6. Case story – WHR boiler in Bulgaria
• Kaolin AD, Bulgaria worked
together with EnergiMidt on a
sustainable solution for
replacement of their existing
WHR boiler that utilises the
waste heat for steam
production.
• The steam is used for various
processes in the production.
• Gas reduction 1 to 1.5 mill.
Nm3 p.a. depending on annual
operating hours equal to 30%.
• Payback time was crucial, and
the investment has break
even within 2 years.

9. Case story – Gas engine in Bulgaria
• An existing natural gas fired heat generator
was used in a drying process.
• The hot exhaust gasses from a gas engine
eliminated the need for natural gas.
• The combined produced electricity
was supplied to the grid at an
attractive feed-in tariff.
• Simple pay-back time was 1,4 years

12. Case story – EnergiMidt new office building
• No external heating supply. A heat pump
supplies server cooling and heats the
building at the same time.
• Only passive cooling during summer time –
no AC
• Cooling by means of:
– Integrated PV panels – function as “sun
glasses”
– High insulation
– Natural ventilation
– Night cooling

15. The sun and the potential
”I'd put my money on the sun
and solar energy.
What a source of power!
I hope we don't have to wait 'til
oil and coal run out before we
tackle that.”
“The photovoltaic effect was
discovered in 1839”
Thomas Edison (1847–1931)

16. The sun and the potential

One hour of sunshine can cover the yearly energy consumption of the world
