This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1909 edition. Excerpt: ...said, the height of the water in the boiler, and after that to get down and examine the ash-pan to know whether the dampers are operative, examine the front-end, see that the slide is in the cinder shute and note whether the smoke-box door is bolted up tight in order that no air may get in to destroy the vacuum created by the exhaust steam in the ' front end of the engine; we tell the engineer to also encourage the fireman to do that. We tell the fireman in drifting down the grades with his engine, to close his dampers and regulate his fire at the top of the grade, then close the dampers to prevent the air getting in around the fuel on the grates. If the air gets to the bed of fuel on the grates, of course, it will burn it out in a few miles. We have some drifts of 17 miles and by regulating the fire at the top of the grade and closing the dampers we find we can get down that drift of 17 miles without replenishing the fire or putting any fresh coal on it. We tell the engineer to be careful about the use of the injector and to begin at the top of the grade with water low enough in the boiler so that if the fire should generate a lot of steam, he could apply the injector and hold the pressure in check without being wasteful. We save that much there--keep an even temperature on the boiler and do away with the nuisance of black smoke. We have been telling our firemen something in regard to the proper admixtures of the different elements that enter into combustion in the fire-box. We explain to them that it requires about 32 parts of oxygen to unite with 12 parts of carbon and that if he gets that admixture and. maintains it closely he will generate, for each pound of coal burned, about 14,500 heat units. Fire burning at that ratio will...show more
