Stability Of Premixed H₂/O₂/N₂ Combusting Turbulent Jets, H. F. Nelson Oct 1977

Stability Of Premixed H₂/O₂/N₂ Combusting Turbulent Jets, H. F. Nelson

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

Experimental measurements and theoretical predictions of the stability of hydrogen-air-nitrogen premixed turbulent flames have been carried out. The turbulent flame is theoretically modeled using finite rate chemical kinetics and a well-stirred reactor. The model contains a free parameter, which is evaluated by comparing the theoretical predictions to experimental results. A hydrogen flame stability experiment was carried out and the results were compared to the theory. The theory and experiment were found to agree, if the free parameter in the theory varied as the reciprocal of the turbulent jet radius squared.

Assessing Environmental Costs Of Energy Procurement, Ronald G. Alderfer Oct 1977

Assessing Environmental Costs Of Energy Procurement, Ronald G. Alderfer

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

This paper describes an ecological approach to the assessment of environmental impact and associated costs of all major phases of energy procurement. The approach is based on identification of services performed and benefits offered by natural and man-modified ecosystems and requires that energy procurement activities be analyzed in terms of their impact on these services and benefits. A thorough cost assessment (including quantitative and qualitative factors) of alternate energy plans will aid both the selection of the most desirable alternate and the reduction of unforeseen costs and problems during and after construction .

Control Of Trace Elements During The Increasing Development Of Coal For Energy, Bobby G. Wixson, Ernst Bolter Oct 1977

Control Of Trace Elements During The Increasing Development Of Coal For Energy, Bobby G. Wixson, Ernst Bolter

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

The question of an energy crisis continues as many people in the United States have difficulty and become confused with what seems to be a continuing excess of gasoline, oil products and questionable reporting of price increases and profit margin by energy companies. However, the majority of the scientific and engineering community, knowledgable politicians and the general public realize that the energy crisis is real. Fortunately there still remains time to practice conservation and the development of alternative and new sources of energy if the United States can unite and implement a viable energy plan.

Regulatory Effectiveness In The Electric Utility Industry: An Empirical Analysis, Michael A. Zimmer Oct 1977

Regulatory Effectiveness In The Electric Utility Industry: An Empirical Analysis, Michael A. Zimmer

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

An established result in the theory of the regulated firm is that an effective rate-of-return constraint induces the firm to employ larger proportions of capital inputs to noncapital inputs than would be the case in the absence of the regulatory constraint. This overcapitalization, often referred to as the Averch-Johnson effect, has been the subject of several recent empirical studies of the electric utility industry. The present study adds to this body of literature. It seeks to test for the effectiveness of utility regulation in the context of a cost minimization model which includes the allowed rate of return as an …

Steam Raising With Low-Btu Gas Generators And Potential For Other Applications, Robert Owen Williams, John R. Goss, Brian C. Horsfield, Robert Hodam Oct 1977

Steam Raising With Low-Btu Gas Generators And Potential For Other Applications, Robert Owen Williams, John R. Goss, Brian C. Horsfield, Robert Hodam

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

A pilot plant gas producer was installed at a Walnut processing plant to recover usable energy from cracked walnut shell. The shell was converted to a low-Btu fuel gas (producer gas) and this was used to replace natural gas in a steam boiler. Longterm continuous operation of the producer has yet to be achieved due to mechanical inadequacies of the fuel feed and grate systems. These problems are a result of special fuel characteristics of walnut shell, which are being further investigated on a laboratory scale gasifier. It is expected that component changes and/or fuel preparation can facilitate satisfactory long …

Economic Optimization Of Heatpump Assisted Solar Heating In Illinois, Ali Shams, Edward A. Mass Oct 1977

Economic Optimization Of Heatpump Assisted Solar Heating In Illinois, Ali Shams, Edward A. Mass

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

This study undertakes the task of determing the optimal mix of solar and heat pump forms of heating. By installing a solar heating system a homeowner is considered to be an energy producer and thus to apply the least cost methods used by firms in the competitive market for any given level of fuel conservation. The study will examine the simulated performances of air and liquid circulating systems in conjunction with heat pumps, in parallel as well as combined fashion. Optimization is achieved by equating the present value of the cost of solar and heat pump heating systems at margin.

Economic Restraints On Reduced Energy Use In Agriculture, Lowell D. Hill Oct 1977

Economic Restraints On Reduced Energy Use In Agriculture, Lowell D. Hill

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

Many of the popular suggestions for improving energy use under mechanized agriculture would result in a reduction in total food supply or they are in conflict with economic decisions. This paper examines several of these suggestions and identifies the economic limits to their implementation. The choice of food products or techniques of production must be evaluated in the context of all uses of energy. Only a market system is capable of permitting every consumer to express his preferences for the infinite array of foods and energy uses.

Cost Effectiveness Of Bio-Gas Systems For Dairy Farms, J. C. Oppenlander, E. A. Cassell, R. N. Downer Oct 1977

Cost Effectiveness Of Bio-Gas Systems For Dairy Farms, J. C. Oppenlander, E. A. Cassell, R. N. Downer

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

Considerable attention has recently been focused on the development of farm management practices that utilize the total resource potential of animal wastes. In addition to the fertilizer value of manure, energy in the form of bio-gas can be generated from manure wastes by an anaerobic digestion process. The purpose of this economic analysis was to evaluate the feasibility of producing energy from the anaerobic digestion of dairy-cow manure. Anaerobic digestion systems were rationally designed for several farm management practices on Vermont dairy farms. These designs were sized to accommodate dairy herds of 20, 50, 100, and 200 cows for both …

A Strategy For Utilizing Nuclear Power, Edward J. Martens Oct 1977

A Strategy For Utilizing Nuclear Power, Edward J. Martens

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

One of our national goals is to achieve independence in the area of energy supplies in the next few years. We believe that attaining this goal will require extensive utilization of nuclear power in conventional fission reactors. We propose that the best way to develop our nuclear resource is through government ownership of the reactors. We argue that this will minimize the risks associated with the nuclear power option and clear the way for its exploitation.
