San Jose Power Station
Coal Handling System
Puerto Quetzel, Guatemala

Roberts & Schaefer was selected to design and supply a new coal handling system at the San Jose Power Station in Guatemala City, Guatemala.

The new coal unloading, coal silo filling system, and storage system starts with a self-unloading ship fed hopper that uses a variable speed belt feeder to feed an 850-foot long 2,200 tph, 60-inch wide overland conveyor. The overland conveyor transports the coal to a radial stacker, which creates a 50,000-ton storage pile for station use and a second 40,000-ton storage pile to hold coal for resale.

The new coal silo filling system starts with a front end loader fed reclaim hopper with variable speed belt feeder feeding an 800-foot long, 220 tph, 24-inch wide belt conveyor. The belt conveyor then feeds a drag chain conveyor above the three coal silos that are equipped with discharge gates used to fill the silos.
