As a part of the reconstruction of the K11 boiler in the Mondi Štětí paper mill, a complete replacement and modernization of the internal fuel transport was carried out. The fuel routes are divided into two separate coal routes with a capacity of 50 t/hour and one bio fuel route with a capacity of 84 t/hour.
The bio fuel route consists of these components:
- Biomass chain conveyor with a length of 20 m with a maximum capacity – 84 t/hour. Stainless steel design
- Screw conveyor 1 000 mm in width with 2 screws – all in stainless steel design
- Silo – movable bottom incl. hydraulic units – so-called Push-Floor (during a shutdown after 3 years of operation replacement for stainless steel design took place)
- Continuous weighing with flow scale
- Sealing air system and continuous extraction of the conveyor space to ensure the under-pressure
- Rotary feeders, motorized slide gates
Coal routes consist of these components:
- Chain conveyors with a total length of 69 m. Maximum capacity 50 t/hour
- Continuous weighing with flow scales
- Rotary feeders
- Sealing air system and continuous extraction of the conveyor space to ensure the underpressure
