Underfeed Firing NRF

Brief description
  • Automatic Underfeed Firing NRF
    Boiler capacity from 250 up to 835 kW
Fuel
  • Wood shavings
  • Wood chips
  • Pellets
  • Chip briquettes
Advantages
  • Optimum use of combustion energy by the vertical heating surfaces of the four-pass technique
  • Guaranteed undercutting of the limiting values corresponding to 1. BlmSchV, even in the partial-load range
  • Suitable for low room heights and confined installation conditions
  • Lateral cleaning in working height (due to the vertical heating surface almost no ash remains; the cleaning intervals are very long)
  • Connection for fossil fuels possible
  • Very low-maintenance and easy to service
