What is a slot furnace?

Slot furnace is a new generation furnace, where the air needed for combustion is directed to the hearth through slots in the back of the wall and on the sides of the hearth. This type of distribution of air in the hearth ensures the mixing or turbulence of the gases released from the wood during combustion. This ensures a significantly cleaner combustion process under a higher temperature and with the amount of energy obtained from the wood being significantly higher. This also results in a significantly higher efficiency of a hearth of this type.

To achieve even better combustion, the furnace blocks are made of a special material with excellent heat storage properties and sufficient insulation properties to ensure a rapid increase in the combustion temperature of the furnace. The relative density of the material is 2000 kg/m3. Additionally, a material with a high temperature resistance (1260°C) is used in the ceiling of the furnace, i.e. a mirror on the ceiling of the furnace with a relative density of 300 kg/m3. This material ensures a rapid rise in the temperature of the hearth and “reflects” heat back to the furnace; thus it creates a high combustion temperature.

This oven has been completed as a collaboration:

  • “Ecokolle” developed by OÜ Tuli ja Suits
  • Tested with researchers of the laboratory boiler of the Estonian University of Life Sciences
  • Tested at the Environmental Research Centre
