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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The overall objective of the Project is the expedited commercialization of advanced coal-fired low-emission boiler systems. The Project is under budget and generally on schedule. The current status is shown in the Milestone Schedule Status Report included as Appendix A. Under Task 7--Component development and optimization, the CeraMem filter testing was completed. Due to an unacceptably high flue gas draft loss, which will not be resolved in the POCTF timeframe, a decision was made to change the design of the flue gas cleaning system from Hot SNO(subscript x){sup {trademark}} to an advanced dry scrubber called New Integrated Desulfurization (NID). However, it is recognized that the CeraMem filter still has the potential to be viable in pulverized coal systems. In Task 8-- Preliminary POCTF design, integrating and optimizing the performance and design of the boiler, turbine/generator and heat exchangers of the Kalina cycle as well as the balance of plant design were completed. Licensing activities continued. A NID system was substituted for the SNO(subscript x) Hot Process.

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 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Project is under budget and generally on schedule. The current status is shown in the Milestone Schedule Status Report included as Appendix A. Task 7--Component Development and Optimization and Task 11--Subsystem Test Operation and evaluation are shown to be slightly behind schedule. Also, addition of Kalina technology may delay completion of Task 8. However, Phase 2 will be completed on schedule. The Project and plans for the POCTF were presented to the Richmond Power and Light Board of Directors. Technology transfer activities included delivering papers at two conferences, submitting paper abstracts for two other conferences and organizing a Technical Session for a conference. Under Task 7 the 200 acfm CeraMem filter test rig was installed at Richmond Power and Light and testing commenced. Low-NO[sub x] firing system work was essentially completed. In Task 8 integrating and optimizing the performance and design of the boiler, turbine/generator and heat exchangers of the Kalina cycle is proceeding but it has required much more time than anticipated. Preliminary designs of this equipment are nearly complete. Plant design and licensing activities will restart in April. The test designs and plan created in Task 9 were previously submitted and approved, although the plan for the 5,000 acfm CeraMem filter test will be updated following completion of the 200 acfm test. Task 10 work is nearly complete. The test rig for the 5,000 acfm CeraMem test has been shipped to the fabricator's shop, inspected, cleaned and is being modified based on input from the 200 acfm testing. Task 11 work on the CeraMem filter was delayed and is expected to be started during the next reporting period. The second series of combustion testing of the low-NO[sub x] firing system was completed and the data is being analyzed. Early review indicates that 0.1 lb of NO[sub x]/million Btu may be achievable with reasonable stoichiometry and carbon loss.

This coal meets program selection requirements of extensive reserves and production, sulfur content, and representativeness. Two alternate test coals have been selected to examine fuel effects, and to broaden the range of application of the technology being developed. The alternate coals are a medium sulfur, Pittsburgh No. 8 bituminous, and a Wyoming subbituminous coal. The efficiency goals for the LEBS are challenging, particularly with the demands environmental controls are likely to place on auxiliary power. Table 1 shows estimates of overall plant efficiencies for three steam cycles: (1) a 2400 psi subcritical single reheat cycle typical of current plants; (2) a 3500 psi supercritical single reheat cycle; and (3) an advanced 4500 psi double reheat cycle. The plant heat rates are based on maximum boiler efficiency and minimum auxiliary power requirements consistent with conventional plant design for the design and alternate coals. The aggressive efficiency goals clearly require advanced steam conditions, as well as careful management of any added auxiliary power requirements for environmental controls. The EPRI SOAPP (State-of-the-Art Power Plant) project has selected the 4500 psi cycle as maximizing plant efficiency while minimizing generating costs for a commercial plant to be constructed by the year 2000. This program will incorporate the SOAPP base case cycle. The LESS design will incorporate a high-efficiency, once-through boiler design known as the Benson. Significant improvements in availability and operating flexibility have made this boiler design the system of choice for European power generation over the last fifteen years.
