iRecu®

With hydrogen and maximum efficiency in the direction of CO₂ neutrality.

Our best-in-class

Up to 50% fuel savings

With the iRecu® to the energy turnaround in the industry. Efficient heat recovery through optimum preheating of the combustion air. Suitable for hybrid plant operation with hydrogen and natural gas.

Patented dual-fuel mixing unit: Optional operation with 100% hydrogen, 100% natural gas and any mixture of the fuel gases

TPMS structures: Can only be produced in 3D printing, difficult to master, but they deliver unbeatable efficiencies

Custom made in series: 3D printing enables the 1:1 replacement of existing burner systems, the available installation space can be used optimally

Cold exhaust gas: The energy in the exhaust gas is lost. We reduce the exhaust gas temperature to up to 200°C - take a measurement at your plant...

Three steps to CO₂ neutrality

Efficiency increase

Step 1 - No green hydrogen available. With the iRecu® up to 50% savings in fuel and CO₂.

Hybrid operation

Step 2 - Little green hydrogen available. iRecu® enables alternating production of CO₂-neutral and classically manufactured products.

Decarbonization

Step 3 - Sufficient green hydrogen available. 100% CO₂-free production without renewed plant conversion.

Save energy

Compared to conventional recuperative burners, high efficiency of the iRecu® can generate additional energy savings of up to 15%, and up to 50% compared to cold air burners.

Save CO₂

With our iRecu® you can already make significant CO₂ savings today. Through high efficiency, you are already taking the first step towards a sufficient supply of green hydrogen.

Save money

Thanks to the high efficiency of the iRecu® , you not only save CO₂, but also money. In addition, you save investment costs, as existing plants have to be optimized and not renewed.

Plant optimization

Existing plant systems can be optimized with the help of the iRecu® so that only the existing burners need to be replaced. Our iRecu® is designed specifically for your plant.

Award winning technology

Take the chance to make the energy transition a reality together with our products and feel free to advertise e.g. with the IKU (here) or the Efficiency Award NRW (here).

Innovative idea

Our iRecu® combines thanks to 3D printing the strengths in the form of efficiency, emission control and hybrid drive in one product.

iRecu® – Fuel Flexible

The Dual-Fuel Recuperative Burner

The combination of additively manufactured mixing unit and additively manufactured recuperative burner offers you maximum fuel flexibility at your thermoprocessing plant. Other fuels such as coke oven gas or propane/butane can also be used.

Dual-Fuel Mixing Unit

By using different fuel channels in the dual-fuel mixing unit, it has been possible to burn both natural gas and hydrogen reliably in the plant. In order to cope with the different fuel properties and to comply with statutory emission limits, the combustion areas are designed for the respective fuel gas.

Recuperative Burner

The innovative structure of our recuperator enables highly efficient heat transfer with low pressure losses thanks to optimized flow guidance. The structure used is a complex triple-periodic minimum surface, or: TPMS.

Award Winning

The iRecu® speaks for itself with its unique strengths. Here is What the juries say about our iRecu®.

The new mixing unit for gas burners efficiently and sustainably reduces energy consumption and nitrogen oxide emissions and is very easy to handle. In addition, the product has been made possible by applying a new manufacturing technique: 3D printing ensures that the mixing units can be produced precisely and easily.

The additively manufactured recuperative burner from Kueppers Solutions GmbH is impressive on two counts. On the one hand, its shape allows the exhaust gas heat to be used at a higher temperature level, and on the other hand, it was manufactured using an innovative 3D printing process. It reduces both the fuel requirement and the emissions of industrial thermoprocessing plants - it doesn't get any better than that.

Kueppers Solutions GmbH (Gelsenkirchen, Germany) built with the iRecu® the world's first 3D-printed series burner with optimized heat recovery. Even before the availability of green fuels, this can save 2.2 million tons of CO₂ in industrial thermoprocessing plants, and in the next step with green hydrogen via the dual-channel gas mixing unit, a further 13 million tons per year.

FAQ

We have the answers to your questions! In case there is anything else you would like to know, please do not hesitate to contact us anytime.Contact us

What is iRecu® and how does it work?

iRecu® is the recuperative burner developed by Kueppers Solutions, which highly efficiently transfers the residual heat contained in the exhaust gas in counterflow to the verbena power and achieves best efficiencies due to its innovative geometry, measured by relative air preheating.

How is the iRecu® manufactured?

Almost all parts of the iRecu® are manufactured in so-called additive manufacturing processes, using 3D printing. We use a wide variety of 3D printing processes: SLM, WAAM as well as a modified binder jetting process, to name just a few.

Do I need to replace my entire system and is the iRecu® suitable for my system/processes?

No. Our iRecu® is developed and designed specifically for each plant. The aim is to optimize existing plants and thus minimize investment costs. In addition, the iRecu® custom ``made in Germany`` is developed individually for your plant. At present, we can reach operating temperatures of up to 1100°C with our iRecu®. Basically, the iRecu® is suitable for all thermoprocessing plants.
