Now it required a certain number of heat units to
produce this steam which after doing its work gives back all its heat
again to the feed water and it would be a very interesting problem for
some of the young engineers, as well as the old ones, to determine just
what loss if any is sustained in this manner of supplying a boiler. If
you are thinking of trying an independent pump, don't be afraid of this
one. I take particular pride in recommending anything that I have tried
myself, and know to be as recommended.
And a boiler feeder of this kind has all the advantage of the injector,
as it will supply the boiler without running the engine, and it has the
advantage over the injector, in not being so delicate, and will work
water that can not be handled by the best of injectors.
We have very frequently had this question put to us: "Ought I to grease
my gearing?" If I said "yes," I had an argument on my hands at once. If
I said "no," some one would disagree just as quickly, and how shall I
answer it to the satisfaction of most engineers of a traction engine?
I always say what I have to say and stay by it until I am convinced of
the error.
