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.
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.
