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.

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

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

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)
