Description

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. 1914 edition. Excerpt: ...Appliances--Pages 521-526. Engineers' and Firemen's Handbook--Pages 137-142. Q. 68.--Why is a locomotive using superheated steam more economical than one using saturated steam? A. 68.--Because a locomotive using superheated steam malntains a high cylinder temperature and condensation is thus prevented and much more than the original expansive force of the saturated steam is retained after reaching the cylinders. As condensation represents wasted heat, the superheater engine would necessarily consume less fuel because less water would have to be converted into steam to replace that wasted by condensation with a locomotive using saturated steam. Locomotive Appliances--Pages 517-521. Q. 69.--Should the lubrication of engines using superheated steam receive closer attention than saturated steam engines, and why? A. 69.--Yes, on account of the increased temperature it is necessary to know that the engine is receiving the proper lubrication at all times. Lubricator should be started suflicient time before leaving with the train to know that the valve chambers and cylinders are lubricated. Engineers' and Firemen's Handbo0k--Pages 104, 142. Locomotive Appl.iances--Pages 525-526. Q. 70.--What particular attention should be given the piston rod packing on a superheater engine? A. 70.--Particular attention should be given the swabs and oil cups to know that cups are kept clean and in condition to feed constantly. The engineer should know that the swab is not allowed to become hardened, but kept in a soft, pliable condition and well oiled. Locomotive Appliances--Pages 525-526. Engineers' and Firemen's Handbook--Pages 105, 142. Q. 71.--How should you clean out the sand traps in an air sander where the traps are...show more
