This is a measure which tends as well to making the engine efficient. A recent successful design of triple engine has the steam for the independent air-pump taken from the drip connections of the jackets. Circulation is maintained through the jackets, and no waste occurs. 199. Sundry Connections and Attachments.--The piping necessary for the proper working of an exhaust-steam feedwater heater, the piping for the lubricating appliances, the heater itself, and the lubricators will receive discussion under the subdivision in a later chapter in which they properly fall. The same is true also of the gauges and apparatus of their class which form a part of the engine-room equipment. 200. Summary.--It has been the desire and intention to review the construction and appliances which are to be expected in a power plant so far as relates to the modern engine in the foregoing chapters which have covered the engine subdivision. In the succeeding chapters the boiler and furnace, the setting, and accessories are to be similarly considered. CHAPTER XIX. THE STEAM-BOILER. GENERAL CONSTRUCTION. 201. Introductory.--By reference to pars. 2 and 5 it will be seen that the energy resident in a fuel or source of heat has to be liberated by combustion in a furnace, and that this energy thus liberated is to be stored in a suitable vessel or reservoir from which it may be drawn off as required. The foregoing chapters have treated of the energy communicated to the engine through a' steam-pipe, and the next series of chapters is to treat of the generation of pressure and its storage in the vessel which is called the boiler. Two points of view are therefore of prime...
