LIME FGD SYSTEMS DATA BOOK - SECOND EDITION.

Selecting and installing a flue gas desulfurization (FGD) can be a difficult task for the utility engineer. Often, the technology is unfamiliar and the array of alternatives extensive and varied. Approximately 33,000 MW of FGD systems are presently operating on electric utility boilers and another 39,000 MW are planned or under construction. With the current New Source Performance Standards (NSPS) for sulfur dioxide (SO//2) requiring an FGD system on essentially every new coal-fired utility generating unit, the ability to decide on the most advantageous FGS system based on technical, environmental, and economic considerations is critical to the success of the unit and can result in substantial improvements in the reliability of the system. This manual presents discussions of the chemical processes involved in SO//2 removal using lime, process control methods, mechanical component design, and methods of requesting and evaluating proposals. The discussion of mechanical components includes numerous examples of existing utiliuty FGD installations and problems.
