Bates solar industrial process steam application environmental impact assessment (open access)

Bates solar industrial process steam application environmental impact assessment

It is planned to install 34,440 square feet of linear parabolic trough solar collectors at a new corrugator plant for making corrugated boxes. The system is to operate in parallel with a fossil fuel boiler. An assessment is presented of the impacts of the solar energy system on the existing environment and to determine whether or not a more detailed environmental impact statement is needed. The environmental assessment is based on actual operational data obtained on the collector, fluid, and heat transport system. A description of the design of the solar energy system and its application is given. Also included is a discussion of the location of the new plant in Fort Worth, Texas, and of the surrounding environment. Environmental impacts are discussed in detail, and alternatives to the solar industrial process steam retrofit application are offered. It is concluded that the overall benefits from the solar industrial process heat system outweigh any negative environmental factors. Benefits include reduced fossil fuel demand, with attending reductions in air pollutants. The selection of a stable heat transfer fluid with low toxicity and biodegradable qualities minimizes environmental damage due to fluid spills, personal exposure, and degradation byproducts. The collector is found to be …

Coal as an option for power generation in US territories of the Pacific (open access)

Coal as an option for power generation in US territories of the Pacific

A survey of general considerations relating to the use of coal in US territories and trust territories of the Pacific suggests that coal is a viable option for power generation. Future coal supplies, principally from Australia and the west coast of America, promise to be more than adequate, but large bulk carriers will probably not be able to land coal directly because of inadequate port facilities. Hence, smaller than Panamax-class vessels (60,000 dwt) or some arrangement utilizing self-loading barges or lighters would have to be used. Except for Guam, with peak power requirements on the order of 175 MW/sub e/, most territories have current, albeit inadequate, installations of 1 to 25 MW/sub e/ Turnkey, conventional-coal-fired, electrical-power generating systems are available in that size range. US environmental laws are now applicable to Guam and American Samoa; the trust territories are exempt. However, the small power requirements of many small islands will qualify for exemption from the New Source Performance Standards called for in the Clean Air Act. The principal problems with coal use in the territories, apart from the shallow draft of most harbors, are the limited amount of land available and the high capital costs associated with conversion.

Study of the competitive viability of minority fuel oil marketers. Final report (open access)

Study of the competitive viability of minority fuel oil marketers. Final report

Previous studies on the competitive viability of the fuel oil heating market had addressed some of the unique problems facing minority fuel oil marketers (MFMs) within the total market sector (TMS). This study focused on identifying and developing quantitative information on MFMs in the TMS. The specific objective was to determine whether the business problems experienced by MFMs were directly related to their minority status or were characterstic of any firm in the TMS operating under comparable conditions. As an overall conclusion, thorough investigation of the MFMs considered to constitute the universe of minoriy firms within the TMS did not reveal any evidence of overt discrimination affecting the competitive viability of MFMs. Upon analysis, the problems reported by MFMs could not be reasonably ascribed to discrimination on the basis of their minority business status. The study, however, did point up problems unique to MFMs as the result of typical operational and financial characteristics. For example, MFMs, compared to the TMS norm, have not been in the market as long and are smaller in terms of total assets, number of employees, number of trucks, number of accounts and annual volume of oil delivered. Their primary customers are low-income families in urban …

Comparative analysis of LMFBR licensing in the United States and other countries - notably France. Executive summary (open access)

Comparative analysis of LMFBR licensing in the United States and other countries - notably France. Executive summary

The safety-related design aspects and licensing experiences of LMFBR projects in other democratic countries have been studied and contrasted to those in the United States in order to understand the importance of different approaches to safety, and also to understand better the system of the United States. The regulatory systems and LMFBR programs of France and the United States are contrasted in detail, and that of West Germany is also studied. The programs of Japan and the United Kingdom receive considerably less attention, and that of the Soviet Union is ignored.

Biological and clinical dosimetry. Progress report, October 1, 1980-September 30, 1981

A second measurement of the event size distribution for 20 MeV neutrons was carried out at Ohio University to determine the reproducability of results. Again a significant difference between measurement and theoretical calculations by Caswell and Coyne was found. The measured fraction of events due to alpha particles was significantly lower than that predicted by the calculation of Casell and Coyne. Furthermore, the discrepancies with the theoretical calculations made by Caswell and Coyne were confirmed by measurements made with a differently designed T-E proportional counter. A non-isolated-sensor solid polystyrene calorimeter was constructed and tested during the past year. It has the advantages of, (1) simple construction, (2) simple operation, without vacuum or feedback for temperature control, (3) the capability of obtaining simultaneous measurements at different depths and azimuthal angle, and (4) the possibility of obtaining measurements with the calorimeter directed in any orientation.

