A major southern utility required a system for reclaiming stored coal including western sub-bituminous. Various grades of coal were then to be blended at specified rates to satisfy boiler demand and air quality regulations.
The Carman Solution:
Telescoping chutes control dust while distributing graded coal over fourteen (14) Carman Drawdown Hoppers strategically located to maximize reclaim. Self-contained adjustable rate vibrating feeders under each drawdown maintain blend specifications while satisfying boiler fuel requirements.
