This book was released on 1995 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The University of Utah, Massachusetts Institute of Technology (MIT), Reaction Engineering International (REI) and ABB/Combustion Engineering have joined together in this research proposal to develop fundamental understanding regarding the impact of fuel and combustion changes on ignition stability and flame characteristics because these critically affect: NO(subscript x) emissions, carbon burnout, and emissions of air toxics; existing laboratory and bench scale facilities are being used to generate critical missing data which will be used to improve the NO(subscript x) and carbon burnout submodels in comprehensive combustion simulation tools currently being used by industrial boiler manufacturers. To ensure effective and timely transfer of This technology, a major manufacturer (ABB) and a combustion model supplier (REI) have been included as part of the team from the early conception of the proposal. ABB/Combustion Engineering is providing needed fundamental data on the extent of volatile evolution from commercial coals as well as background information on current design needs in industrial practice. MIT is responsible for the development of an improved char nitrogen oxidation model which will ultimately be incorporated into an enhanced NO{sup x} submodel. Reaction Engineering International is providing the lead engineering staff for the experimental studies and an overall industrial focus for the work based on their use of the combustion simulation tools for a wide variety of industries. The University of Utah is conducting bench scale experimentation to (1) investigate alternative methods for enhancing flame stability to reduce NO(subscript x) emissions and (2) characterize air toxic emissions under ultralow NO(subscript x) conditions. Accomplishments for this quarter are presented to the solid sampling system and char nitrogen modeling.

This book was released on 1996 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the mechanisms of char-N oxidation and reduction is necessary for the accurate modeling of NO, formation from coal combustion. This statement is especially true for combustors where low- NO(subscript x) combustion modification techniques have been applied because in such cases the fraction of total fuel- NO(subscript x) coming from the char is very high. This study has focused on obtaining experimental data that can be used to evaluate char-N oxidation and reduction mechanisms. The ultimate goal is to use this knowledge to improve the NO(subscript x) submodel in an existing computational fluid dynamics (CFD) code. Several key experimental results were outlined in the report for the quarter ending 6/96. In order to clarify certain conclusions, more data were collected and analyzed during the quarter ending 9/96. Results from these new data as well as important results not included in the 6/96 report are addressed here.

This book was released on 1996 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Direct coal combustion must be a primary energy source for the electric utility industry and for heavy manufacturing during the next several decades because of the availability and economic advantage of coal relative to other fuels and because of the time required to produce major market penetration in the energy field. However, the major obstacle to coal utilization is a set of ever-tightening environmental regulations at both the federal and local levels. It is, therefore, critical that fundamental research be conducted to support the development of low-emission, high efficiency pulverized coal power systems.

ABB/Combustion Engineering is providing needed fundamental data on the extent of volatile evolution from commercial coals as well as background information on current design needs in industrial practice. Since they will ultimately be a recipient of the enhanced design methodology, they are also providing ongoing review of the practical applicability of the tools being developed. MIT is responsible for the development of an improved char nitrogen oxidation model which will ultimately be incorporated into an enhanced NO(subscript x) submodel. Reaction Engineering International is providing the lead engineering staff for the experimental studies and an overall industrial focus for the work based on their use of the combustion simulation tools for a wide variety of industries. The University of Utah is conducting bench scale experimentation to (1) investigate alternative methods for enhancing flame stability to reduce NO(subscript x) emissions and (2) characterize air toxic emissions under ultra-low NO(subscript x) conditions because it is possible that such conditions will alter the fate of volatile and semivolatile metal species and the emission of heavy hydrocarbons. Finally the University of Utah is responsible for the development of the improved NO(subscript x) and carbon burnout submodels.

Book excerpt: The development of advanced flue-gas-cleanup (FGC) technologies fro the control of sulfur dioxide (SO2) and nitrogen oxides (NO(subscript x)) emissions continues to be a very active area of research and development, both in this country and abroad. This activity is driven both by legislation (such as the recent revisions to the Clean Air Act) and by the desire to develop technologies that surpass current options in terms of performance, costs, operability, and waste/by-product properties. New issues, such as concern over global climate changes and the health effects of toxic air emissions (''air toxics''), are also helping to shape and prioritize the development programs. This paper provides a status report on a number of integrated FGC systems that have reached a significant stage of development, focusing on post-combustion processes that have been rested or are ready for testing at the pilot scale or larger. While some information that was presented at the 1991 CIBO NO(subscript x) IV Control Conference is repeated for the sake of completeness, we have updated each section to reflect the most recent reported developments. Although a wide variety of technologies is discussed, it should be noted that there are a number of other integrated approaches, such as slagging combustors, fluidized-bed combustion, gasification/combined-cycle systems, and various processes combining low-NO(subscript x) burners with SO2-sorbent injection in the furnace. These other approaches also offer features that should not be overlooked when evaluating alternatives for a specific application.
