This book was released on 1992 with total page 13 pages. 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 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.

This book was released on 1992 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objectives of the full-Scale Low-NO(subscript x) Cell{trademark} Burner (LNCB{trademark}) Retrofit project is to demonstrate the cost-effective reduction of NO(subscript x) generated by a large, base-loaded (70% capacity factor or greater), coal-fired utility boiler. Specific objectives include: (1) At least 50% NO(subscript x) 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 NO(subscript x) 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 NO(subscript x) control technology for units equipped with cell burners. The focus of this demonstration is to determine maximum NO(subscript x) 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.

Available in PDF, EPUB and Kindle. Book excerpt: The basic goal of the Limestone Injection Multistage Burner (LIMB) demonstration is to extend LIMB technology development to a full- scale application on a representative wall-fired utility boiler. The successful retrofit of LIMB to an existing boiler is expected to demonstrate that (a) reductions of 50 percent or greater in SO(subscript x) and NO(subscript x) emissions can be achieved at a fraction of the cost of add-on FGD systems, (b) boiler reliability, operability, and steam production can be maintained at levels existing prior to LIMB retrofit, and (c) technical difficulties attributable to LIMB operation, such as additional slagging and fouling, changes in ash disposal requirements, and an increased particulate load, can be resolved in a cost-effective manner. The primary fuel to be used will be an Ohio bituminous coal having a nominal sulfur content of 3 percent or greater.

Download or read book The Mobility of Displaced Syrians written by World Bank and published by World Bank Publications. This book was released on 2020-01-27 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The war in Syria, now in its eighth year, continues to take its toll on the Syrian people. More than half of the population of Syria remains displaced; 5.6 million persons are registered as refugees outside of the country and another 6.2 million are displaced within Syria's borders. The internally displaced persons include 2 million school-age children; of these, less than half attend school. Another 739,000 Syrian children are out of school in the five neighborhood countries that host Syria's refugees. The loss of human capital is staggering, and it will create permanent hardships for generations of Syrians going forward. Despite the tragic prospects for renewed fighting in certain parts of the country, an overall reduction in armed conflict is possible going forward. However, international experience shows that the absence of fighting is rarely a singular trigger for the return of displaced people. Numerous other factors—including improved security and socioeconomic conditions in origin states, access to property and assets, the availability of key services, and restitution in home areas—play important roles in shaping the scale and composition of the returns. Overall, refugees have their own calculus of return that considers all of these factors and assesses available options. The Mobility of Displaced Syrians: An Economic and Social Analysis sheds light on the 'mobility calculus' of Syrian refugees. While dismissing any policies that imply wrongful practices involving forced repatriation, the study analyzes factors that may be considered by refugees in their own decisions to relocate. It provides a conceptual framework, supported by data and analysis, to facilitate an impartial conversation about refugees and their mobility choices. It also explores the diversified policy toolkit that the international community has available—and the most effective ways in which the toolkit can be adapted—to maximize the well-being of refugees, host countries, and the people in Syria.
