A suggestion is made that electric utility furnaces with their high temperature and reliable operation might be used to safely destroy certain hazardous wastes. Other hazardous wastes may have to be carefully excluded from planned refuse derived fuel projects.

RoemmcR Burner: High Ash Solid Fuel Combustion System, John L. Stafford

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Many solid waste disposal problems have been lately recognized as fuel sources. Few of these potential fuels are normally available in a clean (low ash), dry state, and those that do demand premium price. The ROEMMCr Burner system provides fuel preparation (drying and size reduction) and combustion with dry ash separation (no slag). Technologies developed for earlier solid combustion systems are combined with inertial separation of solid-gas mixtures and applied to the energy recovery from inexpensive solid residue. Operational performance data are presented.

Energy Conservation Opportunities For Residential Buildings, Jerold W. Jones

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Residential energy use represents 22% of our national energy consumption. A number of recent studies have indicated that this use could be reduced by 30% without adversely affecting occupant comfort or convenience. Thus, there is increasing emphasis on the implementation of conservation measures in the residential sector. However, the majority of homeowners are still unable to confidently determine which of the many conservation options available will provide a reasonable return on their investment and significantly reduce their energy consumption. Consumers have been confronted with criticism for the use of small electric appliances at one extreme and overzealous promises as to …

Agronomic Potential For Biomass Production, C. J. Nelson

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Plant biomass may be an economic means of harvesting and storing solar energy. present day agricultural practices, however, do not allow maximum biomass production in the primary sense, or as crop residue. Biomass production is closely related to photosynthetic potential of single leaves in a complete canopy. New developments in crop selection and culture may allow more efficient canopies and photosynthetic rates. Genetic improvement in vegetative growth as well as grain or economic product would increase production potential for both fuel crops and crop residues. Long range agronomic considerations on also need to be considered.

The Forgotten Fundamentals Of The Energy Crisis, Albert A. Bartlett

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Papers at an energy conference may tend to deal with details. The details are important, but only if they relate to the national or global picture. We know that an energy crisis has motivated us to look at all manner of detail in regard to our own particular uses of energy. We hear political leaders of the United States speaking of "energy self-sufficiency" and of "Project Independence". We have the vague feeling that arctic oil from Alaska will relieve the energy crisis, and we are told that the United States is in good shape in the long run because of …

World Oil Supplies And The Next 25 Years, J. A. Eyer

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Petroleum must become a more efficiently used commodity while alternative energy sources are developed, but it will remain in high demand as long as the world wide availability is assured, regardless of the influence of the O.P.E.C. nations. The availability of petroleum on a country-by-country survey shows clearly that there are large known recoverable reserves as well as large potential for discovering added reserves. However, the highly industrialized nations do not have adequate petroleum supplies and this will probably not change as long as petroleum remains as the primary energy source.

Rail Transportation Systems That Help Us Meet Our Energy Requirements, Alvin J. Hurt Jr.

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

In direct relation with Economics of Energy, Energy and Power Systems, and Energy Management is transportation of potential energy. Within the scope of the United States energy movement, the railroads play and will continue to play a vital role, since coal is our major energy source for the present as well as for the future.

The only way these huge amounts of coal can be moved over our railroad network is through the establishment of a "System's Approach to transportation and handling of bulk material.

This paper will discuss these existing systems as well as expected improvements.

Application Of Special Fluidized Bed Techniques To Coal Gasification, Gary Kent Patterson

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The properties of fluidized beds can be drastically altered by the insertion of various types of internal structures. These include screens of all types and orientations, baffles both horizontal and vertical, and heat transfer surfaces. Experimental studies of certain of these internals have been carried out at UMR with the aim of improving the quality of the fluid bed. By improved quality is usually meant smoother, better controlled fluidization, minimized slugging, improved gas-solid contacting, increased or smoothed heat or electrical conduction, and control of the solids movement pattern.

What has been learned at UMR, particularly with difficult to fluidize materials, …

The Tradeoffs Between Energy Conversion Stages, Environmental Effects, And Technical Efficiency, Angelos Pagoulatos

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

From analyzing the physical constraints in managing exhaustible and nonrenewable energy resources it follows that decisions concerning how far to convert a given energy resource should be made within an economic framework. The tradeoffs between conversion stages, environmental effects, technical efficiency and uses satisfied by energy resources are then determined. In light of the direct and opportunity costs stemming from increased conversion stages, the intertemporal allocative decisions for exhaustible and nonrenewable energy resources are derived.

The Demand And Supply Of World Petroleum And Its Consequences For Agricultural Economic Development, Amalia Vellianitis-Fidas

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The concerns related to the increase cost of petroleum in 1974 and 1975 centered around the enormous transfer of funds needed to pay for petroleum imports by most countries. Although this transfer is successfully taking place in the developed countries, it is taking place with serious long run external financial consequences for the less developed countries. In addition, these countries' continued agricultural development will probably depend on finding new paths to agricultural efficiency that are not as dependent on high-priced fuels.

Results and analyses of remotely sensed data taken from a NASA aircraft are reported. The study uses continuous data taken in the 8-14ym region of the infrared spectrum which is directly related to surface temperature. The analysis is concentrated on the micrometeorological effects of lakes and hills during near freezing conditions. The impetus for the study is an economic one since proper selection of a site for certain freeze susceptible crops, such as citrus, can result in huge savings of energy and resources.

The Status Of And Need For New Coal Gasification Technology, Jimmie R. Bowden

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Movement toward a domestic coal-based energy policy has been barely perceptible since the Arab oil embargo of 1973-4. Rapidly declining supplies of natural gas for small businesses and residential uses can be supplemented by coal gasification or replacement of gas by coal as a power generating fuel. At this time it probably is the better choice to use coal to generate power instead of gas. Second generation coal gasification processes under development with ERDA financial help will not change this balance in the next 10 years if at all.
