Experiences with the installation of new gas boiler and turbine/generator at Western Sugar Cooperative, Scottsbluff location.

Western Sugar Cooperative in Scottsbluff, NE recently installed two new Babcock and Wilcox shop assembled package natural gas boilers. The boilers are a model FM120-136 water tube design capable of providing 225,000 pounds per hour each of 600⁰F steam at 400 psig. The reasons for the installation include: unreliable and aged coal boilers, environmental regulatory requirements, and lessening of personnel load. Howden MONO AFA 6 single blade turbine coupled with a 7MW TDPS generator was installed and commissioned the following year. Westinghouse 5MW AC turbine generator had failed two years prior. This paper aims to provide lessons learned for future factory boiler conversions and installations.
