Combustion of ultrafine coal/water mixtures and their application in gas turbines: Final report

Description: The feasibility of using coal-water fuels (CWF) in gas turbine combustors has been demonstrated in recent pilot plant experiments. The demands of burning coal-water fuels with high flame stability, complete combustion, low NO/sub x/ emission and a resulting fly ash particle size that will not erode turbine blades represent a significant challenge to combustion scientists and engineers. The satisfactory solution of these problems requires that the variation of the structure of CWF flames, i.e., … more

Development of Megasonic cleaning for silicon wafers

Description: The Megasonic cleaning system was integrated and debugged. The system consists of the Megasonic cleaning sink, a rinse station, an air dryer, and an inspection station equipped with a laser scanner for the detection of light-scattering centers on a wafer. The recirculation-filtration system is operating satisfactorily. The preliminary data on wafer cleaning and rinsing indicate that the design criteria of cleaning ability, chemicals usage, ease of operation, and safety have been largely met. Fu… more

Mulled coal: A beneficiated coal form for use as a fuel or fuel intermediate

Description: Energy International is developing a technology that will create a staged formulation with the first coal form (Mulled Coal) that can be stored, transported, and pumped. Just prior to combustion, the Mulled Coal (MC) would be modified to provide the properties needed for proper atomization. This concept is an alternative to the expensive and energy intensive thermal drying processing of fine coal wet cakes. The material is suitable for both direct feed use in conventional and fluid bed combusto… more

An analysis of the commercialization of eight conservation technologies

Description: The Office of Industrial Programs (OIP) of Battelle Pacific Northwest Laboratories has a long history of developing commercially successful technologies. This success is based on OIP's efforts to involve industry early in the technology development process and on the use of highly skilled technical staff. However, even the most technically successful products can fail to achieve widespread market acceptance. The objective of this work is to determine why some OIP-sponsored technologies are not … more

Synthesis and Characterization of Porous Hydroxyapatite and Hydroxyapatite Coatings

Description: A technique is developed to construct bulk hydroxyapatite (HAp) with different cellular structures. The technique involves the initial synthesis of nanocrystalline hydroxyapatite powder from an aqueous solution using water-soluble compounds and then followed by spray drying into agglomerated granules. The granules were further cold pressed and sintered into bulks at elevated temperatures. The sintering behavior of the HAp granules was characterized and compared with those previously reported.

EFFECT OF MECHANICAL CONDITIONING ON THIN-LAYER DRYING OF ENERGY SORGHUM (Sorghum bicolor (L.) Moench)

Description: Cellulosic energy varieties of Sorghum bicolor (L.) Moench show promise as a bioenergy feedstock, however, high moisture content at the time of harvest results in unacceptable levels of degradation when stored in aerobic conditions. To safely store sorghum biomass for extended periods in baled format, the material must be dried to inhibit microbial growth. One possible solution is allowing the material to dry under natural in-field conditions. This study examines the differences in thin-layer d… more

Drying/self-assembly of nanoparticle suspensions.

Description: The most feasible way to disperse particles in a bulk material or control their packing at a substrate is through fluidization in a carrier that can be processed with well-known techniques such as spin, drip and spray coating, fiber drawing, and casting. The next stage in the processing is often solidification involving drying by solvent evaporation. While there has been significant progress in the past few years in developing discrete element numerical methods to model dense nanoparticle dispe… more
