It was written as an aid to utility engineers involved in the design, specification, project management, and operation of lime-based, flue gas desulfurization (FGD) systems.
POWER UTILITY ENGINEERS MANUAL
This manual represents a joint effort of EPRI nd the US Environmental Protection Agency (EPA).
This same information will also prove useful for the engineers responsible for successfully operating the FGD system once it is placed in service. The manual also provides technical details about FGD process design and performance variables and their interactions so that utility engineers can evaluate competing FGD system proposals. The manual highlights more » the various technical and economic decisions that must be made by utility engineers to ensure that they specify and procure an FGD system that is well suited to their specific application. = J in System Modification, Proposal Evaluation, and Design and Part 5-FGD System Case Study. The objectives are to demonstrate how the information contained in Parts 1 and 2 can be used to improve the technical content of an FGD system purchase specification to demonstrate how the techniques presented in Part 3 can be used to evaluate proposals received in response to the purchase specification and to illustrate how the FGDPRISM computer program can be used to establish design parameters for the specification and evaluate vendor designs. Part 5 is a case study in using this manual in the preparation of a purchase specification and in the more » evaluation of proposals received from vendors. The primary objective of Part 4 of this manual is to provide the utility engineer who has a special interest in the capabilities of FGDPRISM with more detailed discussions of its uses, requirements, and limitations. The objectives are to provide procedures for evaluating the technical aspects of proposals, and to provide procedures for determining the total costs of proposals considering both initial capital costs and annual operating and maintenance costs. Part 3 provides an overview of the recommended procedures for evaluating proposals received from FGD system vendors. The objectives of Part 2 are the following: to provide the electric utility engineer with information on equipment that may be unfamiliar to him, including ball mills, vacuum filters, and mist eliminators and to identify the unique technique considerations imposed by an FGD system on more familiar electric utility equipment such as fans, gas dampers, piping, valves, and pumps. Part 2 of this manual provides the electric utility engineer with detailed technical information on some of the major mechanical equipment used in the FGD system.
