Quarterly technical progress report, October 1-December 30, 1983

Description: Several new initiatives were begun in coal preparation, including a project to develop a liquid CO/sub 2/ coalescence process that will produce a superclean coal containing less than 1% ash. Another new project in this area is focusing on chemical coal cleaning for the removal of harmful trace elements, such as arsenic, lead, and zinc. Milestones were reached in both of our major electron beam flue gas cleanup projects. In the area of coal-water mixtures, our major industrial contracts are now … more

Pulverized coal firing of aluminum melting furnaces. Final report. [Sulfide capacity of various slags in given temperature range]

Description: Significant progress has been achieved in the development of a desulfurizing coal combustion process by the Aluminum Company of America (Alcoa) in a research program funded by the United States Department of Energy. Conceptually, high sulfur coal is burned with additives in a staged cyclone combustor, such that sufficient sulfur to obviate products of combustion (POC) scrubbing is retained in the slag by-product. Bench scale studies conducted during the program have shown that 70% of the sulfur… more

Quarterly technical progress report for the period ending June 30, 1984

Description: The Magnetohydrodynamics Program (Component Development and Integration Facility) in Butte, Montana, continued its site preparation for the TRW first-stage combustor installation. In the area of flue gas cleanup, our in-house research program is continuing its investigation into the causes of sorbent attrition in PETC's fluidized-bed copper oxide process for simultaneous SO/sub 2//NO/sub x/ removal. Interwoven with these tests is a series of spray dryer/electrostatic precipitator tests that are… more

Modelling and assessment of advanced processes for integrated environmental control of coal-fired power plants. Technical progress report

Description: The key objective of this research is the development of a computer based model for the assessment of integrated environmental control (IEC) systems for conventional and advanced coal fired power plant designs. Efforts during the period April 1-June 30, 1984 focused on, (1) testing of a preliminary integrated model linking pre-combustion and post-combustion control options for conventional plants; (2) documentation of the analytical models of existing control technology options; (3) development… more

Aerosol Particle Charger and an SO/sub 2/ Reactor Using Energetic Electrons

Description: Two properties of energetic electrons in gas, their high specific ionization and their production of radicals and other chemically active specie, have promising applications to the cleanup of flue gas from coal combustion. The copious ionization has been used in a test particle charger to electrically charge 1 and 3 ..mu..m particles for subsequent removal by electrostatic precipitation. Particle charge greater than 5 times the theoretical ionic charging value for 1 ..mu..m particles have been … more

Use of energetic electrons in a particle precharger and in a sulfur dioxide reactor

Description: Electrons energized by corona discharge to produce the necessary ionization for particle charging have been used in electrostatic precipitators for decades. This paper reports the use of an electron beam to release and energize electrons which produce copious charging currents in a bench precharger. Results have been obtained for various values of electron beam energy, beam current, electric field strength, current density, and exposure time in measurements of charging efficiency for large cond… more

On-site field tests for study of low-rank western coal fly ash. Technical summary report, field test No. 3. Big Brown Station electrostatic precipitator

Description: This report describes the results of field and laboratory studies of combined NH/sub 3/ and SO/sub 3/ conditioning at the Big Brown Station of Texas Utilities Generating Company. This unusual combination of conditioning agents is used routinely at the Big Brown Station in order to improve the performance of the cold-side electrostatic precipitators. The primary objectives of this field study were to evaluate the performance of one of the Big Brown precipitators, and to obtain data on the concen… more
