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.
