چکیده
The facility is located four miles east of Hayden in Routt County, and consists of two BART-eligible boilers. Unit #1 is rated at 190 MW and is dry-bottom, wall-fired. Unit #2 is rated at 275 MW and is tangentially-fired. The Hayden boilers burn Colorado coal that primarily comes from two different mines in northwestern Colorado, the Twenty Mile Mine and the ColoWyo Mine. Coal characteristics are very similar from both of these mines. ColoWyo coal is ranked as sub-bituminous while the Twenty Mile coal is ranked as bituminous. According to CDPHE, PSCo performed an analysis to demonstrate that the more appropriate rating for ColoWyo coal is bituminous.
