Wood-chips/pellets boiler BURNiT CB

Steel Combined boiler satisfy the heating demands of large sized spaces as public and industrial buildings. Boiler СВ 160kW is easy to transport and installation even its impressive size. Intelligent controller. Lambda control. Direct connection to closed or open loop heating system.
Ecological and highly-efficient combined boiler designed for firing wood-chips/ pellets.
As an alternative fuels can be used: agri-pellets or dry fruit pits (cherries, plums, olives, crushed nut shells of apricots and ect.).

Tested and approved according to EN 303-5, class 5.


Maximum operating pressure of 3 bar
Automated cleaning of the boiler
Intelligent controller
STB thermostat
Built in discharge mechanism

Product Features:

  • Maximum operating pressure of 3 bar.
  • Capable to feed a large-scale heating system.
  • Intelligent controller controls central heating pump, DHW (domestic hot water) pump for and buffer tank.
  • Lambda control for efficient combustion process.
  • Ceramic side panels which supply an additional quantity of air and also isolating the burner, assist the combustion process.
  • Burner is connected laterally of the boiler. The burner has a mechanical moving grates and so can use different fuel types (wood-chips, pits, wood-pellets, agri-pellets).
  • Automated cleaning of the boiler.
  • Mechanical cleaning of the burner.
  • Convenient inspection door.
  • Chimney with an option for 45 degree rotation – 5 positions for convenient connection.
  • Built in discharge mechanism drives the ash and soot into a rolling container.

Available sizes, kW:

  • 160

Safety devices

  • STB thermostat.
  • Thermostatic protection (80°С).
  • Safety thermostatic valve (95°C).
  • Fuse 16A.
  • Phase Monitoring Relay.
  • In case of power interruption, all parameter settings are stored in the memory of the controller.

For burning of wood-chips or fruit pits and crushed nut shells (as an alternative fuel) a modular auger mechanism must be installed to the CB boiler.
This modular auger mechanism is with length 5m, and fuel mixing system with diameter up to 4m.
For burning of wood-pellets or agri-pellets (as an alternative fuel) an auger for pellets must be installed to the CB boiler.
