Seite 1361 - This coal was tested washed and unwashed. The unwashed charge contained 12,000 pounds. It was burned for 65 hours and yielded 8,907 pounds, or 74.2 per cent of coke, and 428 pounds of breeze and ash. The charge of washed coaj (p. 1472) weighed 9,000 pounds. It was coked for 42 hours and yielded 6,367 pounds, or 70.7 per cent, of coke, and 374 pounds of breeze and ash. The coke obtained was of good, color, but was somewhat impaired by cross fractures. No improvement was noticed as a result of washing....
Seite 1328 - 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...

Seite 1455 - ... 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.

Seite 1348 - All of the Iowa coals tested are too high in sulphur to produce blast-furnace coke, and as the sulphur occurs largely as gypsum it can not be removed by washing. The ash is also high in relation to the fixed carbon.
Seite 1358 - ... Run-of-mine coal from Pitcairn mine of the Pitcairn Coal Company, Clarksburg, W. Va. Two tests were made of this coal, unwashed and washed. The first charge was 9,000 pounds of unwashed coal, producing 5,235 pounds of gray coke, somewhat brittle and high in sulphur and ash. The washed coal (p.