Characterization of the dynamic roadway-powered electric-vehicle system (open access)

Characterization of the dynamic roadway-powered electric-vehicle system

The measurements, data reduction, and analysis contained herein are for the most part preliminary. The instrumentation system for dynamic measurements was not completed and so the measurements taken were in the static mode and a limited amount of instruments was used. Most of these preliminary measurements were made to characterize the losses in the roadway and the pickup of the dynamic RPEV system. By analysis of power, voltage, current and impedance-bridge measurements (at 100 Hz and 1000 Hz), the equivalent series resistance (ESR) and equivalent parallel resistance (EPR) of the roadway and pickup inductances and capacitances were derived. Separation of the inductive and capacitive losses was difficult because of the large ratio of stored energy to power loss, that is, the Q of each of these system elements, and the separation was accomplished by modeling the system losses and making a least-squares fit to the model with the test data. The bridge data was used primarily for capacitance and inductance values and the ESR or EPR data were not analyzed.

Flux of energy and essential elements through the continental shelf ecosystem. Progress report (open access)

Flux of energy and essential elements through the continental shelf ecosystem. Progress report

There are three distinct but not mutually exclusive areas of research in this contract, studies of intrusions of the west wall of the Gulf Stream onto the outer continental shelf, studies of the flux of materials across nearshore density fronts, and advances in understanding of the planktonic food web of the continental shelf. Studies of frontal events on the outer and inner continental shelf involve distinctive physical and chemical regimes and have proven to require distinctive biological approaches. The studies of the food web run through our work on both of the frontal regimes, but certain aspects have become subjects in their own right. We have developed a simulation model of the flux of energy through the continental shelf food web which we believe to be more realistic than previous ones of its type. We have examined several of the many roles of dissolved organic compounds in sea water which originate either from release by phytoplankton, digestive processes or metabolites of zooplankton, or extracellular digestion of microorganisms. Methods have been developed under this contract to measure both the chelating capacity of naturally occurring organic materials and the copper concentration in the water. It has been possible to characterize the effects, …

Underground home A/C system. Final report

The purpose of the project was to transfer the heat of house air into the earth through an underground piping system, return the cooler to the house and disperse it throughout the house. The principle of the idea has been achieved, but not to the extent desired. It was originally hoped that the system would allow temperatures in the house to reach a maximum of 80/sup 0/ even during days where outside temperatures reached high 90/sup 0/. So far, a differential of 6/sup 0/ to 8/sup 0/ has been achieved.

Effect of solid particles on the turbulent flow of a round gaseous jet. A mathematical and experimental study. Quarterly technical progress report, May 1, 1981-October 30, 1981

Progress in mathematical and experimental studies aimed at modeling and measuring flows rates for the two-phase gases with dispersed particles turbulent flows in jets is reported. Exact transport equations of mass and momentum for the two phases, the carrier fluid's kinetic energy of turbulence and its dissipation rate have been derived for incompressible two-phase flows. The modeling of the various turbulence correlations has been completed. The finite-difference formulation of the equations is in progress at present. An outline of the work completed so far is described in the next section. In the area of clear air jet measurements, attempts were made to obtain two-dimensional measurements of clear air jet using a two-color, bragg cell shifted laser velocimeter. A complete data set for the streamwise component of mean velocity and turbulence intensity and some data for tangential velocity components were recorded and are included. These data were obtained using a recently modified software package for two-component data acquisition. In the process of the experiment, some software/hardware problems evolved which resulted in incorrect values for shear stress data as well as the tangential velocity samples. The hardware and the software for the coincidence requirement of the two components were modified and the …

Spheromak reactor-design study

A general overview of spheromak reactor characteristics, such as MHD stability, start up, and plasma geometry is presented. In addition, comparisons are made between spheromaks, tokamaks and field reversed mirrors. The computer code Sphero is also discussed. Sphero is a zero dimensional time independent transport code that uses particle confinement times and profile parameters as input since they are not known with certainty at the present time. More specifically, Sphero numerically solves a given set of transport equations whose solutions include such variables as fuel ion (deuterium and tritium) density, electron density, alpha particle density and ion, electron temperatures.

Analytical approach for confirming the achievement of LMFBR reliability goals (open access)

Analytical approach for confirming the achievement of LMFBR reliability goals

The approach, recommended by GE-ARSD, for confirming the achievement of LMFBR reliability goals relies upon a comprehensive understanding of the physical and operational characteristics of the system and the environments to which the system will be subjected during its operational life. This kind of understanding is required for an approach based on system hardware testing or analyses, as recommended in this report. However, for a system as complex and expensive as the LMFBR, an approach which relies primarily on system hardware testing would be prohibitive both in cost and time to obtain the required system reliability test information. By using an analytical approach, results of tests (reliability and functional) at a low level within the specific system of interest, as well as results from other similar systems can be used to form the data base for confirming the achievement of the system reliability goals. This data, along with information relating to the design characteristics and operating environments of the specific system, will be used in the assessment of the system's reliability.

