13.10 Ash auger.
The XXL boiler have automatic ash auger in the boiler and a tilted ash auger on the side, to transport the
ash into a suitable ash container.
It is important that the connection from the tilted ash auger to the ash container is closed tight for 3
reasons:
1.
We do not want dust in the boiler room
2.
If it is not closed tightly the boiler controller will get false O2 readings
3.
The flue fan have to run quicker, to keep the correct under pressure in the boiler.
Adjustments of the ash auger are done as described in chapter 7.6.2.
It is important that the bottom ash screw is filled / covered with ash. If not the is a risks of:
1.
The boiler gets false air inside.
2.
There is transported glowing ash into the ash bin.
3.
The ash auger is exposed to unnecessary heat.
On this picture you can see the ash auger in the
bottom of the boiler. You also can see the front of the
fire grate which pushes the ash down to the ash auger.
It is also possible to let the horizontal ash screw out
the wall.
The lifting auger can be mounted like on this picture
with the ash bin.
