Integrated Environmental Control

This paper provides an overview of integrated environmental control research and development efforts at the Electric Power Research Institute (EPRI). EPRI studies show that as much as a 50 percent reduction in total environmental control system costs for coal-fired power plants may be achievable by utilities using systematically integrated environmental control design methods. The bulk of these savings can be achieved through consolidation of several functions into one device. The remainder can come from improved plant heat rates, resulting in less fuel consumption and, thus, less flue gas to process and less emissions to control, and from eliminating unnecessary redundant control systems.
