Integrated Dry NOx/SO2 Emissions Control System, A DOE Assessment

PDF Version Also Available for Download.

Description

The goal of the U.S. Department of Energy's (DOE) Clean Coal Technology (CCT) Program is to furnish the energy marketplace with a number of advanced, more efficient, and environmentally responsible coal utilization technologies through demonstration projects. These projects seek to establish the commercial feasibility of the most promising advanced coal technologies that have developed beyond the proof-of-concept stage. This document serves as a DOE post-project assessment (PPA) of a project selected in CCT Round III, the Integrated Dry NO{sub x}/SO{sub 2} Emissions Control System (IDECS), as described in a Report to Congress (U.S. Department of Energy 1991).

Description

The goal of the U.S. Department of Energy's (DOE) Clean Coal Technology (CCT) Program is to furnish the energy marketplace with a number of advanced, more efficient, and environmentally responsible coal utilization technologies through demonstration projects. These projects seek to establish the commercial feasibility of the most promising advanced coal technologies that have developed beyond the proof-of-concept stage. This document serves as a DOE post-project assessment (PPA) of a project selected in CCT Round III, the Integrated Dry NO{sub x}/SO{sub 2} Emissions Control System (IDECS), as described in a Report to Congress (U.S. Department of Energy 1991). The desire to reduce emissions of nitrogen oxides (NO, nitric oxide, and NO{sub 2}, nitrogen dioxide, collectively referred to as NO{sub x}) and sulfur dioxide (SO{sub 2}) by up to 70 percent at a minimum capital expenditure, while limiting waste production to dry solids that can be handled by conventional ash-removal equipment, prompted Public Service Company of Colorado (PSCC) to submit the proposal for the IDECS project. In March 1991, PSCC entered into a cooperative agreement with DOE to conduct the study. The project was sited at PSCC's Arapahoe Steam Electric Generating Station in Denver, Colorado. The purpose of this CCT project was to demonstrate the reduction of NO{sub x} and SO{sub 2} emissions by installing a combination of existing and emerging technologies, which were expected to work synergistically to reduce emissions. The technologies were low-NO{sub x} burners (LNBS), overfire air (OFA), and selective noncatalytic reduction (SNCR) for NO{sub x} reduction; and dry sorbent injection (DSI), both with and without flue-gas humidification (FGH), for SO{sub 2} reduction. DOE provided 50 percent of the total project funding of $26.2 million.
