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. 1901 edition. Excerpt: ...the air supply requires some heat for its evaporation within the furnace. Eighth--Improper design of the boiler or other apparatus by which the elements of combustion are chilled before they have attained the maximum temperature which the other conditions would permit. Ninth--Unclean heating surfaces and leaky brickwork often cause serious waste of heat. Tenth--Unnecessarily cold feed-water is a source of loss of efficiency. Eleventh--Careless firing may seriously increase any or all of the above losses of efficiency. The working conditions of boilers are but studied by means of boiler tests. These should be conducted according to the Code of Boiler Trials advocated by the American Society of Mechanical Engineers. Copies of the code can be had on application to F. R. Hutton, Secy., 12 West Thirtyfirst street, New York City, or to the writer of this paper. In this code two general methods--the Standard and Alternate--are given. The latter is by far the better and should, in the opinion of the writer, be the standard method. Either method is somewhat laborious to carry out and work up into shape for study and comparison, but the results are worth the while. An intelligent idea of the daily performance of a boiler plant can be gained by a few simple appliances, as follows: First--A reliable water meter placed in the feed pipe of every boiler or in the main feed pipe. Second--A set of platform scales on which all fuel fired shall be weighed as wheeled from the fuel room. Third---A thermometer in the feed pipe of each boiler. Fourth--A pyrometer in the base of the stack or in the up-take of each boiler. Fifth--A record blank for the information furnished by the above appliances. Sixth--A well paid, conscientious head fireman or water tender....
