Implementation of the new technology on site
Once the retrofit plan and all the new components have been approved, they are made in the main Benninghoven factory and transported to the job site. The customer’s plant staff and Benninghoven service technicians often form a team, as was the case in the Mintraching retrofit project. “And it works so well!” says Thorsten Neidhöfer, one of the Benninghoven fitters on site.
New higher-performance EVO JET 3 triple-fuel burner
Modern Benninghoven technology was integrated in the existing asphalt mixing plant which will allow the plant to operate in an economical and environmentally friendly way for years. The heart of this equipment is made up of the burner and the dryer drum. With oil, liquid gas and coal dust, the new EVO JET 3 burner can now fire three fuels instead of two, which will make Guggenberger more independent of fluctuating energy costs in future. A new coal dust dosing system has been fitted for this fuel; its overhauled design will bring key benefits for Guggenberger in terms of functionality, safety and fuel consumption. What is more, the burner is designed for higher performance and thus contributes to increasing plant performance as a whole. Drying performance increases significantly, especially in the production of mixes such as stone mastic and mastic asphalts which are made entirely from white mineral – in numerical terms, performance increases from 140 t/h to 190 t/h.
