IVBO-Brugge

District heating since 1984

• Length of 11 km (X2) Heat distribution to a.o. hospital, OCMW buildings, apartments, Aquafin, …

• 125 °C – 80 °C

• Potential heat distribution with 3 furnace lines: 20 MWth (15 MWth with 2 furnace lines)

• Average annual power used by customers: 4,8 MWth

• Large maintenance cost due to isolation leaks

• The search for new customers is hard: Competition with gas (group purchasing) Too expensive

IMOG - Harelbeke

Heat distribution to neighbouring company Nerva (producer concrete vaults)• Floor heating, drying, casting of vaults• Replaces fuel oil consumption of 130 000 l/year• Expandable to double capacity (now 8 lines, 10 lines output per outday)• Design on 500 kW (current oil boiler 810 à 1.000 kWth)

Possibly requires further measurements regarding peak power Related to heat buffering or not?

• Separate circuits!! IMOG||NERVA

2017: 1,85 MW2022: 5,94 MW

21

IMOG - Harelbeke

Pilot project: heat transport with energy containers• Storage of energy in transport medium (water or sodium acetate) in container

at +/- 95 °C• Containers: look like shipping containers, additional features such as

temperature display, grounding, leak proof valves, pressure relief, ..• Subsidies awarded by Flemish Government

22

IMOG - Harelbeke

• IMOG: heat buffer followed by collector which branches off to charging stations (min. 2)

• IMOG and consumer: pipes and facilities to transport heat from or to the container

Consumer’s interior installation is taken over in parallel: the existing heat production enters standby mode, external heat distribution gets priority

IVM - Eeklo

Currently no district heating

Studies:• Late 90’s: study for greenhouse complex, stopped for spatial planning

reasons• Feasability study CORE (College Group T Leuven): first aproach in

collaboration with the city of Eeklo• EANDIS: additional study

conclusion: global district heating for the city of Eeklo (2 scenarios) is not profitable in the current context

• Permanent screening of opportunities for an ‘industrial large-scale consumer’ as starting point for the development of district heating

• New Provincial Spatial Implementation Programme Balgerhoeke as an opportunity for the development of district heating in a future industrial zone

25
