Project Background
Denmark, known as one of the happiest and greenest countries in the world, has achieved remarkable success in energy conservation and emission reduction. One of the key factors driving this success is the extensive use of district heating (DH) systems.
In Denmark, DH networks are flexible and can utilize the most cost-effective fuel sources — from industrial waste heatto biomass energy. However, strict government control on heating prices means that profit margins for local heating companies are limited. To remain competitive, these companies prioritize energy efficiency and cost reduction.
That’s where BROAD’s double-lift absorption heat pump plays a key role. This innovative system recovers waste heat from boiler flue gas, provides DH, and significantly reduces flue gas temperature — achieving nearly zero emissionswhile maximizing energy efficiency.
Project Introduction
At the Fjernvarme Horsens A/S district heating center, a 60MW wood chip biomass boiler is combined with BROAD’s heat pump system, recovering 4MW of flue gas waste heat to supply heating for the surrounding residential area.
Designed by Ramboll, a leading Nordic engineering firm, this system has become a new benchmark for energy-saving and emission reduction across Northern Europe.
Key Technical Highlights
- Vacuum Monitoring Precision – Equipped with a vacuum meter, the system enables accurate monitoring of internal conditions, ensuring optimal performance.
- Compact & Efficient Design – The BDH1200 heat pump uses a left-right structure, reducing machine height and simplifying installation.
- Dual Functionality – It can cool and heat simultaneously, achieving a temperature difference of 75.5°Cbetween chilled and heating water.
- Maximum Waste Heat Recovery – The flue gas is cooled to around 10°C, ensuring nearly all latent heat is recovered, achieving the highest energy efficiency.
Value of the Project
- Complete Waste Heat Recovery – BROAD’s heat pump fully recovers boiler flue gas heat, cooling it to 10°C, achieving the world’s highest energy efficiency.
- Sustainable Impact – The system saves 3,000 tons of oil equivalent per year, equal to planting 490,000 trees annually, setting a new benchmark for low-carbon district heating.
- Technological Innovation – The world’s largest hot-water-driven single-effect double-lift absorption heat pump marks a significant breakthrough in industrial heat pump technology.
- Simultaneous Cooling & Heating – BROAD’s technology demonstrates how cooling and heating can operate together efficiently, minimizing energy waste.
