8.1 Description of de-ashing system
The de-ashing system compresses the ash and conveys it from the ash chamber into the ash box. The ash box enables
the ash to be easily disposed off without creating dust.
1 Turnstile with agitator, door plate and mounting
bolts 5
Ash container
2 Ash box with single-hand lever 6 Sub-assembly with extractor auger and cable
3 Mounting frame 7 Extended nuts to secure the sub-assembly
4 Cable duct with mounting bolts 8 1 pack of bio-bags
Note:
All components for the de-ashing system are packaged in a separate box which is shipped together with the
boiler. Open the box and check that all parts are available before starting work.
8.2 How the de-ashing system works
The de-ashing system is fully automatic. A dedicated motor in the sub-assembly of the de-ashing system drives the
de-ashing auger. Its function is controlled and tested by the boiler controller.
The motor in the sub-assembly of the de-ashing system drives the de-ashing auger and the turnstile agitator arm. The
agitator arm conveys the ash to the de-ashing auger. The de-ashing auger conveys the ash from the ash chamber into
the ash box.
When the ashbox is full then the alarm text
"Ash" appears on the display of the boiler controller. If you do not empty the
ash box, the completes a futher 3 de-ashing sequences before failing. The boiler controller then displays the alarm
text
"Ash box full" . The heating system switches off. The heating system switches back on again automatically after
the ash box has been emptied.
For pellets with a very high ash content, it is necessary to extend the duration of the de-ashing process and possibly also
reduce the time interval between de-ashing processes. This can be done using parameters P195 and P196.
