Available in PDF, EPUB and Kindle. Book excerpt: Construction and installation of the quarter-scale cold model of the Tidd pressurized bubbling bed combustor is complete. The cyclone and filter box have been installed, and the bed is fully instrumented. A data acquisition system has been set up to obtain time-varying pressure measurements from the cold model. Additional software to reduce orifice plate pressure drop measurements into flows, was completed. The capability to calculate the power spectral density (PSD) and probability density function (PDF) for the pressure fluctuation data has also been established. The last major work item remaining before data can be obtained from the model is to segregate the cold bed particles to obtain the required mean particle diameter and size distribution. As mentioned in the last quarterly report, a linear low-density polyethylene produced by Union Carbide was chosen as the cold bed material. Union Carbide distributes the granular polyethylene in 1200 lb{sub m} boxes. The large volume of particles makes the use of standard laboratory sieving methods impractical. We are currently attempting to segregate the particles by fluidizing them in the cold model. Different size particles will be carried out of the bed at different superficial velocities depending on their terminal velocities. The elutriated particles can then be collected using the cyclone separator.

This book was released on 1993 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides a summary of the technical progress made during the third quarter of the first budget period on Cooperative Agreement No. DE-FC21-92MC29264, ''Scaling of Pressurized Beds.'' Significant progress has been made on the construction of the MIT cold scale model of the Tidd pressurized bubbling fluidized bed combustor. As discussed in the Continuation Application for Cooperative Agreement No. DE-FC21-92MC29264, the final design is a 4:1 scale model of the Tidd combustor based on the simplified set of scaling laws. The model is roughly 8 feet high and has a cross section of 1.5 ft. x 2.8 ft. The cold model design captures 11ft-2in. of the 14ft width and 6ft of the 23ft depth of the Tidd bed along with the full height. The experimental apparatus design consists of four major components: Instrumentation and data acquisition; Fluidized bed; Particle separation, resupply, filtration equipment; and Piping and support structure. Currently, construction of the cold bed is nearly complete. The only work remaining on the bed itself is the construction and installation of the scaled tube bundle, and completion of the joint between the inlet plenum, the distributor plate, and the particle bed.

Download or read book Pressure Fluctuations as a Diagnostic Tool for Fluidized Beds Quarterly Technical Progress Report January 1 1995 March 31 1995 written by and published by . This book was released on 1995 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of preliminary experiments were conducted at the Iowa State University power plant circulating fluidized bed boiler (CFB). Pressure fluctuation measurements were recorded from a pressure transducer located immediately above the primary air distributor at the base of the CFB boiler under normal operating conditions. The purpose of these initial experiments was to examine the general pressure fluctuation structure of the fluidized bed boiler in order to assess what further signal processing techniques may be necessary for valid pressure fluctuation analysis and analytical characterization. These initial results show that the CFB boiler pressure fluctuations obtained are highly periodic. Due to the dominance of this periodic component (and its subsequent harmonics), the Bode plots of these pressure fluctuation signals are difficult to interpret. While an overall system roll-off is apparent, neither the overall system order nor the system time constants can be adequately estimated from this initial data. Further data recorded from other locations in the CFB boiler should provide a more complete explanation of the nature of boiler pressure fluctuations. This initial experimentation suggests that a better description of pressure fluctuations could be attained using signal filtering techniques. Numerous experiments were also completed using the 2.0 inch diameter cold-model CFB, completing the first stage of a comprehensive set of similitude experiments. This bed was pressurized, and fluidized with 0.15 and 0.2 mm steel shot. A variety of operating conditions were selected such that similitude parameters could be matched in a 4.0 inch diameter CFB model exactly twice the scale of this small CFB. Currently, the final similitude tests in the small CFB with 0.1 mm steel shot are being performed.

Download or read book Thermal Energy written by Yatish T. Shah and published by CRC Press. This book was released on 2018-01-12 with total page 1112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book details sources of thermal energy, methods of capture, and applications. It describes the basics of thermal energy, including measuring thermal energy, laws of thermodynamics that govern its use and transformation, modes of thermal energy, conventional processes, devices and materials, and the methods by which it is transferred. It covers 8 sources of thermal energy: combustion, fusion (solar) fission (nuclear), geothermal, microwave, plasma, waste heat, and thermal energy storage. In each case, the methods of production and capture and its uses are described in detail. It also discusses novel processes and devices used to improve transfer and transformation processes.
