensing biomass boilers, and excess heat in the transition to sustainable energy systems. Accordingly, district heating operators seek to reduce their networks’ supply and return temperatures to maximise production efficiencies, minimise heat losses from distribution pipes and allow greater ...

Pulled Plug-flow Model for 4th Generation District Heating

IFAC-PapersOnLine, 2019
Abstract The controlling of modern district heating systems requires accurate models and simulation tools. The description and necessary verification of a model that sets these ambitions is a matter of this contribution. The model comes out of the known method - plug flow modelling. The implemented model works on the pulling principle when the amount

The effect of the District Heating Return Temperature Reduction on Flue Gas Condenser Efficiency

Environmental and Climate Technologies, 2020
The use of flue gas condensers proved to be effective in increasing boiler efficiency and achieving primary energy savings. The transition to the 4th generation district heating will lead to temperature reduction in district heating networks.

Port-Hamiltonian Modeling of Hydraulics in 4th Generation District Heating Networks

2022 IEEE 61st Conference on Decision and Control (CDC), 2022
In this paper, we use elements of graph theory and port-Hamiltonian systems to develop a modular dynamic model describing the hydraulic behavior of 4th generation district heating networks. In contrast with earlier generation networks with a single or few heat sources and pumps, newer installations will prominently feature distributed heat generation ...
