Book Description
The Resource Data Evaluation subtask of the US Department of Energy (DOE) base program represents an Energy and Environmental Research Center (EERC) initiative to promote the integration of geographic information system (GIS) technologies with other ongoing and planned EERC research in the areas of resource utilization, remediation, land use planning, and regulatory and policy assessment. Significant demand for GIS based information already exists for energy resource evaluation, interpretation of remote sensing data, environmental assessment at the state and local levels, and use in strategic planning. Through sound data taking procedures and wise data management policies, a GIS approach can serve an integral function in permitting cross disciplinary uses of information by many EERC researchers. The use of GIS methodologies will expand the potential for interaction between the researcher, governmental agencies, and private companies. The objective of this task was to determine the appropriate platform and approach upon which to develop GIS applications for optimizing resource evaluation and integrating this information with related areas of interest. Database design was undertaken for two EERC projects: coal occurrence in Bowman and adjacent counties in the Fort Union Coal Region of southwestern North Dakota; and energy resource utilization concerns for selected sites in Alaska related to energy consumption, gas fields, gas pipelines, and coal availability.

Book Description
In order to increase national energy self-sufficiency for the near future, energy systems will be required to fire low-grade fuels and use more efficient energy cycles than those available today. The steam cycle used at present is limited to a maximum steam temperature of 550°C and thus a conversion efficiency of 35%. To boost efficiency significantly, much higher working fluid temperatures are required, compelling subsystems to operate at much higher temperatures and, therefore, in much more corrosive environments than those currently used. Problems of special concern are corrosion and fatigue of direct-fired turbine blades, corrosion and blinding of hot-gas cleanup filters, catastrophic failure of high-temperature heat exchangers, and spalling and dissolution of refractory materials. The extreme conditions will require the use of advanced structural materials such as high-temperature ceramics for the construction of the subsystems. Unfortunately, little is known of the performance of these materials in actual coal combustion environments. Although some corrosion testing has been performed in the past, most has been done by groups experimenting with ash or slag stimulants composed of only one or two simple compounds. For this project performed at the Energy & Environmental Research Center (EERC), actual coal ash and slag will be used in simulated combustion conditions so that more realistic determinations of the mechanisms of corrosion can be made. The work includes three main research areas focusing on two fossil energy subsystems: high-temperature heat exchangers and hot-gas cleanup filters. The first area involves developing existing abilities in thermodynamic equilibrium calculations to determine the most appropriate corroding agents to include in the tests; the second area involves coal slag corrosion of high temperature heat exchangers; and the third, lower-temperature ash and gas corrosion hot-gas cleanup filters.
