Applications

The ongoing work aimes at appliances such as fireplaces, stoves or ovens. For this kind of appliances several prototypes are or have been in operation. Based on the experiences with from those test runs the, development of the partcile separator form small wood fired furnaces will be carried on. It is intended to be ready for series productions within the next one or two years.
From here on, the following applications are under consideration:

small wood fired furnaces: open or closed fireplaces, stoves, ovens, pellet fired boilers, wood log fired boilers

So far the development focussed on applications such as fireplaces, stoves or ovens. Images of an example installation in a modern fireplace are shown here .
Many investigations have been performed with a pellet fired boiler. Furthermore a field test over several weeks has been performed with log wood fired boiler.
 

small automatic appliances

Since small automatically fed wood furnaces offer another important field of applications, it is intended to extend the development in order to adapt the concept for these furnaces. For this purpose a first prototype has been designed which has been operated at an understoker furnace of about 100kW heat output.
 

problematic appliances

With the increased use of fuel wood, there is, unfortunately, a tendency toward more complaints within neighbourhoods. In such problematic situations, the retro-fitting of an exhaust gas aftertreatment system like the MiniPab may help to reduce the emissions to a level that eliminates the cause of the complaints. Chances of success and the actual procedure for retro-fitting have to be determined for the specific case.

.

prerequisites for successful applications of the Minipab:

  • metal flue pipe, diameter 130mm to 250mm
  • Accesibility
  • low flue gas velocity
  • typical flue gas temperature below 500°C
  • Negative pressure within the flue pipe
  • MiniPab: Miniature Particle Absorber for small wood fired furnaces
