Scale-up circulating fluidized bed coal combustors

Description: Circulating fluidization is a promising technology for designing efficient coal combustors with high solid feed rates. Unfortunately, limited understanding of circulating fluidized beds (CFB) has rendered design extrapolations from pilot reactors to full-scale plants both empirical and expensive. In CFBs, hydrodynamics and heat transfer are difficult to predict, and the behavior of the flow under scale-up is unclear. Thus the objectives of this research were to quantify the effect of scale-up o… more

Moessbauer spectroscopy at pressures up to 40 GPa

Description: Mossbauer spectroscopy (MS) is a viable non-contact'' technique applicable to high-pressure, diamond anvil cells (DAC) with samples containing a wide variety of the elements suitable for MS. The convenience and simplicity of diamond anvil cells as a means to obtain static high pressures even into the megabar regime has resulted in a renewed interest in pressure as a complement to the usual physical measurements. However, the required small sample size and the difficulty of communicating with th… more

Development of a coal quality expert. Technical progress report No. 6, [July 1--September 30, 1991]

Description: The project will provide the utility industry with a PC expert system to confidently and inexpensively evaluate the potential for coal cleaning, blending, and switching options to reduce emissions while producing lowest cost electricity. Specifically, this project will: (1) Enhance the existing Coal Quality Information System (CQIS) database and Coal Quality Impact Model (CQIM) to allow confident assessment of the effects of cleaning on specific boiler cost and performance; (2) Develop and vali… more

Cupola modeling research: Phase 2 (Year one), Final report

Description: Objective was to develop a mathematical model of the cupola furnace (cast iron production) in on-line and off-line process control and optimization. In Phase I, the general structure of the heat transfer, fluid flow, and chemical models were laid out, providing reasonable descriptions of cupola behavior with a one-dimensional representation. Work was also initiated on a two-dimensional model. Phase II was focused on perfecting the one-dimensional model. The contributions include these from MIT,… more

Women in the Armed Forces

Description: Women have become an integral part of the armed forces, but they are excluded from most combat jobs. Several issues remain. One is whether to reduce, maintain, or expand the number of women in the services as the total forces are being reduced. A second question is to what extent women should continue to be excluded from some combat positions by policy. Would national security be jeopardized or enhanced by increasing reliance on women in the armed forces? Should women have equal opportunities a… more
