Book excerpt: The goal of the NO(subscript x) Subsystem is to achieve continuous operation of the Low-Emissions Boiler System (LEBS) at NO(subscript x) emissions at or below 0.20 lb/MBtu through combustion techniques only, with a further target of 0.1 lb NO(subscript x)MBtu using supplementary advanced flue gas cleanup technologies if necessary. These goals places practical constraints that must be considered on the NO(subscript x) Subsystem design. Not only must the boiler be designed to achieve time-temperature mixing histories that minimize NO(subscript x), but it must also be designed to operate that way throughout its working lifetime. Therefore, NO(subscript x) minimization strategies must be integrated into the control systems for every boiler component from the pulverizers to the stack. Furthermore, these goals must be met without increases in carbon loss and CO emissions from the levels achieved with current low-NO(subscript x) combustion systems. Therefore, the NO(subscript x) Subsystem requires not only sound mechanical designs of burners, furnace surface, and staging air/fuel injectors, but also sensors and software to allow control of their operation. Through engineering analysis, experimental testing, and numerical modeling in Phase II, an advanced low-NO(subscript x) control system is being developed. The progress of these activities is presented in this report.

This book was released on 1997 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the work performed between October 1 and December 31, 1996 by the ABB team on U.S. Department of Energy project ''Engineering Development of Advanced Coal-Fired Low-Emission Boiler Systems'' (LEBS), which is part of the DOE's Combustion 2000 Program. The overall objective of the LEBS Project is to dramatically improve environmental performance of future coal-fired power plants without adversely impacting efficiency or the cost of electricity. Near-term technologies, i.e., advanced technologies that are partially developed, will be used to reduce NO(subscript x) and SO2 emission to one-sixth current NSPS limits and particulates to one- third current NSPS limits.

Book excerpt: Preliminary sketches of the furnace setting with dimensions and other appropriate data was distributed to appropriate boiler design groups. The purpose of this work was to define and/or establish unique mechanical and support requirements and furnace water circulation requirements. A preliminary convection pass arrangement and heating surface requirements were established. Initial computer runs indicate, as expected, that establishing even a preliminary arrangement to meet steam duty requirements was going to be a challenge. This due to slightly lower furnace exit gas temperatures (result of NO(subscript x) control conditions) and higher final steam temperatures (results increasing plant efficiency) than typical of conventional design. Work on the furnace and convection pass design for the base preliminary unit was completed only to the extent necessary to identify design deficiencies, prepare an arrangement drawing and determine budgetary cost. Engineering work has been completed to the extent planned in this subtask for the base preliminary unit, Advanced Overfire Air, including preliminary designs for the furnace, convection pass, pulverizers, airheaters, flues and ducts, preliminary general arrangement drawings, and budgetary cost estimates. Work is nearly complete on design of the LEBS unit control system based on control methods and philosophy established in the NO(subscript x) Control Subsystems. All appropriate information has been forwarded to Raytheon for use in completing BOP subsystem designs, site plot plans and preliminary generating plant cost analysis and comparison to a conventional plant.

Book excerpt: Of activities and key accomplishments are presented for the following tasks: NO(subscript x) subsystem; SO2 particulate/air toxics/solid by-product subsystem; boiler subsystem; balance of plant subsystem; and control and sensors subsystem. Combustion cases completed for the DRB-XCL{reg_sign} burner and the initial DRB-4Z{trademark} configuration were compared with measured furnace exit data and observed flame characteristics from the initial round of Subsystem Testing to baseline the models prior to parametric runs. A series of combustion models have been completed for the DRB-4Z{trademark} to evaluate the distributed introduction of secondary combustion air into the flame and key hardware components planned for the May Subsystem Testing campaign. On the basis of the results compiled during the concept selection process completed in Phase I, the Limestone Injection Dry Scrubbers (LIDS) process was selected for further development and evaluation. Through engineering analysis, experimental testing, and numerical modeling, a LIDS process is being developed that is capable of ultra-high SO2 removal and superior particulate control while addressing the potential issues of air toxic emissions and solid byproduct utilization. The progress of the LIDS activities is discussed in this report.

This book was released on 1994 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major task during this quarter was testing and evaluation of the 25 MBtu/hr Toroidal Vortex Combustor (TVC) at Textron Defense Systems'' (TDS) Haverhill laboratories. The tests were completed and the results are being evaluated along with other scale up and integration issues. The preliminary conclusion is that the NOx performance and current design uncertainties do not justify the development risk within the Low Emission Boiler System (LEBS) timetable. Further program effort will focus on advanced U-firing arrangements. The second major effort during the period was the engineering development of the moving bed copper oxide system for SOx/NOx control. Through application of a DOE-developed model and the team's engineering analysis, significant progress was made on developing an improved process design. Work began on a small scale test of the moving bed concept under realistic temperature and dust loading conditions. Work continued through the quarter on finalizing the Preliminary Engineering Design, Design Deficiency Analysis, and Research, Development, and Test Plan. The Design and Development Report containing these three deliverables was released in March. Sargent & Lundy printed and distributed the report to team members, as well as to the advisory panelists. The advisory panel numbers approximately fifteen organizations as of the end of the period.
