Reliability and availability of a flue gas desulfurization (FGD) system is dependent to some extent on adequate system maintenance. System maintenance must be supported by a well planned spare parts program. The objective of this project was to determine the current practices followed by electric utilities in planning spare parts programs. Utilities with operational FGD systems were surveyed to determine the types of practices and typical inventory levels for spare parts for various items of FGD system equipment. FGD system suppliers and consulting engineering firms were also surveyed to obtain their recommendations regarding system sparing philosophy. The survey results were examined to determine significant trends and identify areas where further work could be beneficial. In general, spare parts problems typically have not been a cause for loss of availability except in some specific cases where a late start in planning the spare parts program contributed to problems during early stages of FGD system operation. Computerized methods for inventory surveillance and reordering are replacing manual methods. Stock levels for spare parts typically have been adjusted to reflect the individual utilities' operating experience. Documentation of spare parts usage rates over an extended time period would provide a data base for utilities planning spare parts programs for their first FGD system installation.
