(Pulsed atmospheric fluidized-bed combustion). [Installation of the pulsed atmospheric fluidized-bed combustion components]
This second Quarterly Technical Progress Report presents the results of work accomplished during the period July 25 through October 30, 1988. The overall objective of the program is the development of a pulsed atmospheric fluidized-bed combustion (PAFBC) technology to burn coal and to provide heat and steam to commercial, institutional, and small industrial applications at a reasonable price in environmentally acceptable manner. Progress during this period accelerated rapidly. The site for the installation of the PAFBC was completed. All of the system components, including the fabrication of the furnace, were also completed. Additional component testing and inspection was also completed. By the end of this period the AFBC was completely assembled and installed at the site adjacent to the MTCI facility and shakedown tests were initiated. 20 figs., 2 tabs.

Summary of the planning, management, and evaluation process for the Geothermal Program Review VI conference
The purpose of this document is to present an overview of the planning, facilitation, and evaluation process used to conduct the Geothermal Program Review VI (PR VI) conference. This document was also prepared to highlight lessons learned from PR VI and, by utilizing the evaluation summaries and recommendations, be used as a planning tool for PR VII. The conference, entitled Beyond Goals and Objectives,'' was sponsored by the US Department of Energy's (DOE) Geothermal Technology Division (GTD), PR VI was held in San Francisco, California on April 19--21, 1988 and was attended by 127 participants. PR VI was held in conjunction with the National Geothermal Association's (NGA) Industry Round Table. This document presents a brief summary of the activities, responsibilities, and resources for implementing the PR VI meeting and provides recommendations, checklists, and a proposed schedule for assisting in planning PR VII.

Advanced fusion MHD power conversion using the CFAR (compact fusion advanced Rankine) cycle concept
The CFAR (compact fusion advanced Rankine) cycle concept for a tokamak reactor involves the use of a high-temperature Rankine cycle in combination with microwave superheaters and nonequilibrium MHD disk generators to obtain a compact, low-capital-cost power conversion system which fits almost entirely within the reactor vault. The significant savings in the balance-of-plant costs are expected to result in much lower costs of electricity than previous concepts. This paper describes the unique features of the CFAR cycle and a high- temperature blanket designed to take advantage of it as well as the predicted performance of the MHD disk generators using mercury seeded with cesium. 40 refs., 8 figs., 3 tabs.

(Pulsed atmospheric fluidized bed combustion (PAFBC))
This first Quarterly Technical Progress Report presents the results of work accomplished during the period April 19 through July 24,1988. The overall objective of the program is the development of a pulsed atmospheric fluidized-bed combustion (PAFBC) technology to burn coal and to provide heat and steam to commercial, institutional, and small industrial applications at a reasonable price in an environmentally acceptable manner. the program scope consisted of two tasks; the first was to establish preliminary feasibility by the use of theoretical and state-of-the-art information. This task was completed during the first quarter of the contract period and a topical report entitled, Pulsed Atmospheric Fluidized Bed combustion (PAFBC) - Preliminary Feasibility Study'' was prepared as a decision point to proceed'' deliverable in accordance with the terms of the contract. This first quarterly progress report therefore covers the contract activities subsequent to the approval of the feasibility study and the decision to proceed with the Task 2 effort. As the initial quarterly technical progress report, this document includes a subsection on background which will be omitted in subsequent reports. All effort during this period was devoted to the design and analysis of the PAFBC. Design drawings were prepared and fabrication and procurement …

Novel concept development of an internal recirculation catalyst for mild gasification
The objective of this program is to provide an overall evaluation of a novel process concept for mild gasification by completing work in three major tasks: (1) Laboratory-Scale Experiments, (2) Bench-Scale Tests, and (3) Proof-of-Concept Tests and Evaluation (optional). During this quarter, experimental work involving potential recirculating catalysts for coal, initiated in the previous quarter, was continued. The construction and shakedown of an all quartz laboratory-scale isothermal free-fall reactor was completed. Three free-fall experiments were performed in an existing stainless-steel free-fall reactor with untreated and ammonia treated Illinois No. 6 high-voltatile bituminous coal, and the analyzed data are presented herein. A survey of available literature on catalyzed devolatilization of coal, coal pretreatment methods, and related topics was made. Based on the results of this survey, two potential recirculating catalysts, in addition to the already selected zinc chloride, were selected for study: ferrous chloride (FeCl{sub 2}) and ferric chloride (FeCl{sub 3}). Also, based on the survey, two coal pretreatment/chemical comminution methods were selected for study, in addition to methanol treatment: ammonia and n-butylamine pretreatment. A matrix of experiments was formulated to study the three catalysts and three pretreatment methods selected. 2 refs., 2 tabs.

Mathematical modeling and economic analysis of membrane separation of hydrogen from gasifier synthesis gas
Investigators are studying hydrogen purification by membrane technology as a means to make the coal-to-hydrogen route economically attractive. To allow prediction of membrane performance and to facilitate comparisons between membrane and other technologies (cryogenic distillation, pressure swing adsorption), they developed a mathematical model to describe the permeation process inside a membrane module. The results of this model were compared with available experimental data (separation of CO{sub 2}/O{sub 2}/N{sub 2} mixtures). The model was first used to calculate the gas permeabilities from one set of mixed-gas experiments; the resulting permeabilities were then used to predict the results of the other mixed-gas experiments. The agreement between these predictions and the experimental data was good. However, model predictions using gas permeabilities obtained in pure gas experiments did not agree with the mixed gas experimental data. This disagreement is believed to be due to plasticization of the membrane by contact with CO{sub 2}. These results indicate that data obtained from experiments with mixed-gas feeds are necessary to adequately predict membrane performance when CO{sub 2} is present. The performance of different system configurations, including one and two stages of membrane modules, was examined. The different configurations examined were single module (SM), single module with recycle …

Design of a microwave calorimeter for the microwave tokamak experiment
The initial design of a microwave calorimeter for the Microwave Tokamak Experiment is presented. The design is optimized to measure the refraction and absorption of millimeter rf microwaves as they traverse the toroidal plasma of the Alcator C tokamak. Techniques utilized can be adapted for use in measuring high intensity pulsed output from a microwave device in an environment of ultra high vacuum, intense fields of ionizing and non-ionizing radiation and intense magnetic fields. 16 refs.
