Thermal behavior of Refused-Derived Fuel in stationary fluidized bed combustion (VERENA)

Fluidized bed plant for tests of thermal waste treatment

in german: VERENA (VERsuchsanlage zur ENergetischen Nutzung von Abfällen)

With the kind support of ThyssenKrupp AG, the construction of a fluidized bed pilot plant was completed in 2006. The official inauguration of the plant took place on 18.07.2007. The full commissioning took place in 2008.

Analysis parameters:

•     Flue gas analyzer for H₂O, O₂, CO₂, CO, N₂O, NO, SO₂, HCl, HF, NH₃, Corg.
•     flue gas analyzer for O₂, CO₂
•     various measurements for T, p, flow rate

Plant key figures:

•     Thermal capacity: approx. 330 kW
•     throughput capacity: 50 - 500 kg/h
•     flue gas volume flow: 300 - 1,200 Nm³/h
•     Nozzle floor diameter: 600 mm
•     Nozzle floor area: 0.28 m²
•     Reactor height: 6,500 mm
•     Reactor diameter: 800 mm