CaO interactions in the staged combustion of coal. First quarterly technical progress report for the period September 23-December 31, 1980 (open access)

CaO interactions in the staged combustion of coal. First quarterly technical progress report for the period September 23-December 31, 1980

It is widely recognized that alkaline oxides, especially CaO, can be most effective in capturing sulfur in-situ. It is equally well recognized that NO/sub x/ emissions due to fuel-bound nitrogen in coal can be effectively minimized with staged combustion. Both these aspects have been demonstrated separately at Battelle and other laboratories. It is the overall objective of this program to develop the basis for optimizing sulfur capture by CaO under staged combustion. Our approach to accomplishing this goal is via an experimental and interpretative study of the chemistry and interactions of CaO under simulated and actual staged combustion conditions. In staged combustion one fires first under reducing (fuel rich) conditions prior to oxidation in the second stage. Our studies wherein coals were treated with CaO, i.e., impregnated with CaO for pulverized coal firing, or mixed and pelletized with CaO for stoker firing, suggest that conditions prevail under which CaO is first converted to CaS prior to being oxidized to CaSO/sub 4/. Since CaS has a greater thermal stability than CaSO/sub 4/, it is therefore possible to fire at temperatures above 900/sup 0/C (1650/sup 0/F) and retain sulfur under proper stoichiometric conditions. The program is aimed at defining the chemistry and …

Laboratory/bench-scale testing and evaluation of the A. P. T. Dry-Plate Scrubber. Fourth quarterly technical progress report, December 1, 1980-February 28, 1981 (open access)

Laboratory/bench-scale testing and evaluation of the A. P. T. Dry-Plate Scrubber. Fourth quarterly technical progress report, December 1, 1980-February 28, 1981

The A.P.T. Dry Plate Scrubber (DPS) uses a shallow, dense mobile bed of solid collector granules which move across a perforated plate. The gas stream containing fine particles and vapors is moved upward through the perforations to form high velocity gas jets. The fine particles are removed by inertial deposition onto the collector granules or by direct interception. Electrostatic forces also can be used to improve the collection efficiency and increase the adhesive forces between the particles and collectors. The DPS column consists of a series of collection stages (perforated plates) with the collectors either passing sequentially over each stage or being fed separately to each stage. The stages can be designed so as to promote the collection of large particles on the lower stages and the collection of fine particles and alkali vapors on the upper stages. The DPS is especially well suited for cleaning high temperature and pressure gases such as the effluent from a pressurized fluidized bed combustion (PFBC) process. The objective of this project is to conduct a bench scale experimental evaluation of the DPS at high temperature and pressure to determine its potential for controlling particulate and alkali vapor emissions from PFBC processes.

Methods for evaluating and ranking transportation energy conservation programs. Final report

Methods for comparative evaluations of the Office of Transportation programs designed to help achieve significant reductions in the consumption of petroleum by different forms of transportation while maintaining public, commercial, and industrial mobility are described. Assessments of the programs in terms of petroleum savings, incremental costs to consumers of the technologies and activities, probability of technical and market success, and external impacts due to environmental, economic, and social factors are inputs to the evaluation methodologies presented. The methods described for evaluating the programs on a comparative basis are three ranking functions and a policy matrix listing important attributes of the programs and the technologies and activities with which they are concerned and include the traditional net present value measure which computes the present worth of petroleum savings less the present worth of costs. This is modified by dividing by the present value of DOE funding to obtain a net present value per program dollar, which is the second ranking function. The third ranking function is broader in that it takes external impacts into account and is known as the comprehensive ranking function. Procedures are described for making computations of the ranking functions and the attributes that require computation. Computations are …

Silicon materials task of the Low-Cost Solar Array Project: Phase IV. Effects of impurities and processing on silicon solar cells. Twenty-first quarterly report, October-December 1980 (open access)

Silicon materials task of the Low-Cost Solar Array Project: Phase IV. Effects of impurities and processing on silicon solar cells. Twenty-first quarterly report, October-December 1980

The overall objective of this program is to define the effects of impurities, various thermochemical processes, and any impurity-process interactions upon the performance of terrestrial solar cells. The results of the study form a basis for silicon producers, wafer manufacturers, and cell fabricators to develop appropriate cost-benefit relationships for the use of less pure, less costly solar grade silicon. Cr is highly mobile in silicon even at temperatures as low as 600/sup 0/C. Contrasting with earlier data for Mo, Ti, and V, Cr concentrations vary from place to place in polycrystalline silicon wafers and the electrically-active Cr concentration in the polysilicon is more than an order of magnitude smaller than would be projected from single crystal impurity data. We hypothesize that Cr diffuses during ingot cooldown after groth, preferentially segregates to grain boundaries and becomes electrically deactivated. Both Al and Au introduce deep levels when grown into silicon crystals. Accelerated aging data from Ni-contaminated silicon imply that no significant impurity-induced cell performance reduction should be expected over a twenty-year device lifetime. Combined electrical bias and thermal stressing of silicon solar cells containing Nb, Fe, Cu, Ti, Cr, and Ag, respectively produces no performance loss after 100 hour exposures up to …
