THE ECONOMICAL EMPLOYMENT OF AUXILIARY EXHAUST STEAM
By Lieutenant E. E. Wilson, U. S. Navy
One of the important engineering problems of the day is the attainment of economy by the recovery of waste products through their employment in useful work. In this class comes the recovery of waste heat in the auxiliary exhaust steam—a process which has been well developed in shore practice but more or less neglected by marine engineers. It is the object here to describe one method of recovering this heat which has been entirely successful, with the idea that any features of this particular problem which may be adapted to other installations may be made available.
The fundamental principles involved are as follows:
