Sayfa 1463 - The charge weighed 9,500 pounds, and after burning 46 hours yielded 4,828 pounds of coke and 572 pounds of breeze and ash. The coke was brittle, with cracks lengthwise and crosswise through it. It was also high in...
Sayfa 1447 - Arkansas, and the slack produced in mining these coals, can be briquetted on a commercial basis. (2) In a number of instances the briquetted coal makes a better fuel and will stand transportation better than the original coal. (3) It is possible to briquette anthracite culm with pitch without the addition of any bituminous coal, and the briquettes will stand up in the fire without crumbling and burn like a lump of anthracite coal. (4) Coke breeze can be briquetted, making a fuel that in burning is...
Sayfa 1463 - Iowa No. 4- — Lump coal from mine No. 3, Centerville Block Coal Company, Centerville, Iowa. The coke produced in this test was of the same general character as that obtained from Iowa No. 3, except that it was not quite so high in either sulphur or ash. The charge consisted of 8,000 pounds of washed (p.
Sayfa 1463 - Iowa No. 5. — Run-of-mine coal from mine No. 1, Inland Fuel Company, Chariton, Iowa. A charge consisting of nearly 5 tons of this coal was washed for a coking test, but the coal did not coke, although the washing was fairly successful in reducing the impurities, as shown by the following analyses: Analyses showing effect of washing Iowa No. 5 coal.
Sayfa 1354 - Lump and run-of-mine coal from Stuart *M. Buck, Mora, W. Va. This test was made on 11,000 pounds of unwashed coal. It was burned for 68 hours and yielded 7,858 pounds, or 71.4 per cent, of good, hard, heavy coke, slightly off color, and 429 pounds of ash and breeze.
Sayfa 1351 - COKING TESTS. West Virginia No. 6. (Mine 188 on Map II). "Coking tests Nos. 27, 30, and 33. — Run-of-mine coal from the New River Smokeless Coal Company, Rush Run, W. Va. "Three tests were made on this coal, which was unwashed. The first charge, consisting of 13,000 pounds was burned for 90 hours, and yielded 8,303 pounds, or 63.9 per cent..
Sayfa 1025 - Colorado No. 1 is a black lignite which clinkered badly in the producer, in spite of frequent poking, but the clinkers were not large and could be broken from the top of the producer. The gas was of a good, uniform quality, and there is no doubt that the fuel can be used to advantage in producers. It yielded a large amount of yellow
Sayfa 1355 - W. Va. Two tests were made on this coal, the first being unwashed, the second washed. The unwashed charge weighed 10,000 pounds, and was burned 40 hours. It yielded 6,084 pounds, or 60.8 per cent, of coke, and 314 pounds of breeze and ash. The coke was heavy and grayish in color. It was of good quality, though slightly brittle. The coke from the washed coal (p.
Sayfa 1316 - In considering the possible increase in efficiency of the boiler tests with a compound engine substituted for the simple engine used, the fact should not be overlooked that a corresponding increase in the efficiency of the gas-producer tests may be brought about under the most favorable conditions. The gas engine is passing through a transitional period. In the larger sizes the vertical single-acting engine is being replaced by the horizontal double-acting. Other changes and improvements are constantly...
Sayfa 1443 - ... itself is a very good coking coal. The briquettes, when exposed to the weather, were affected but little and did not disintegrate appreciably. In burning they held together until entirely consumed. This coal was also tested with the Hoffman patent binder, and the resultant eggettes were also of very good quality, being hard, glossy, and clean; but in burning they caked more than those with 5 per cent of pitch.
