Germany is the largest steel producer in the EU and the seventh largest steel producer in the world. Around 43 million tonnes of crude steel (2014) are produced annually.

In the production processes there is a lot of steam. For example, in the low-pressure range, a pressure drop of 0.6 bar can be applied to our technology and increase your energy efficiency. The typical application of the ENVA energy module is a pressure reducing valve. At this point, the energy module is switched as a bypass and performs the required steam pressure reduction while it generates electrical energy.

By connecting the Energy Module as a bypass, your existing process is not affected in the event of a fault. The patented ENVA process is based on the use of a rotary lobe blower as an expander, which can, with its compact and robust design, handle a wide range of steam qualities. A rotary lobe blower is extremely robust compared to a turbine.

We already have a reference plant in the coking plant Prosper / ArcelorMittal, which you can look at if necessary.

Depending on the application, an amortization period of less than 3 years is generally the rule. By applying our technology, you may also be entitled to the energy tax reimbursements, or energy efficiency grants which can make the economics even more attractive.
