High-performance industrial boiler

Designed for permanent high-performance operation

With the Magno industrial systems up to 2,500 kW output, we offer an extensive range of products. The step grate boiler technology (SR) is used wherever wood chips, fine wood shavings and bark with high residual water content or other biogenic fuels are used. A forward grate step grate is used for the Magno-SR 800–2,500 models.  Automatic de-ash occurs at the end of the grate. This ensures less service on the boiler and thus saves money. The target groups for these industrial boilers range from hotels, restaurants, but also district heating schemes and large commercial to industrial enterprises. Modulating operation and highest efficiency up to 93% are possible.

  • Step grate firing (SR) for drying, gasification and fuel combustion
  • Automatic de-ash at end of grate
  • Grate carriage with maintenance-free sliding guides
  • Step grate technology driven by hydraulic drive
  • Dual-walled steel housing design to preheat the combustion air
  • Combustion control via flue gas temp. sensor, combustion chamber temp. sensor, boiler temp. sensor and Lambda sensor
  • Radiation vault with high-temperature resistant refractory bricks
  • Double-hinged combustion chamber door in front wall of combustion chamber
  • Cleaning and service door below grate
  • Dynamic combustion air control by air dampers and air flow sensors
  • Automatic, pneumatic heat exchanger cleaning
  • Suitable for wood chips EN, ISO17225-4 to P45S up to M60/W60
  • Recycles fuels up to 60% of water content
  • Safety heat exchanger (optional)
  • Under grate de-ash by means of hydraulic drive
  • Central de-ash (optional)
  • Exhaust gas recirculation (optional)
