The Industrial Fuel Gas Demonstration Plant Program (MLGW/DOE), Contract ET-77-C-01-2582, has been slowed due to lack of an adequate data base for demonstration plant design. This design data base is to be developed by Institute of Gas Technology (IGT) at their U-GAS pilot plant. While initial data and operating results from the pilot plant have been encouraging, ash-balanced operation with coal using the technique of ash agglomeration has proven to be more difficult than originally envisioned. Ash must be removed from the gasifier at the same rate as it is being fed to achieve overall ash balance. Adequate ash balance has been achieved by bed withdrawal, but in order to attain high levels of carbon utilization, preferential removal of high-ash material from the gasifier will be required. It is the conclusion of all parties involved that the operating parameters necessary to achieve ash balance and high carbon utilization must be demonstrated at the pilot plant level before a full scale demonstration plant design effort is started. IGT, with guidance from the program Steering Committee and assistance from the Technical Sub-Committee has re-evaluated its efforts under Task IX, Technical Support. With a critical assessment of data generated to date and an …

This document is the second of a two-volume Overall Program Plan for rescheduling Task IX (Technical Support) of the Industrial Fuel Gas Demonstration Plant Program (MLGW/DOE), Contract ET-77-C-01-2582. Volume I presents the schedule and organization for carrying out the overall plan which is divided into three major tasks: Bench Scale Tests, Cold-Flow Model Studies, and Pilot Plant Operations. This volume, Volume II, gives a more detailed presentation of the test objectives and procedures for the most important part of the plan, Pilot Plant Operations. The objective of Volume II is to provide a systematic approach to obtain high carbon conversion under steady-state, ash agglomerating conditions with coal in the U-GAS pilot plant. This will allow the achievement of the principal goal of pilot plant operations, that is, to obtain data for the design of the U-GAS demonstration plant. The test program for pilot plant operations has been formulated with the assistance of the Technical Subcommittee which has members from all the parties involved in the Industrial Fuel Gas Demonstration Plant Program, namely, Memphis Light, Gas and Water Division, Department of Energy, Foster Wheeler Energy Corporation, Delta Refining Company, Institute of Gas Technology, and Monsanto Research Corporation.

The performance and cost-effectiveness of three photovoltaic total energy system concepts designed to meet the thermal and electrical demands of a typical single family house are compared. The three photovoltaic total energy system concepts considered are: (1) All-photovoltaic systems. Passively air-cooled photovoltaic panels provide electricity to meet both electrical and thermal demands. (2) Separate-panel systems. Solar thermal panels provide thermal energy, while passively air-cooled photovoltaic panels serve the purely electric demand. (3) Combined thermal/electric panel systems. Water-cooled photovoltaic panels provide both thermal energy (transported by cooling water) and electrical energy to meet the separate thermal and electrical demands. Additional passively air-cooled photovoltaic panels are added, as required, to meet the electrical demand. The thermal demand is assumed to consist of the energy required for domestic hot water and space heating, while the electrical demand includes the energy required for baseload power (lights, appliances, etc.) plus air conditioning. An analysis procedure has been developed that permits definition of the panel area, electrical and/or thermal storage capacity, and utility backup energy level that, in combination, provide the lowest annual energy cost to the homeowner for each system concept for specified assumptions about costs and system operations. The procedure appears capable of being …

The state of stress in the crust of the earth is of great fundamental and practical significance. No totally satisfactory method for measuring the complete state of stress has been devised yet. Despite this, many efforts have been made to measure this state of stress at different locations. From a compilation of many of the results, fifty which yielded the complete state of stress and in which one of the principal stresses is vertical, have been selected for a statistical analysis in an endeavor to define the nature of the state of stress in the crust. These data have been analyzed as a whole, and divided into three groups depending upon whether the vertical stress is the maximum, minimum or intermediate principal stress. Linear regression analyses of the values of half the maximum stress difference as a function of half the sum of the maximum and minimum principal stresses have been made. The correlation coefficients for these fits are 0.786 for the data as a whole and 0.848, 0.790 and 0.383 for each of the groups. Values of the coefficient of sliding friction between blocks of rock comprising the crust, interpreted from the slopes of these lines, ranged from 0.625 …

The purpose of the symposium was to review the current status of the concentrating collector technology, to disseminate the information gained from experience in operating solar systems, and to highlight the significant areas of technology development that must be vigorously pursued to foster early commercialization of concentrating solar collectors. Separate abstracts were prepared for thirteen invited papers and working group summaries. Two papers were previously abstracted for EDB.

The roles of each type of experiment in establishing uniquely the values of the the neutral-current couplings of u and d quarks are analyzed together with their implications for gauge models of the weak and electromagnetic interactions. An analysis of the neutral-current couplings of electrons and of the data based on the assumption that only one Z/sup 0/ boson exists is given. Also a model-independent analysis of parity violation experiments is discussed. 85 references. (JFP)

The solar-related activities undertaken by the Northwest states of Oregon, Idaho, Washington, and Montana are detailed. Finally, roles are addressed which municipal government may play either to encourage or to deter the widespread use of solar heating systems. (MHR)

Simulation studies have recently been made of the Krafla Geothermal Field in Northern Iceland. The field is close to boiling in the formation at depths of 1800 meters and below. Two simulations were undertaken. The first studied radial flow, i.e., behavior around a production well. It was found that the relative permeability distribution of the liquid and vapor phase had very little effect on the general results. The simulation shows that while the well produced superheated steam after a few days of production, the superheated front moved only 1/10 the distance of the boiling front, which extended to a radial distance of over 200 meters after one-half year production. The second simulation investigated the two-zone system which is believed to exist in Krafla. This study simulated one well producing 50 kg/s from both zones for a period of 33 years. It showed that boiling in the formation begins near the production well and at the connection between the two zones. After 20 years, boiling takes place in the entire lower zone region with saturation (steam volume fraction) ranging from 0-30 percent. After 33 years, saturation increased to over 60 percent at the top of the lower zone, just under the …

This assessment of Economic Incentives to Wind Systems Commercialization is an analysis of the quantitative and qualitative impacts of a variety of Government funded economic incentives on Wind Energy Conversion Systems (WECS). The purpose of this study is to achieve better understanding of the relationship between implementation of specific economic incentives for WECS, and the factors surrounding WECS commercial introduction.

The viscosity of glass melts containing four simulated sludge types and two frit candidates (Frits 18 and 21) was measured over the temperature range 750 to 1200/sup 0/C. The viscosity of melts made with either frit was reduced by the addition of high iron sludge, unchanged by average sludge, and increased by composite and high aluminum sludge. High aluminium sludge greatly increased the viscosity. Frit 21 (containing 4 wt % Li/sub 2/O substituted for 4 wt % Na/sub 2/O in Frit 18) was clearly better than Frit 18 in terms of its low viscosity. However, further reductions in viscosity are desirable, especially for glasses containing high aluminum sludge. Changing any frit component by 1 wt % did not significantly affect the viscosity of the glasses. Therefore, variability of 1 wt % in any frit component can be tolerated.
