The contract includes the design and supply of a system for the 428-megawatt net capacity coal-fired steam electric generating unit.
The Craig Station fires Colorado low-sulfur bituminous coal as its primary fuel. SCR systems reduce nitrogen oxide (NOx) emissions, a contributor to the formation of ozone and smog.
The SCR system being furnished by HPSA will utilize Hitachi’s state-of-the-art catalyst, offering high NOx removal efficiencies over a wide operating load range. This leading edge technology will help Tri-State Generation meet or exceed its NOx reduction requirements while keeping sulfur trioxide (SO3) emissions low.
This highly reliable system is being designed for continuous operation throughout the year.
