Fluidised bed combustion technology
Flexible firing system for different fuel properties with control system for optimum firing power
- Fluidising-gas as a mixture of primary air and recycle gas
- Two controlled secondary air levels with recycle gas
- The temperature is controlled throughout the combustion chamber
- No unprotected areas of metal in the combustion chamber
Optimized fuel and bed material system for biomass and waste material
- Dispensing system for fuel with less than 300 mm edge length
- Pneumatic fuel feeding
- Open nozzle floor able to exhaust coarse particles up to 300 mm length
- Coarse particles are screened via the bed ash system
Metering screw with shaking apparatus
- Dipenser for fuel with up to 300 mm edge length
- Precise regular dosage
- Pneumatic fuel flow
- Backfire protection via surveillance of temperature and exhaust volume flow
- Open backfire valve when normal operation
Open nozzle grate
- Open nozzle grate able to exhaust coarse particles up to 300 mm length
- Flat swirl bags
- Low pressure loss
- Regular distribution of the fluidising gas
Pendulumn discharge
- Mechanical bed material discharge
- Optical classification of bed material
- Continuous sand return into the combustion chamber
