Automatic ash removal cleans the boiler ashtray and the area around it using a screw feeder, which stuffs all the ash fallen into the ashtray part of the boiler into a special container. After filling, simply disconnect the external container from the boiler and empty it. This greatly simplifies the boiler operator's work.

The frequency of external container cleaning depends on the boiler output, but ranges from 1 month to once every six months. 

Automatic ash removal significantly extends the intervals required for manual cleaning.
