Example of Gasifying Boiler for Wood           The boilers are constructed for burning wood on the principle of gasification with the use of a gas exhaust ventilator. The exhaust ventilator withdraws the combustion gases from the boiler and draws primary and secondary combustion air into the boiler.

          The boiler body is produced from 3-8 mm welded steel. They comprise the upper fuel hopper, which is equipped at the bottom with a heatproof longitudinal nozzle where the preheated secondary air is introduced for re-burn of the gases. The lower burnout chamber of the multiple chamber furnace is equipped with a heatproof ceramic for total combustion and effective heat transfer. There is a vertical combustion gas duct in the back of the boiler body is equipped with a valve for ventilating during loading and drafting for start up. The upper part of the combustion gas duct is fitted with a flue gas outlet for connection to a chimney.



  • Option to burn large pieces of wood.
  • Primary and secondary air is also preheated to a high temperature - higher efficiency
  • The ventilator automatically switches off when the fuel burns out.
  • Easy servicing and cleaning.
  • Large fuel container.
  • Large space for ash (we clear it out once a week with wood)
  • Boiler without tube plate - easier cleaning
  • Small size and low weight
  • High quality.
