Limestone FGD Systems Data Book. Final Report (25 Units: Location, Capacity, Installation Data, Coal (Calorific Value, Ash, Sulfur Content), Particulate Control System and Design Efficiency)

摘要

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 disconcerting. Approximately 33,000 MW of FGD systems are now operating and another 39,000 MW are planned or under construction. With the current EPA regulations requiring an FGD system on essentially every new coal-fired utility generating unit, the ability to decide on the most advantageous FGD system on technical, environmental, and economic bases 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 sub 2 removal using limestone, process control methods, mechanical component design, and methods of requesting and evaluating proposals. The discussion of mechanical components includes numerous examples of existing utility installations and problems. (ERA citation 08:031604)
