ash auger rotates slowly to transport ash out of the combustor
stoker assembly, and into a covered ash bin. Both the rotating
ash ring and the ash auger are driven by the same variable-
speed electric motor and reduction gear assembly.
Ash Bin: A covered ash bin, located out-side of and adjacent to the
stoker assembly, serves to receive the ash from the ash auger.
The ash bin cover is removable, and the ash bin is detachable
and removable from the ash auger assembly. The ash bin is
manually emptied when 75% full of ash.
Hydronic Boiler Ash Clean-out Doors: The hydronic boiler is equipped
with three lower exhaust plenum ash clean-out doors, and four upper
ash clean-out panels to access boiler tubes. The lower ash clean-out
doors are insulated, hinged, and latched assemblies that permit removal
of fly ash that has accumulated in the boiler exhaust gas plenum. Four
insulated and clamped removable upper ash clean-out / boiler tube
access panels are situated on top of the boiler. The four upper panels
permit removal of fly ash that has accumulated in the upper boiler
exhaust gas reversal plenum, as well as provide access to the heat
exchanger tubes and removable fire-tube turbulators for cleaning during
routine maintenance.
Stoker Clean-out Doors: The stoker unit is equipped with two hinged,
latched and insulated clean-out doors that permit removal of fly ash that
has accumulated in the stoker unit. Ash removal from this region is
performed infrequently during routine maintenance.
Removable Stoker Grate: The slotted ring-shaped stoker grate is built
as four removable circular segments, so that any fine mineral or sand
particles present in the fuel that have fallen into the primary combustion
air chamber beneath the stoker grate can be cleaned out during routine
maintenance.
Stoker Grate Access Panel: The stoker grate assembly is fitted with a
bolted and removable ash clean-out access panel, which is removed for
ash clean-out access during routine maintenance.
Particulate Cyclone: Coupled to the boiler is a high efficiency
particulate cyclone dust collector designed to remove fly ash from the
