Advanced combustion system for industrial boilers. Quarterly technical progress report, August 1987--October 1987 (open access)

Advanced combustion system for industrial boilers. Quarterly technical progress report, August 1987--October 1987

The purpose of this project is to develop an advanced coal-combustion system for industrial boilers. With the new combustion system, coal could be used to replace oil and possibly gas as fuel for many industrial boilers. The advanced combustion system is comprised of several parts: (1) A new burner-design concept for coal fuels, developed from the familiar gas turbine combustor-can designs that have proven efficient, reliable, durable, and safe for the combustion of liquid fuel oils. (2) A coal storage and dense-phase feed system for injecting clean, ultrafine pulverized coal into the burner at a low velocity. (3) An automatic control system based on feedback from low-cost automotive combustion-quality transducers. A cold flow model of an initial phase of the new burner design and the associated laser flow-visualization techniques were developed during this quarter. A series of modifications of the initial cold flow model will be tested to establish details of design for the new burner. Also a 200 hp firetube boiler has been installed and tested using number 2 oil as a fuel. This boiler will be used for future combustion testing with the new burner and ultrafine pulverized coal. Additionally an ultrafine-coal injector has been designed which will …

Advanced development of a pressurized ash agglomerating fluidized-bed coal gasification system: Topical report, Process analysis, FY 1983 (open access)

Advanced development of a pressurized ash agglomerating fluidized-bed coal gasification system: Topical report, Process analysis, FY 1983

KRW Energy Systems, Inc., is engaged in the continuing development of a pressurized, fluidized-bed gasification process at its Waltz Mill Site in Madison, Pennsylvania. The overall objective of the program is to demonstrate the viability of the KRW process for the environmentally-acceptable production of low- and medium-Btu fuel gas from a variety of fossilized carbonaceous feedstocks and industrial fuels. This report presents process analysis of the 24 ton-per-day Process Development Unit (PDU) operations and is a continuation of the process analysis work performed in 1980 and 1981. Included is work performed on PDU process data; gasification; char-ash separation; ash agglomeration; fines carryover, recycle, and consumption; deposit formation; materials; and environmental, health, and safety issues. 63 figs., 43 tabs.

Advances in technology for the construction of deep-underground facilities (open access)

Advances in technology for the construction of deep-underground facilities

The workshop was organized in order to address technological issues important to decisions regarding the feasibility of strategic options. The objectives of the workshop were to establish the current technological capabilities for deep-underground construction, to project those capabilities through the compressed schedule proposed for construction, and to identify promising directions for timely allocation of existing research and development resources. The earth has been used as a means of protection and safekeeping for many centuries. Recently, the thickness of the earth cover required for this purpose has been extended to the 2,000- to 3,000-ft range in structures contemplated for nuclear-waste disposal, energy storage, and strategic systems. For defensive missile basing, it is now perceived that the magnitude of the threat has increased through better delivery systems, larger payloads, and variable tactics of attack. Thus, depths of 3,000 to 8,000 ft are being considered seriously for such facilities. Moreover, it appears desirable that the facilities be operational (if not totally complete) for defensive purposes within a five-year construction schedule. Deep excavations such as mines are similar in many respects to nearsurface tunnels and caverns for transit, rail, sewer, water, hydroelectric, and highway projects. But the differences that do exist are significant. Major …

Antenna organization in green photosynthetic bacteria. Progress report, July 1, 1985--June 30, 1987 (open access)

Antenna organization in green photosynthetic bacteria. Progress report, July 1, 1985--June 30, 1987

This project is concerned with the structure and function of the unique antenna system found in the green photosynthetic bacteria. The antenna system in these organisms is contained within a vesicle known as a chlorosome, which is attached to the cytoplasmic side of the cell membrane. Additional antenna pigments and reaction centers are contained in integral membrane proteins. Energy absorbed by the bacteriochlorophyll c (BChl c) pigments in the chlorosome is transferred via a ``baseplate`` array of BChl a antenna pigments into the membrane and to the reaction center. A schematic model of chlorosome structure is shown. This project is aimed at increasing our understanding of the organization of the pigments in the chlorosome and how the antenna system functions.

Antenna organization in green photosynthetic bacteria. Progress report, March 1986--February 1987

This project is concerned with the structure and function of the unique antenna system found in the green photosynthetic bacteria. The antenna system in these organisms is contained within a vesicle known as a chlorosome, which is attached to the cytoplasmic side of the cell membrane. Additional antenna pigments and reaction centers are contained in integral membrane proteins. Energy absorbed by the bacteriochlorophyll c (BChl c) pigments in the chlorosome is transferred via a ``baseplate`` array of BChl a antenna pigments into the membrane and to the reaction center. This system is similar in some respects to the phycobilisome antenna system found in cyanobacteria and some types of algae, in that a membrane-associated structure absorbs light and transfers it to the membrane where conversion to chemical energy takes place. However, the overall structure, the type of pigments utilized and the nature of the proteins in these two types of membrane-associated antenna bodies are entirely different, and they clearly represent two independent evolutionary solutions to the problem of light collection and excitation transfer.
