Available in PDF, EPUB and Kindle. Book excerpt: The LNCB[trademark] project involves retrofitting the two-nozzle cell burners at Dayton Power Light's, 605 HWe J.M. Stuart Unit [number sign]4 Boiler near Aberdeen, Ohio with LNCB[trademark] (a burner and intregal NOx port). Previous pilot-scale tests have shown such an arrangement to achieve 50% reduction in NOx emission levels. This full-scale project will determine the commercial applicability of this technology. Fabrication and installation of all materials for the burner inversion and impeller change was completed during this quarter. The outage work, which began April 27th and concluded with the unit returning on line May 9th, went very smoothly. The parametric testing phase of the project actually began May 14th after correcting test equipment problems. Preliminary results show that the impeller change and burner inversion were successful. The Low NOx Cell[trademark] burners achieved better than 50% NOx reduction and carbon monoxide (CO) inside the lower furnace is less than 1000 ppm.

Book excerpt: The Republic of Korea's industrial policy has directed that nation's economy through nearly three decades of spectacular growth. But the authors of this paper maintain that this policy is showing signs of being outmoded. The time has come, the authors argue, for the Korean government to stop managing the economy's structural development and to redefine the responsibilities of business and government. Under this proposed compact, the allocation of resources would shift from the government to the private industrial and financial sectors. The transformation of the government bureaucracy from an ad hoc policy role to one of a transparent and predictable regulator is a key to the success of this undertaking. These new directions would present the government with enormous challenges. Greater competitive discipline and regulatory oversight would be required. While dealing with the complexities of the transition, the government would have to maintain macroeconomic stability and the momentum of savings and investment. For comparison, the study examines the industrial economies of France, Germany, Japan, and the United States, which underwent similar shifts.

This book was released on 1992 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objectives of the full-Scale Low-NOx Cell{trademark} Burner (LNCB{trademark}) Retrofit project is to demonstrate the cost-effective reduction of NOx generated by a large, base-loaded (70% capacity factor or greater), coal-fired utility boiler. Specific objectives include: (1) At least 50% NOx reduction over standard two-nozzle cell burners, without degradation of boiler performance or life; (2) acquire and evaluate emission and boiler performance data before and after the retrofit to determine NOx reduction and impact on overall boiler performance; (3) demonstrate that the LNCB{trademark} retrofits are the most cost-effective alternative to emerging, or commercially-available NOx control technology for units equipped with cell burners. The focus of this demonstration is to determine maximum NOx reduction capabilities without adversely impacting plant performance, operation and maintenance.

In particular, the prototype evaluations will resolve many technical issues not possible to address fully in the previous pilot-scale work and the single full-scale burner installation.

This book was released on 1993 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Full Scale Demonstration Low-NO(subscript x) Cell{trademark} Burner (LNCB{trademark}) project involves retrofitting the two-nozzle cell burners at Dayton Power and Light's, 605 MW(e) J.M. Stuart Unit No. 4 boiler near Aberdeen, Ohio with LNCB{trademark} (a burner and integral No(subscript x) port). Previous pilot-scale tests have shown such an arrangement to achieve 50% reduction in NO(subscript x) emission levels. This full-scale project will determine the commercial applicability of this technology. Long-term testing via a Continuous Emission Monitor (CEM) began in August, 1992. CEM testing will continue until Spring of 1993 when Unit No. 4 comes off line for its annual outage which at this time is scheduled for April 4, 1993. A key item remaining to be evaluated as part of the long term testing is furnace tube wall corrosion. H2S probing similar to optimized test probing was repeated during the week of August 17, 1992. During the Spring '93 outage, ultrasonic testing of the furnace wall tubes as well as destructive examination of samples from the corrosion test panel will be accomplished.

Available in PDF, EPUB and Kindle. Book excerpt: As part of this DOE's demonstration program, a corrosion test panel was installed on the west sidewall of Dayton Power & Light Unit no. 4 at the J.M. Stuart Station (JMSS4) during the burner retrofit outage in November 1991. The test panel consisted of four sections of commercial coatings separated by bare SA213-T2 tubing. During the retrofit outage, a UT survey was performed to document the baseline wall thicknesses of the test panel, as well as several furnace wall areas outside the test panel. The purpose of the UT survey was to generate the baseline data so that the corrosion wastage associated with the operation of Low NO(subscript x) Cell Burners (LNCB{trademark} burner) could be quantitatively determined. The corrosion test panel in JMSS4 was examined in April 1993 after the first 15-month operation of the LNCB{trademark} burners. Details of the corrosion analysis and UT data were documented in the Long-Term Testing Report. The second JMSS4 outage following the LNCB{trademark} burner retrofit took place in September 1944. Up to this point, the test panel in JMSS4 had been exposed to the corrosive combustion environment for approximately 31 months under normal boiler operation of JMSS4. This test period excluded the down time for the April 1993 outage. During the September 1994 outage, 70 tube samples of approximately one-foot length were cut from the bottom of the test panel. These samples were evaluated by the Alliance Research Center of B & W using the same metallurgical techniques as those employed for the previous outage. In addition, UT measurements were taken on the same locations of the lower furnace walls in JMSS4 as those during the prior outages. Results of the metallurgical analyses and UT surveys from different exposure times were compared, and the long-term performance of waterwall materials was analyzed. The corrosion data obtained from the long-term field study at JMSS4 after 32 months of LNCB{trademark} burner operation are summarized in this report.

Available in PDF, EPUB and Kindle. Book excerpt: The Low-NO(subscript x) Cell{trademark} Burner (LNCB) concept was developed by Babcock & Wilcox (B & W) to effectively reduce the NO(subscript x) emissions from pulverized-coal-fired boilers equipped with cell burners. These boilers were built mostly in the mid to late 1960s. Small (6-million Btu/hr) and intermediate (100-million Btu/hr) prototype versions of the concept were developed jointly by B & W and the Electric Power Research Institute (EPRI) during the mid-to-late 1980s. The design of B & W LNCBs allows direct replacements of the originally installed cell burners without pressure-part modifications. During this US Department of Energy (DOE) Clean Coal III program, Dayton Power and Light Company (DP & L) served as the host utility using its J.M. Stuart Station Unit {number_sign}4 (JMSS 4) for the first full-scale LNCB demonstration. This unit has a rated output capacity of 605 MW{sub e}. After the LNCB retrofit and burner optimization contract phases in late 1991, JMSS 4 underwent a long- term (nine months) test period from July 1992 to March 1993. The objective of this test was to determine the overall performance of this boiler after the LNCB retrofit. The long-term test involved determinations of the boiler emission performance and evaluations of waterwall corrosion potential, as well as a study of the overall operability of the LNCB system. Specific tasks performed during this long-term test include: (1) laboratory corrosion study; (2) field corrosion panel study; (3) in-furnace gas species probing; and (4) boiler emissions performance study. This report summarizes the long- term test results.
