ABOUT


 

The Improbed™ concept is a new way of operating fluidized bed boilers. By using an oxygen-carrying mineral as bed material, Improbed™, the oxygen distribution in the boiler is significantly improved.

The use of Improbed™ delivers several benefits to fluidized bed boiler operations, related to improved oxygen distribution and resistance to agglomeration and sintering.

ADVANTAGES


advantages_01.png

Increased boiler capacity and efficiency

The surplus of air in the furnace can be reduced. This allows a higher boiler load with increased heat and power production, as well as increased efficiency.

advantages_02.png

increased bed material efficiency

The Improbed™ agglomeration and sintering resistance in combination with its magnetic susceptibility significantly reduces bed material consumption and thereby ash flows.

advantages_04.png

No risk for agglomeration or sintering

By capturing alkali inside the Improbed™ particles agglomeration is prevented. A high melting temperature excludes the risk of sintering.

advantages_03.png

Reduced operating and maintenance cost

The superior oxygen distribution and alkali absorption capability of Improbed™ leads to less fouling and corrosion.

 

SOLUTIONS


 

Customer commitment

The Improbed™ concept is based on a close partnership between our customers and us where risks and results are shared. 

Our comprehensive methodology is applied for evaluating the customer’s technical and financial potentials and risks. Implementation, optimization and performance monitoring is done in cooperation with the customer.

The partnership serves as a warranty of our commitment: the concept is only profitable for Improbed when it delivers value to the customer. It also allows an attractive business model with no major upfront costs.

Waste to Energy

The Improbed™ concept enables significant benefits for a typical waste combustion plant. Tests conducted at a customer’s waste combustion plant indicate the potential to increase boiler capacity by 5-10%. Another important value is a significant reduction of bed material turnover. Until now up to 90% reduction has been achieved.

Biomass to Energy

Biomass combustion plants also benefit from an increased boiler capacity and a reduced bed material turnover. In addition, further benefits can be obtained as use of more corrosive fuel mixes is enabled.

RESEARCH


 
 

The Improbed™ concept is the result of the long-term research cooperation between E.ON and Chalmers University of Technology. Since 2013 the knowledge and IP development has been an important part of the business development project that led to the foundation of the Improbed company in 2015. 

The research competence and capability of E.ON and Chalmers University of Technology have provided the Improbed™ concept with a solid scientific foundation and an extensive patent portfolio. Both are constantly developed, as more optimization and adaptation opportunities arise. Current research programs are co-funded by the Swedish Energy Agency.
