Case Study - Retrofit project waste incineration: Optimization of e-filter discharge
Loibl renews E-filter residue discharge for thermal waste recycling plant in Mannheim using customized conveyor technologyLocation
Planning Period
January 2024 – October 2025
Special Features
Heated conveying system, state-of-the-art measuring technology, particularly wear-resistant pneumatics with weighing and short assembly time during system revision phase
Mannheim. To optimize the e-filter residue discharge in the Mannheim waste incineration plant, Loibl is supplying the entire conveyor technology, including insulation between the filter system and the residue silo. The trace heating system heats the conveyor system to a holding temperature of 140 °C. As water is bound in the ash, the high temperatures are intended to prevent it from condensing and leading to caking and bridging.
The conveyor system consists of two lines. These include six discharge hoppers, which discharge the ash mixture from the filter system onto three transverse trough chain conveyors, followed by rotary valves, which ensure the air seal to the filter. A collecting trough chain conveyor with emergency discharge and a crusher, which crushes and processes the ash for the pneumatic conveyor system, are connected. A further trough chain conveyor is connected to the crusher. This transfers the material to the storage container of the pneumatic conveying system. With the help of the heated pneumatic system with weighing, the ash is conveyed to the residue silo. The new conveyor technology from Loibl replaces the old, failure-prone screw discharge system.
The new pneumatic conveyor line is equipped with wear-resistant basalt pipe bends. This is equipped with wear monitoring, which draws attention to timely replacement. In line with the modernization measures, the outdated silo top filter and the vacuum and overpressure flaps on the residual material silo will be replaced with suitable components. Due to the more powerful pneumatics, a filter with a larger filter surface is required.
The entire conveyor system is equipped with modern fill level and temperature sensors, which automate the monitoring process and ensure smooth operation.
The installation of the new conveyor technology will take place during the inspection phase of the 2025 waste incineration plant. Our experienced installation team will install the new conveyor system during a short installation period. Thanks to decades of experience, the team is ideally prepared for this challenge.
The installation of the new system will help to increase the efficiency of the plant and enable sustainable operation.
