Smart energy systems and 4th generation district heating systems [PDF]

open access: yes, 2018
This editorial introduces the 16th volume of the International Journal of Sustainable Energy Planning and Management, which addresses different angles of district heating ranging from the planning of district heating systems and economic incentives for flexible district heating plants to comparisons between low and ultra-low-temperature district ...

Hybrid Oxygen Enrichment and Preheating Strategy for Performance Recovery in Ultra‐Lean Micro–Trapped Vortex Combustors

open access: yesEnergy Science &Engineering, EarlyView.
Ultra‐lean H2 micro‐combustor performance is boosted through regulated O2 enrichment and inlet preheating. A 16‐case Taguchi study (ϕ = 0.3) shows: controlled enrichment and heating increase radiative output and efficiency, but excessive O2/temperature causes flashback.

Operation strategies to achieve low supply and return temperature in district heating system [PDF]

open access: yesE3S Web of Conferences, 2019
Low temperature is the most significant feature of the future district heating (DH) - the 4th generation district heating (4GDH). The revolutionary temperature level (50–55/25°C) will improve the efficiency of heat sources, thermal storages, and ...

Atmospheric River Event Frequency Is the Principal Moisture Driver for Radial Growth of High‐Elevation Southern California, USA Conifers, 1658–2020 CE

open access: yesInternational Journal of Climatology, EarlyView.
Conifers growing in high‐elevation alpine environments in the mountains of Southern California, USA, are highly responsive to atmospheric river (AR) events, which typically produce heavy precipitation over 1–3 days. However, it is the frequency of the AR events, not their magnitude nor annual precipitation totals, that most affects the radial growth of

Lowering Temperature Regime in District Heating Network for Existing Building Stock

open access: yesChemical Engineering Transactions, 2016
Introduction of 4th generation district heating (4GDH) concept is an enormous challenge for district heating (DH) companies in Latvia, since most of the DH systems currently operate at high temperature regime.

Case study on the impact of cogeneration and thermal storage on the flexibility of the power system [PDF]

open access: yes, 2017
This work investigates the optimal operation of cogeneration plants combined with thermal storage. To do so, a combined heat and power (CHP) plant model is formulated and incorporated into Dispa-SET, a JRC in-house unit commitment and dispatch model. The
