With the Benninghoven hot gas generator, operators of asphalt mixing plants can achieve maximum RAP feed rates of 100% and simultaneously fulfil strict emission threshold requirements.
The hot gas generator has become an established technology in asphalt production from RAP. This solution developed by Benninghoven is already being used successfully in numerous asphalt mixing plants. Benninghoven is now presenting it at Bauma 2022.
The Benninghoven hot gas generator is the solution when maximum RAP feed rates and reduced operational emissions are the target in the asphalt production process. The Benninghoven technology – which can also be integrated in existing plants as a Retrofit solution – makes it possible to produce asphalt mixes from 100% reclaimed asphalt pavement material (RAP). All of this is made possible by gentle heating with hot gas using the counterflow principle, As a result, the asphalt mixing plant offers a legally compliant solution for meeting the statutory emission limits set out in the TA-Luft, Germany’s central technical regulation for controlling air pollution from industrial and agricultural installations. This legislation requires a significant reduction in operational emissions. The total carbon emissions (Ctot) generated by a process may not exceed the threshold limit of <50 mg per cubic metre of air. This is guaranteed by Benninghoven.
