Example of Gasifying Boiler for Wood            The boiler consists of two chambers, one placed upon the other. The upper chamber makes up the fuel container, and the lower one, combustion chamber and ash collector. Between the two chambers, a new, rotating, patent protected grate is placed. The grate ensures perfect combustion of coal, wood, or a combination thereof, as well as simple cleaning.






                   

  • Coal and wood separately, we recommend together.
  • Revolving furnace grate - easy for ash removal.
  • Fan controlled - pressure (S).
  • Simple handling & cleaning.
  • Large fuel container.
  • Boiler contains no tubing - simple cleaning (Except C 50 S).
  • Secondary air is pre-heated to high temperatures.
  • Small size and low weight.
  • High quality.

The exhaust fan, when compared with a pressure fan, exhausts combustion products
and minimises smoke during stoking and boiler operation.


The settings of the grate segments is displayed on the picture, and the same for use of coal or wood.

The secondary air supply channel and the flat part of gasifying grate must always point downwards.
