10. District heating in Wallonia
Statistics :
• 63 % of DH have a length of less than 1 km
• 66 % of DH have a power of less than 1 MW
• More than 55 % of the projects are from the public
sector(municipalities)
• The average size of DH are 400 kWth
• 70 % of the DH use heat from biomass (biomass
boilers, CHP, biogas plant, principally units of small power)
• 5 DH’s of greater power (more than 5 MW) use gas, heat
recovery, geothermal energy w/o oil-fired heating as back-up

15. Energy efficiency (products)
Microniser
Air conditioning /air humidification for industries
The Microniser atomizer, manufactured in Wallonia by the Vangeel
Electrical company, offers a ENERGY-EFFICIENT solution to the
problem of humidification in air processing units.
This rotary atomizer (which comprises a high-speed rotary cylindrical
cage) disperses the water in very fine droplets measuring roughly 20
microns in diameter by means of centrifugal force.
Unlike many other fine spray systems, the Microniser operates without
compressed air or pressurized water and is resistant to blockage. With
the Microniser atomizer, it is at last possible to achieve:
- Optimization of the water supply in the air according to
needs and environment to be conditioned.
Significant water and energy savings ( 3 times less energy ! )

17. Smart Grid / Energy Monitoring
A first: the smart grid in practice, Volt-AIR Project
To demonstrate the advantages of the smart grid
inpractice, Siemens Belgium-Luxembourg has launched two
projects:
• Installation of a mini smart grid (a “micro grid”) at their site
in Huizingen. This grid, which is fed by almost 10,000 m2 of
solar panels, will enable ten electric cars to charge up their
batteries via ten charging poles in Anderlecht and Huizingen.
If the demand for energy rises, the vehicles feed energy back
into the micro grid. The cars are used by Siemens employees
for business journeys.
• Two e-cars are also involved in a joint project between
Siemens and SNCB Holding: this is a unique trial in which the
partners plan to examine the impact of electric cars on
individual mobility. Train stations in Ghent, Liège and
Brussels are to be equipped with Siemens charging poles
and employees can use the electric cars in combination with
the train for travel between home and work.
