Advanced Tangentially Fired Combustion Techniques for the Reduction of NitrogenOxides (NOx) Emissions from Coal-Fired Boilers Demonstration Project: A DOE Assessment

摘要

This document serves as a DOE post-project assessment of a project in Round 2 ofthe Department of Energys Clean Coal Technology (CCT) Program: Advanced Tangentially Fired Combustion Techniques for the Reduction of Nitrogen Oxides (NOx) Emissions From Coal-Fired X Boilers Demonstration Project. In September 1990, Southern Company Services entered into an agreement to conduct the study, with Gulf Power Company providing the 180 megawatt electric (MWe) host site and ABB C-E Services Inc. providing the technology to be demonstrated. This project was undertaken to evaluate the nitrogen oxides (NOx) reduction potential of several X variations of the Low NO Concentric Firing System (LNCFS) when applied to tangentially X TM fired (T-fired) boilers. The project consisted of replacing the existing coal and air nozzles with new nozzles and adding overfire air.
