Kraftblock's Waste Heat Recycling System.

Improve energy efficiency in heavy industries.

Kraftblock's Waste Heat Recovery System utilizes excess heat from industrial processes ranging from 350°C to 1,300°C. Waste heat that would have been released unused into the atmosphere is reused in the same or another process, reducing the amount of fossil fuel needed.

How it works


Capturing Waste Heat

The chimney or excess system is tapped and the waste heat recovered usually before cleaning or cooling it down.



The flue gas is guided through the storage, and the material absorbs the heat.



The green heat can be used at a later point in the same or in another process to reduce or replace fossil fuels.

Reduce your fuel costs with Kraftblock


Waste heat can be recovered and used with Kraftblock. This is a way to optimize the overall energy efficiency of process and thus to reduce your operating costs by saving on fuel consumption. In a kiln, between 40% and 60% of the energy is wasted. Reusing it in the same or another process saves fuel. By reducing the amount of fossil fuel needed, you also avoid emissions and therefore the cost of emissions such as EUA or other carbon taxes.
