Book excerpt: For the past two and one-half years Atlantic Research has been conducting a research program which involved development and combustion of slurries of coal in oil and in water. In Phase II good candidate slurries chosen from Phase I were burned in an experimental furnace and their combustion performance evaluated. Two slurry fuels were chosen for the combustion study. One consisted of a 50/40/10 (weight) coal/oil/water mixture, and the other was a 65/35 coal/water slurry stabilized with modified corn starch. The emphasis was placed on the coal/water slurry. Firings were conducted in a one MMBTUH experimental furnace constructed and instrumented for the purpose. A specially designed swirl burner/atomizer was developed for use with the coal/water slurry. Both slurries were burned successfully. Numerous firings were performed of up to one-half duration each. In the case of the coal/water slurry a small amount of gas assist was usually used, although this was eliminated in several shorter duration tests. Thermochemical calculations for coal/water slurries are presented. The presence of water in the slurry represents a relatively small energy penalty. A slurry made from a good coal will have a calorific value in the range of 10,000 Btu/lb. The heat required to vaporize the water of a 70/30 mixture is only about 300 Btu/lb slurry, or about 3 percent. Analysis of the results led to the conclusion that significant improvement in the burning maybe achievable, possibly to the point where combustion rates would be comparable to those of heavy oil. Because of the availability of coal, its cost advantage relative to oil, and especially because of the ease of handling of a liquid fuel, coal/water slurry appears to have considerable potential as a future fuel.

This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Slurry fuels comprised of either bituminous, subbituminous, or lignite coal, and either aqeuous media or emulsions of No. 6 oil in water as the carrier were developed and evaluated at solids loadings up to 70% by weight. Emphasis was placed on aqueous slurries of bituminous coal. These slurries were developed for use in place of No. 6 oil in oil-fired burners. High solids loadings were attained by use of bimodal particle size distributions, which are blends of coarse-grind coal (approx. 50 to 85% -50 mesh) and fine-grind coal (generally 90% -200 mesh). The effect of the blends on slurry viscosity was determined to find the blends that minimize viscosity. The effect of mill conditions on particle size distribution was determined for each coal, using a hammermill pulverizer. A large number of water-soluble resins were evaluated for effect on slurry stability and viscosity. The best of these was found to be hydroxypropylated corn starch. Slurries based on the use of 3% solutions of the starch in water were prepared with up to 70% by weight bituminous coal and up to 65% subbituminous coal. The slurries are pourable pseudo-plastic fluids having room-temperature viscosities in the range of 550 to 1100 cp at a shear rate of 3000 sec−1, depending on the type of coal, solids loading, and particle size distribution. None of the slurries exhibited hard pack settling, even after room-temperature storage up to 74 days. Oil-in-water emulsions made with polyethylene glycol (23) lauryl ether as an emulsifier were found to be stable with respect to phase separation when stored at 160°F. Slurries made with these emulsions do not exhibit hard pack settling after one week storage at 160°F.

Book Synopsis Coal-Water Slurry Fuels: An Overview by : Charles E. Minter
Download or read book Coal-Water Slurry Fuels: An Overview written by Charles E. Minter and published by . This book was released on 1983 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coal-water slurry fuel is a fuel that is domestic, in large supply, can be handled like a liquid, burns like coal, costs like coal, and has the potential as a near term alternative to No. 6 fuel oil. Unlike the coal gasification and liquefication processes, the capital investment required is modest. While those synthetic fuel processes cost in the order of $4 billion for a 50,000 barrel per day manufacturing facility, a coal-water plant of that size is estimated at abut $80 million (one fiftieth). While the cost of synthetic fuels has been projected at about double that of oil, the costs for coal-water are estimated at 30% to 40% less than oil. Put another way, assuming a 4% energy loss in the coal-water slurry, the resulting fuel cost of the CWM is approximately $3/million BTU. This can be compared to oil at $29/barrel or approximately $5/million BTU. The successful introduction of coal slurry technology into the marketplace as a replacement for oil has very significant potential. The hand-in-hand development of advanced coal cleaning technologies could allow the U.S. to make an economical and rapid transition away from our least abundant resource-oil-to our most abundant resource-coal. Coal-based slurries hold the promise of truly being the fuel of the 80's and beyond.
