The fabric filter baghouse of the Nucla Colorado Station of the Colorado Ute Electric Association was evaluated with a field performance test and engineering analysis. The overall collection efficiency determined with impactors was 99.92% at 12 Mw with outlet mass concentrations of less than 0.0011 gr/ft/sup 3/. The outlet opacity was measured to be less than 1%. The unit capital cost (including all retrofit construction costs related to the collector) was $87/kw. The operating costs are 1.53 mills/kwh for 1976 based on a 55% capacity factor. The installation of thimble flow straighteners reduced premature bag failures due to bag erosion. The bag replacement was 18% of the total during the first two-year period (most prior to installation of the thimbles). The unit availability has been 100% since installation and the compartment availability has been 99.8%.
