Fuel In-Feed Conveyor (By Customer); Fuel In-Feed System - Max-Ox MX-900B Operator's Manual

Fuel In-Feed System Conveyor ( by Customer):
You will need to provide wood chip fuel in-feed conveyor system in
order to supply fuel to your MX-900B unit. Your fuel in-feed system
should be tailored to your specific site layout requirements.
We recommend that your fuel storage bin or silo be designed to
protect your wood chips from the weather. Your wood chip transfer
conveyor should be designed to transport fuel from your storage
bin/silo to the MX-900B Fuel Metering Bin.
1. Sizing your Transfer Conveyor: Your transfer conveyor system
should be sized to convey approximately _ to 1 cubic yards of
wood chips per hour in order to support the maximum fuel
firing rate of the Max-Ox unit. This fuel flow rate criteria is a
conservative estimate that takes into account the additional fuel
volume flow needed when firing green (fresh-cut) hardwood
wood chips, as well as the variations in bulk density (fluffiness)
of the chipped or shredded wood fuel types available. Of
course, the dryer your fuel is, the less of it you will need to burn
to achieve the full power rating of renewable fuel combustion
units.

Fuel In-Feed System:

Your MX-900B mechanical hardware begins at the fuel in-feed
system. The fuel in-feed system serves to automatically receive wood
chips from your fuel storage and transfer system, and then deliver
them to the stoker grate combustion unit. The fuel in-feed system
consists of an inlet chute, an air operated knife gate, a small auxiliary
electric air compressor, a small storage chamber called the metering
bin, a fuel in-feed auger with variable speed drive motor, and a set of
automatically controlled electrical contacts to energize your fuel in-
feed conveyor motor controller.
Inlet Chute, Knife Gate, Metering Bin, and Air Compressor:
The fuel in-feed system inlet chute serves to funnel wood chips
through an open knife gate, and into the metering bin. A level sensor
in the metering bin signals your fuel transfer conveyor to stop, and
