Two dimensional NMR and NMR relaxation studies of coal structure

Description: This report covers the progress made on the title project for the project period. Four major areas of inquiry are being pursued. Advanced solid state NMR methods are being developed to assay the distribution of the various important functional groups that determine the reactivity of coals. Special attention is being paid to methods that are compatible with the very high magic angle sample spinning rates needed for operation at the high magnetic field strengths available today. Polarization inve… more

Development of advanced NO sub x control concepts for coal-fired utility boilers

Description: CombiNO{sub x} is an integration of three technologies: modified reburning, promoted selective noncatalytic reduction (SNCR) and methanol injection. These technologies are combined to achieve high levels of NO{sub x}, emission reduction from coal fired power plants equipped with SO{sub 2} scrubbers. The first two steps, modified reburning and promoted SNCR are linked. It has been shown that, performance of the SNCR agent is dependent upon local oxidation of CO. Reburning is used to generate the… more

Analysis of K-Area core samples for K-Area formation stabilization work

Description: Foundation stabilization work in K-Area has been recently completed by Bechtel Inc. This effort involved pumping cement and cement-sand grout into unconsolidated sediments under K-Area. Subsequent to stabilization, core samples were collected to document the extent of grout flow in the area. Samples of this core were examined by SRTC personnel in support of the grouting program at the request of Bechtel personnel. This report summarizes the results of the SRTC study.

High temperature alkali corrosion of ceramics in coal gas. Quarterly progress report No. 3, March 1, 1992--May 31, 1992

Description: High temperature alkali corrosion has been known to cause premature failure of ceramic components used in advanced high temperature coal combustion systems such as coal gasification and clean-up, coal fired gas turbines, and high efficiency heat engines. The objective of this research is to systematically evaluate the alkali corrosion resistance of the most commonly used structural ceramics including silicon carbide, silicon nitride, cordierite, mullite, alumina, aluminum titanate, zirconia, an… more

CP Violation in the Decays B sup 0 Yields. Psi. K sub s and B sup 0 Yields. pi. sup +. pi. sup minus : A Probe for New Physics

Description: We point out the strong correlation between the CP-violating asymmetries in the decays B{sup o} {yields} {Psi}K{sub s} and B{sup o} {yields} {pi}{sup +}{pi}{sup {minus}} that is predicted by the Kobayashi-Maskawa model. This results in a very restricted allowed region for the asymmetries, and so their measurement will provide a powerful test of the standard model. To show how new physics may give very different results, we look at the predictions of a simple model where both the standard model … more

Fundamental mode frequency of the storage ring single cell cavity

Description: The fundamental mode frequency of the prototype storage ring cavity has been measured with various port terminations and cavity temperatures. Since the highest tuned frequency of the prototype cavity with a tuner under the high RF power test condition is measured to be lower than the system specified frequency, a slight dimensional change in the cavity design is required for manufacturing future cavities. In addition to this, an extra dimensional correction is required to compensate the volume … more
