FUNDAMENTAL CHARACTERIZATION OF EMERGING FBC AND FGD WASTES. In this project, wastes from fluidized bed combustion and flue gas desulfurization are analyzed for potential toxicity and evaluated for use in concrete products. PIs: Robert Dawson and Carol Kilgour.

DEVELOPMENT OF A RADIO FREQUENCY SURFACE CONTOUR MAPPING SYSTEM. A radio frequency (i.e., radar)-based system to remotely monitor and map the surfaces of process streams in a variety of coal processing vessels (e.g., FBC's, gasifiers, storage silos) is being developed. PIs: Warren Straszheim and Robert Weber.

ON-LINE MONITORING OF MERCURY AND HYDROGEN CHLORIDE IN HOT GASES FROM COAL GASIFIERS. In this project, on-line monitors suitable for determining mercury and hydrogen chloride in high-temperature, high-pressure gases from coal gasification systems are developed and tested. PI: Glenn Norton.

LEACHING OF SPENT LIMESTONE SORBENT MATERIALS. The goal of this work is to determine the amounts and types of reduced sulfur species present in spent sorbents released during leaching of limestone sorbent ashes produced by selected coal conversion and utilization technologies. PI: Colin Chriswell.

ALKALI MONITORING FOR PC-FIRED STEAM GENERATION. A specialized on-line monitor developed at Ames is being modified for application to advanced coal-based designs for high performance power-generation systems. PI: David Eckels.

ADVANCED CONCEPTS FOR CONTROL OF FINE PARTICULATES IN COAL COMBUSTION. Novel concepts based on the use of sonic energy to improve existing technologies for controlling ash deposition, improving hot filtration, and minimizing the associated corrosion of advanced materials used in coal combustion are developed and demonstrated. PI: Bogdan Slomka.

INTEGRATED GASIFICATION/FUEL CELL POWER SYSTEM. The goal of this work is to develop a research capability in the rapidly emerging area of power generation via molten carbonate fuel cells (MCFC). Special emphasis is placed on the use of producer gas from coal or biomass gasifiers as fuel supply for MCFC. PI: Robert Brown.
