The United States currently depends on coal for over half of its electric power generation. Current legislative and regulatory initiatives related to acid rain and other environmental concerns have focused on retrofit controls on existing plants and increasingly stringent requirements for new plants. This paper focuses on some of the technological approaches United States utilities are using and could be using in the future to generate electric power cleanly and reliably. Those technologies discussed include precombustion controls (physical coal cleaning and coal switching/blending), combustion controls (low NO/sub x/ combustion, furnace sorbent injection, and fluidized bed combustion), and postcombustion controls (flue gas NO/sub x/ control, wet and dry flue gas desulfurization, and post-furnace dry sorbent injection). The commercial status, economics, and critical issues for retrofit and new commercial application of these technologies to utility systems are discussed.
