Menzies, W., C. Muela, AND G. Behrens. STACK GAS REHEAT EVALUATION. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/7-80/051 (NTIS PB80196850), 1980.
Description:
The report gives results of technical and economic evaluations of stack gas reheat (SGR) following wet flue gas desulfurization (FGD) for coal-fired power plants. The evaluations were based on information from literature and a survey of FGD users, vendors, and architect/engineer (A/E) firms. The report summarizes SGR processes and their features and their commercial operating experience. It addresses benefits and energy requirements associated with SGR, and describes a developed method for estimating reheat costs. SGR can protect equipment downstream of a wet scrubber from corrosion, reduce the potential for acid rainout near the plant stack, preclude visible stack plumes, and reduce ground-level pollutant concentrations by increasing plume buoyancy.
