Automatic De-ashing Assembly with Ash Container
Description
De-ashing in Ash Bin, 63.5 USG (240 L)
De-ashing in Ash Bin, 211.3 USG (800 L)
Complete auger de-ashing from the ash chamber for the
fire block into an externally situated movable galvanized
ash bin. A light barrier control system keeps the level of
the ashes constantly over the auger.
As a result, the ash in the ash pan under the incineration
system can burn out, and in normal operation only cool
ash that has burned out is conveyed into the container.
