The Heat Efficiency of Steam Boilers: Land, Marine, and Locomotive


File Size: 13.20 Mb

Description
In his professional career the Author has had frequent opportunities, during the last twenty-five years, of making Tests on Steam Boilers.

Some time ago he began to tabulate many experiments, and, as the list continually increased, he considered that it might prove useful as a collection of facts, if thrown into the shape of a book. With this object he has added the results of various trials made by others, as well as chapters on combustion and kindred subjects. He has endeavoured to make the book as practical as possible, and useful as a reference for Engineers, and those interested in the economical production of steam. The history of Steam Boilers, which dates back 100 to 150 years, is not touched upon, as it would be foreign to his purpose. Boiler tests, in his opinion, are useless and even misleading, unless the heating value of the fuel, analysis of gases, evaporation of water, and boiler efficiency are given. Many engineers are satisfied with recording only the evaporative results in lbs. of water per lb. of fuel ; but, considering how largely fuels differ in their heating value and percentage of incombustible matter, such tests cannot be regarded as satisfactory or exhaustive. So much heat is given to a boiler in the shape of fuel, the greater part of which is usefully employed in evaporating water, while a certain percentage, large or small, is wasted. Many manufacturers, even in England, will now guarantee a certain boiler efficiency with a given fuel. In other words, with coal of known quality and heating value (without economiser) they will guarantee that, say, 70% of the heat shall be converted into steam of a certain pressure from a certain temperature of feed water, and so many lbs. of water evaporated per square foot . of heating surface per hour.
