Salt River Project
Springerville Generating Station (Unit 4)



Engineering, procurement, expediting, and field technical assistance of the coal handling system expansion. The conveying system is designed to receive rail delivered PRB coal. New chute work was designed to tie into the existing transfer tower to feed the new transfer tower for Unit 4 coal handling. The coal is transferred on dual 3,000 TPH conveyors to dual radial stacker-reclaimers. The coal is crushed with two 750 TPH double roll crushers from 4-inch to ¾-inch before being transferred to the expansion of the existing Unit 3 crusher tower which feeds coal to Unit 3 and new Unit 4 coal silos. Seven of the conveyors are enclosed in 3,300 feet of tubular gallery. The coal handling system expansion includes dust collection for all new transfer points, dust suppression for the coal pile, and conveyor gallery ventilation.
