SRC-Water Slurry Rheology. Final Technical Report

Description: SRC-water slurries exhibit properties that qualify them for use as fuel in conventional oil-fired combustion facilities. However, to date, the slurries tested have shown storage instability, which requires constant agitation and recirculation to avoid sedimentation in the storage tanks. High viscosities of the material being evaluated hampered the test performance. A program was instituted to better understand the variables responsible for viscosity and static stability of these slurries. Effec… more

Feasibility of utilizing a rotating fluidized bed for the removal of sulfur from hot gases. Progress report

Description: The RFB provides an option for coal combustion systems by separating the desulfurization of hot combustion product gases from the combustion process itself. Fluid-bed combustors conventionally combine the two processes and, as a result, the rapid combustion process is carried out in equipment whose design is dominated by the requirements of the slower and temperature-specific desulfurization process. Neither process can be optimized and, in fact, the specifics of the combined reaction chemistry… more

Condensing economizers for small coal-fired equipment

Description: Condensing economizers can be used to increase the thermal efficiency of boilers and furnaces. This study focuses on evaluating indirect contact economizers as applied to heating equipment burning coal-water mixtures although the results can be extended to other fuels. In addition to dry gas sensible heat, latent heat is recovered from flue gas water vapor, improving system efficiency markedly. In addition to improving thermal efficiency, condensing economizers can also capture particulates. In… more

Synthetic fuel aromaticity and staged combustion

Description: Samples of middle and heavy SRC-II distillates were distilled into 50 C boiling point range fractions. These were characterized by measurements of their molecular weight, elemental analysis and basic nitrogen content and calculation of average molecular structures. The structures typically consisted of 1 to 3 aromatic rings fused to alicyclic rings with short, 1 to 3 carbon aliphatic side chains. The lower boiling fractions contained significant amounts (1 atom/molecule) of oxygen while the hea… more

Advanced atomization concept for CWF burning in small combustors, Phase 2

Description: The program describes a concept referred to as opposed-jet atomization, which is particularly applicable to coal-water fuel (CWF). In the present atomizer design, two opposed jets of CWF are directed at each other and externally encounter a perpendicular blast of air at the collision point to create a spray of much finer droplets. The present Phase 2 program involved further evaluation of the opposed-jet atomizer performance and related tasks.
