✦ Synopsis

Possibly the greater economy of actual steam which it is claimed uniformly results from superheated steam lles in the certainty of dry saturated initial steam, the greater certainty of more complete, re-evaporation during expansion, and the presence of less water on the lateriot walls of the steam cylinder demanding re-evaporation during exhaust than would occur with saturated steam.

Practically, superheating is done with the waste gases of combustion, and therefore cost nothing for fuel. Because what is called saturated steam is not always dLv, we should not jump to the conclusion that under all circumstances it is the best plan to use superheated steam.

It may be the case with superheated steam that part of it (the main body) retains a greater specific volume than saturated steam.

Let us see what this increase of specific volume is in the case of the Hart'is Corliss engine.

We can say, with sufficient accuracy tbr our purpose at seven atmospheres.
