Industrial Boiler

Magno VR
250–550 kW

Forward grate firing technology
driven by hydraulic drive

  • Professional & qualified planning
  • Robust industrial design
  • Solid radiation vault
  • Recycles fuels up to 60% of water content
  • For wood chips up to M60/W60

High performance industrial boiler

Industrial heating for intensive heat demand

Step grate boiler technology is used wherever wood chips, fine wood shavings and bark with high residual water content or other biomass fuels are used. The Magno-VR 250–600 models have an integrated forward flat bed step grate.  Steady combustion on the forward grate ensures the lowest possible emission levels in the exhaust gas. Automatic de-ash occurs at the end of the grate.

Benefits:
