Latest Patents
One of Scheffler's latest patents is a plasma burner for transferred electric arc. This plasma burner features an annular passage that extends along an insulated tube, which defines the outer wall of the electrode lance. The design is strategically located between the electrode lance and the multi-wall burner shell to deliver auxiliary gas outwardly of the plasma gas. The nozzle forming end of the electrode lance includes a coolant circulation, as does the burner shell. This construction effectively avoids the formation of parasitic arcs, enhancing the efficiency of the burner.
Another significant patent is a process for the biological treatment of waste water. This method involves the biological aerobic purification of waste waters, maintaining a temperature range of 30 to 60 degrees Celsius in the first process stage and 20 to 40 degrees Celsius in the second process stage. The temperature in the first stage is always higher than in the second stage. A portion of the activated sludge from the second stage is returned to the first stage, resulting in a high decomposition output and producing activated sludge with excellent sedimentation behavior.
