Regenerative process for desulfurization of high temperature combustion and fuel gases. Quarterly progress report No. 11, October 1-December 31, 1978

Description: In the continuing search for more reactive calcium silicates, Portland cement, as an ingredient of concrete, has been identified to have favorable properties for sulfur absorption and regeneration. Various Portland cements have been studied for their reactivities for sulfation. Most of Portland cements showed equal or higher sorption reactivities than lime. Portland Type III had unusually high activity for a calcium-based sorbent. Furthermore, pellets could be formed from Portland Type III whic… more

Comparative Cost Estimates of Five Coal Utilization Processes

Description: Detailed capital and operating cost estimates were prepared for the generation of electric power in a new, net 500 MW (e), coal-burning facility by five alternative processes: conventional boiler with no control of SO/sub 2/ emissions, atmospheric fluidized bed steam generator (AFB), conventional boiler equipped with a limestone FGD system, conventional boiler equipped with magnesia FGD system, and coal beneficiation followed by a conventional boiler quipped with limestone FGD for part of the f… more

Desulfurization of coal model compounds and coal liquids.

Description: Most US coals contain sulfur concentrations that prevent their being burned without some form of sulfur removal. Current coal-cleaning technology can only remove the fairly reactive pyritic (inorganic) and aliphatic (organic) sulfur. A process which removes the more refractory hetero-aromatic sulfur could substantially increase the amount of coal reserves amenable to chemical cleaning. Sodium metal dispersions convert refractor model compounds into lighter desulfurized products and non-volatile… more

Assessment of environmental control technologies for Koppers-Totzek, Winkler, and Texaco coal gasification systems

Description: The US Department of Energy, Division of Environmental Control Technology, supports the Assistant Secretary for Environment in discharging responsibilities for environmental control aspects of technology in use and development. The coal gasification technologies employed by Winkler, Koppers-Totzek (K-T) and Texaco are described. Evaluation of the status of these technologies for control of major environmental pollutants indicates that a minimum risk to the environment is involved. The complete … more

Additional research on advanced R and D in Japan

Description: The August 1979 status of research and development programs in Japan on high temperature (inlet temperatures to 3000/sup 0/F) gas turbines, on the cleanup of exhaust gases from gas turbines and from coal combustion for steam generation, on fluidized bed combustion, and on fuel cells are summarized. This information was obtained from reports by and interviews of officials in Japanese industrial organizations and research institutes which are conducting the studies. The results show that economic… more

Assessment of the radiological impact of coal utilization. I. Preliminary studies on Western coal. [Western USA; radionuclide impurities]

Description: It was the purpose of this project to broadly survey pathways of radionuclides in the coal fuel cycle, identifying critical questions and providing direction for subsequent, definitive studies of radionuclides in coal and the technological enhancement of concentrations of naturally occurring radionuclides through use of this coal. Western coal was selected for study because of its prominence in the National Energy Plan. Specific objectives were to: investigate the fate of radionuclides in the c… more

Air quality measurements in the coal-fired power plant environment of Colstrip, Montana

Description: A network of up to six air monitoring and sampling stations were operated 4 to 23 km downwind of the 700 MW coal-fired power plants at Colstrip, Montana. Continuous monitoring identified background SO/sub 2/ levels in the surrounding air at approximately 1 ppB (2.3 ..mu..g/m/sup 3/). Average air concentrations measured in 1978 throughout the network increased to about 2 ppB (4.6 ..mu..g/m/sup 3/) as a result of power plant operations. Meteorological and aerosol correlations with SO/sub 2/ conce… more

Particulate removal at high temperature and pressure by self-agglomeration in a cyclone. Final technical report, September 1, 1977-December 31, 1979

Description: An analytical and experimental study on a high temperature agglomerating cyclone was carried out to determine the cyclone collection efficiency as a function of dust loading and its operating parameters. Experimental data are presented and indicate that the high temperature cyclone collection efficiency based on the ash mass collected in the hopper varies from 89 to 94%. Microscopic examination of collected particles on the filter paper at cyclone exit shows that the collected particles are mos… more

Laboratory Studies of Trace Element Transformations During Coal Combustion

Description: Small-scale coal combustion experiments under well controlled conditions have been used to study the transformation of mineral constituents during combustion. Vaporization rates of various elements from well characterized coal samples have been measured over wide ranges of temperature and gas composition. The implication of these data for modelling the fate of mineral matter is discussed.

Hazards from radioactive waste in perspective

Description: This paper compares the hazards from wastes from a 1000-MW(e) nuclear power plant to these from wastes from a 1000-MW(e) coal fueled power plant. The latter hazard is much greater than the former. The toxicity and carcinogenity of the chemicals prodcued in coal burning is emphasized. Comparisions are also made with other toxic chemicals and with natural radioactivity. (DLC)

Prototype particulate stack sampler with single-cut nozzle and microcomputer calculating/display system

Description: A prototype particulate stack sampler (PPSS) has been developed to improve on the existing EPA Method 5 sampling apparatus. Its primary features are (1) higher sampling rate (56 1/min); (2) display (on demand) of all required variables and calculated values by a microcomputer-based calculating and display system; (3) continuous stack gas moisture determination; (4) a virtual impactor nozzle with 3 ..mu..m mass median diameter cutpoint which collects fine and coarse particle fractions on separat… more
