Book excerpt: This first Quarterly Technical Progress Report presents the results of work accomplished during the period April 19 through July 24,1988. The overall objective of the program is the development of a pulsed atmospheric fluidized-bed combustion (PAFBC) technology to burn coal and to provide heat and steam to commercial, institutional, and small industrial applications at a reasonable price in an environmentally acceptable manner. the program scope consisted of two tasks; the first was to establish preliminary feasibility by the use of theoretical and state-of-the-art information. This task was completed during the first quarter of the contract period and a topical report entitled, ''Pulsed Atmospheric Fluidized Bed combustion (PAFBC) - Preliminary Feasibility Study'' was prepared as a ''decision point to proceed'' deliverable in accordance with the terms of the contract. This first quarterly progress report therefore covers the contract activities subsequent to the approval of the feasibility study and the decision to proceed with the Task 2 effort. As the initial quarterly technical progress report, this document includes a subsection on background which will be omitted in subsequent reports. All effort during this period was devoted to the design and analysis of the PAFBC. Design drawings were prepared and fabrication and procurement initiated. Quotations were evaluated and a fabrication contract awarded. A site adjacent to the MTCI building was chosen for the installation of the PAFBC. Some ancillary components were purchased, renovated, and tested. Some delays in delivery of components have resulted in some schedule delay. It is anticipated that the program pace will accelerate as soon as parts are received and installation and assembly are initiated. 10 figs.,1 tab.

Book excerpt: The overall objective of the program is the development of a pulsed atmospheric fluidized-bed combustion (PAFBC) technology to burn coal and to provide heat and steam to commercial, institutional, and small industrial applications at a reasonable price in an environmentally acceptable manner. During this reporting period, a total of eight shakedown and debugging coal combustion tests were performed in the AFBC. A start-up procedure was established, system improvements implemented, and preliminary material and heat balances made based on these tests. The pulse combustor for the AFBC system was fabricated and installed and a series of tests was conducted on the system. 17 figs., 5 tabs.

This book was released on 1991 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major accomplishments during this reporting period include completion of Task 1 and progression into Phase II, Task 2 design activities. A brief laboratory-scale test was conducted during this reporting period to confirm heat transfer coefficients for various sections of the Pulsed Atmospheric Fluidized bed Combustion (PAFBC) system. The heat transfer coefficient was determined to be approximately 50 Btu/hr ft2 °F inside the eductor and tailpipe of the pulse combustor as thin the fluidized bed. well as for the surfaces immersed within the fluidized bed. Communications with potential host sites for the Phase III field demonstration activities continued during this reporting period. These discussions along with discussions with environmental regulatory personnel in the State of Maryland indicate that the throughput of the field demonstration facility should be increased to greater than 36 million Btu/hr. An 8 in. x 8 in. fluidized bed unit would be too small to satisfy this requirement; its projected firing rate is only 33 million Btu/hr. Major effort during this reporting period was devoted to assessing the reasonableness of increasing the size of the field test facility from a technical and cost standpoint.

This book was released on 1993 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: This quarterly report is broken down between design and the status of the fabrication work being performed. The design section is divided between the following sections: Site layout, foundation design, structural design, piping design, pulse combustor components, and electrical & instrumentation design. As reported in the last quarterly report the location area of the PAFBC in the Clemson Energy Facility was inspected with a view to finalize the layout of the PAFBC plant. Some adjustments were made to the layout to accommodate Clemson University's requirements and the available space. The most important changes are that the boiler and economizer were relocated in the structure above ground level in order to reduce the size of the footprint of the plant. Figure 1 is the plan view of the current layout. Figures 2 through 6 present different elevation views of the layout. The design of foundations for the entire plant is currently being executed by Industra Engineers Inc. of Greenville, SC. The different weights of various equipment located close to each other precludes the provision of independent foundations for each piece of equipment. One monolithic foundation platform for the whole area proves to be more economical for the current layout. In this quarter the design of the plant structures was completed. The drawings were sent out for expert review and approval. The drawings at this stage present complete structural and platform layout requirements. Changes will be made to various structural members based on the structural review and then detailed drawings of joint design and fabrication cutting plans will be prepared and issued for fabrication.

This book was released on 1992 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of the Pulsed Atmospheric Fluidized Bed Combustor (PAFBC) as described in the Quarterly Report for the period April--June, 1992 was reviewed and minor modifications were included. The most important change made was in the coal/limestone preparation and feed system. Instead of procuring pre-sized coal for testing of the PAFBC, it was decided that the installation of a milling system would permit greater flexibility in the testing with respect to size distributions and combustion characteristics in the pulse combustor and the fluid bed. Particle size separation for pulse combustor and fluid bed will be performed by an air classifier. The modified process flow diagram for the coal/limestone handling system is presented in Figure 1. The modified process flow diagrams of the fluidized bed/steam cycle and ash handling systems are presented in Figures 2 and 3, respectively.

This book was released on 1993 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this quarter the design of the plant structures was completed 70%. The design philosophy of the structure economizes on the use of steel by providing supports for the hot cyclone and hot gas duct connecting the cyclone to the boiler while fulfilling the needs for platforms and walkways at the various levels necessary for operational access. Figures 1 through 6 indicate the layout of the plant structure. At the same time the structure for the Coarse Coal Silo V-2 and Limestone Silo V-4 were incorporated and completed. Following completion of the piping pressure drop calculations, pipe sizing and layout drawings, detailed drawings of the piping in different views are being prepared. The pulse combustor is used to burn fine coal particles and provide an ignition source and supplementary heat to the fluid bed. The following is a description of the components: air plenum, fine coal injectors, aerovalves, water jacket, and tailpipe inserts.
