Abstract:

An evaluation of the Malmstrom Air Force Base MAFB coal-fired Central Heat Plant CHP was begun in January 1995. The system was evaluated and tested, on-site improvements were made, and recommendations were made to continue improved system performance. Local conditions favor continued use of coal technology, and it was found that the control equipment, as installed, will perform at the level required to meet environmental regulatory standards. However, since the control equipment at MAFB is 10 years old, the installation may further improve operations by renewing the present boiler controls. Operation of the spray dryer equipment may also be improved by correcting problems involving low exit temperatures by raising the temperature at the inlet to the spray dryer. Tests proved conclusively that the existing SO2 removal system can be operated to achieve removal rates higher than 85 percent. However, investigation revealed a significant equipment problem the baghouse flue gas outlet emission monitor gives unacceptable, operationally unreliable readings. If MAFE continues to use this inadequate equipment, such incorrect readings will likely cause further regulatory problems.
