KCPL – La Cygne Station
- Owner: Kansas City Power and Light
- Project: Specialized Belt Feeders
- Location: La Cygne Station, La Cygne, Missouri
- Scope: Engineering, Procurement, Construction, Startup and Commissioning
Roberts & Schaefer Company was awarded a turnkey contract from Kansas City Power and Light for engineering, procurement, construction, start–up and commissioning of the specialized belt feeders for a blending system at Kansas City Power and Light’s La Cygne Station in La Cygne, Missouri. The system was successfully completed and in operation in 1994.
A blending system including specialized belt was added/retrofitted into the coal yard to expand the capacity and improve the physical constraints of the existing system, the nine specialized belt feeders were developed as described below.
The facility now has a single–speed truck unloading belt feeder, 54–inch, 102 FPM, rated at 1,200 TPH of 2–inch X 0 coal. Twin 72–inch wide belt feeders, rated at 1,200 TPH of 2 inch X 0 coal, include variable speed drives that allow belt speeds of 10 to 102 FPM and provide a downturn to 120 TPH minimum. Four 54–inch wide belt feeders, each rated at 1,200 TPH of 2 inch X 0 coal, also include variable speed drives that allow belt speeds of 10 to 102 FPM and provide a downturn to 120 TPH minimum.
Finally, the variable speed drives on twin 120–inch wide belt feeders, rated at 600 TPH of 2 inch X 0 coal, allow belt speeds of 5 to 50 FPM and provide a downturn to 60 TPH. These two feeders are believed to be the largest ever manufactured in the United States.
