E-Book Overview
This publication treats only such parts of the power plant system as are directly related to piping. The design of boilers and engines has not been touched upon, but their operation has been covered. All auxiliary apparatus in the pipe circuit between the boiler and the engine and in the various piping systems for steam, oil, air, etc., have been treated and their general design discussed.
