Project Description
Tri-State's Nucla Station was experiencing boiler tube wear due to an excessive amount of rock being mined with a local source of coal.  To alleviate this problem, Tri-State approved the addition of a rotary breaker to both crush the coal in its secondary stage and separate rock from the fuel.  Tri-State engaged Energy Associates to support their efforts on this project.

Energy Associates was responsible for the detail design engineering for the mechanical, structural steel, electrical, and I&C portions of the project.  In addition, Energy Associates provided foundation loads to assist Tri-State in engineering the foundations.

Breaker Addition to the Nucla Plant

The breaker replaced the existing secondary crusher.  Conveyor No. 1A, which feeds this crusher was extended though the north wall of the existing crusher house.  The breaker was located above a tunnel that received the secondary crushed coal and elevates it above grade.  The completed installation and a general arrangement drawing illustrate this modification.
