April Solutions 2015 ASGCO® Helps Northeastern US Coal Burning Power Station Improve Material Flow and Reduce Maintenance Costs

Constant abrasion from high moisture bituminous coal was causing serious wear and plugging on flow chutes at a major Northeastern US coal burning power station.  ASGCO® 3-DEM® Designed Flo-Control® Chutes are custom tailored to adapt to unique challenges of any material in any environment.

A major US coal burning power plant was experiencing constant chute plugging after recent
upgrades to its coal yard.  These issues were compounded by spillage due to holes being
formed almost immediately in the new round chutes that were installed.  These problems
led to major maintenance down time, and the round design of the newly installed chutes
proved difficult to repair.  This situation prevented the silos from being stocked with coal,
reducing productivity, as well as adding a significant cost for repair and maintenance from
holes in the new chute after 30 days of service.  Because of the round design of the chutes,
repairing the holes and replacing the liners became cost and time prohibitive.


After surveying the loading system, ASGCO® technicians recommended a 3-DEM® Chute
Analysis program to redesign the failing chute sections.  This cutting-edge simulation
identifies the optimal design for full capacity flow under all conditions with no build up or
plugging while also decreasing the wear on the internal liners. ASGCO® also recommended
an advanced liner system that would allow for easy maintenance and minimal stocking
requirements for liner plate replacement.

The redesigned ASGCO® Flo-Control® chutes completely eliminated the plugging and
buildup and allowed for increased tonnage flows even with high moisture, low quality coal.
