These studies show the feasibility of a one-stage, air blown, fluid bed MSW conversion system.

Burning Wood As A Supplement To Solid Waste, Andrew R. Banta, William P. Smith

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

The University of Kansas at Lawrence uses natural gas and oil to generate steam for heating and other campus needs. The projected price increase of these fuels has led to a study of burning solid waste and wood. This study discusses the technical and economic considerations of burning wood. Topics included are sources and availability, collection and transportation, preparation and burning, and environmental effects. It is concluded that sufficient wood is available; truck transport is the only feasible option; drying some wood is desirable; and that the burning can be done separately or directly with the solid waste.

New Concept In Louver Blade Design Reduces Energy Losses, Peggy Kitchen, R. David Moore

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

A new louver blade design, developed through extensive wind tunnel tests, employs an airfoil shape with excellent aerodynamic characteristics. Stressed-skin construction adds strength and rigidity permitting the use of longer blades and the elimination of unnecessary frame sections. Lever arms and linkage rods are placed out of the airstream, further reducing resistance to airflow. Louvers and dampers employing this design will have a pressure drop of from 1/4 to 1/10 that of units of traditional design.

An Analysis Of Solar Heating Costs In Arkansas Broiler Houses, Ralph Gunderson, J. Martin Redfern

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

This study is based on the computer simulation model of a solar heated broiler house in four locations in Arkansas. This simulation model estimated the annual energy savings in each broiler house due to the installation of a solar heating system. This paper uses present value analysis to estimate the life cycle costs of heating conventional and solar heated broiler houses in the state of Arkansas. From these calculations, the number of years required to achieve a break-even cost of heating is estimated.

The Development Of Coal-Based Emulsions And Their Potential Impact On The National Economy, Murphy I. Song

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

The proposed national energy policy emphasizes the use of coal replacing oil and gas. Coal-oil mixture (COM) can be produced using techniques developed in recent years to replace oil and gas. Large existing utility and industrial boilers could be converted to bum COM by retrofitting the boilers. In addition, the COM provides definite financial advantages to the owners of large utility and industrial boilers. The use of COM impacts on the national economy through new investment for retrofitting utility and industrial boilers, through reduced importation of residual oil, and through increased demand for coal.

Usable Energy Resources Expand Under The Economic Pressures Of Fuel Scarcity, Raphael Shen

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

Until mankind finds properties in materials that are useful and usable under given economic conditions, these materials are not resources. In the past, many of them became usable as the ones they replaced became scarce and expensive. Market induced R & D toward profit seeking and cost minimization hastens to incorporate currently unused materials into the productive processes. With the increase in oil and natural gas prices, hitherto untapped energy sources present themselves as attractive alternatives. There will be no permanent shortage of energy resources, and the current energy crisis will be a page of past history in the foreseeable …

The Formation And Decomposition Of Nickel Carbide In Evaporated Nickel Films On Graphite, S. Sinharoy, L. L. Levenson

Physics Faculty Research & Creative Works

Auger electron spectroscopy and X-ray photoelectron spectroscopy were used to study nickel carbide (Ni3C) formed during the evaporation of nickel onto the surface of single-crystal graphite. It is shown that Ni3C formed in this manner extends from the surface to close to the interface. A model is proposed to explain the mechanism of Ni3C formation. The 1s photoelectron peak from Ni3C is observed to have a binding energy 0.6 eV lower than that of pure graphite. This is attributed to the lack of any significant ionic bonding in Ni3C. © 1978.

Angular Differential Cross Sections For 25-, 50-, And 100-Kev-Proton Excitation Of Helium To The N=2 Level, John T. Park, Jacob M. George, Jerry Peacher, Judith E. Aldag

Physics Faculty Research & Creative Works

Differential cross sections for 25-, 50-, and 100-keV-proton excitation of helium to the n=2 level have been determined for center-of-mass scattering angles from 0 to 1.2 mrad. The cross sections were obtained from an analysis of the angular distribution of the scattered protons which had lost an energy corresponding to the excitation of the helium target to its n=2 level. The differential cross section is very sharply peaked in the forward direction and decreases by a factor of 45 in 1.0 mrad at 25 keV and by a factor of 650 in 1.0 mrad at 100 keV. The data are …
