Your advantages

  • Revised combustion chamber geometry and masonry quality for very low emission values and optimum burnout over the entire output range with varying fuel.
  • New heat exchanger with high transfer surface for low exhaust gas temperatures and maximum efficiency. Optionally equipped with bypass for maximum filter availability.
  • Exhaust gas recirculation primary and secondary with homogeneous premixing before injection for dry fuels.
  • Preheating of the combustion air by suction via the boiler cladding, thus lower heat radiation via the boiler cladding
  • Newly developed grate door locking system with electromechanical safety cut-in. With O2 monitoring of the combustion chamber. Optionally with camera for optimum monitoring.
  • Further developed control software to guarantee low emissions even in low-load operation with start/stop behavior.
  • Operation optimization through plant monitoring with remote access.
