50 kWtherm dust firing test plant
Plant Features
- test facility with an indirect firing system for pulverized fuels
- cylindrical combustion chamber with a roof burner, consisting of five single segments with an inner refractory lining and air-cooled walls
- operations: conventional combustion with air/combustion with pure oxygen ("oxyfuel")
- flue gas circulation for ensuring realistic oxyfuel conditions at combustion
- pneumatic fuel transfers to the burner with air or circulating flue gas
- different types of burners available (stream burner, swirl burner); burner optimization with CFD
- additional gas burner for ignition firing or for combustion support
- good accessibility for flame observations with standard probes through numerous measuring ports
- modern facility control system with graphic user interface and constant capture of measure data and flue gas composition
- options for additional additives like Ash, SO2, H2O, HgCl2
- flue gas measurement of (Hg, O2, CO2, H2O, NO, NO2, N2O, SO2, NH3, HCl)
- possible combination with pilot plant for flue gas desulphurization
