A NEW STEAM CONDENSER.

A correspondent of the New York Courier and
btquiror writes to that jottmal:

" As this is eensitatically the age of steam power, and
of progress in its use, whatever relates to this subject
must possess especial interest. The object of this commu-
nication is, to gate through the columns of your salaeble
paper, that 'here is now in full and successful operation, at
the North Point Foundry and Machine-shop in Jersey City,
a "condenser," invented by Mr. J. Miller, lately of New
Orleans, which is calculated to exercise a moat powerful in-
flumes on the employment of steam power. This condenser
is so constructed as to convert the steam into water, return it
to boilers undiminished, and thus, when they are once filled
with pure water, they will continue to operate fora week or
more without adding one additional drop of water to that
already in the boiler. A steamer could readily carry, in
• few hogsheads, an ample supply of fresh water to last
across the Atlantic Osman, or, if salt water wets used, it
would be immediately converted into fresh by the conden-
sation of the strum, and very trifling precipitation of salt
or other impurity would take place, while under the
existing system the broilers are speedily choked up or burnt
out, and all the pipes are in danger of filling and becoming
foul, and, to this cause alone, nine-tenths of the steamboat
explosions and other accidents are attributable. It has
been ascertained, from actual experiment, that a steam-
engine, with this condenser attached, will produce equal
power, at • saving of more than one-third of the fuel. By
this attachment it turns the high pressure engine into a
low pressure, and reducll the great unwieldly ter pump now
in use to one-tenth its size. This ia a great security against
danger or derangement of the machinery. Any wet of
engine can be used for the attachment of this condenser.
Another essential advantage is, that the engine and
machinery are reduced in bulk at the top, and the main
weight can he placed nearer the bottom of the ship, thus
increasing the fiteedine4a of its motion, and its safety in
rough weather. I understand that one of these condensers
is also in complete operation at Pittsburg, and has attracted
the favourable noticeof many of the most experienced steam-
boat builders and engineers. Proposals have been made
to put it on several of the best boats running on the Ohio
and Mississippi rivers, and will, no doubt, be WOO carried
' into effect. Arrangements are also in progress to put it on
several of the ocean steamers in this city. It is regarded by
the best judges as one of the most valuable improvements
of the day, sodas esstain to save the lives of thousands who
travel on steam-beats and steam-vessels. I visited this
engine end condenser at Jersey city, yesterday, in corn.
pony with several intelligent and experienced gentlemen,
nod witnessed its operation. Nothing could be more
simple and beautiful. I was assured by the tenders and
workmen that it had been in constant use for nearly nine
months, and that it had never failed to perform satisfacto-
rily, and gave evidence that it was • thorough and trium- '
pliant attainment of the great drai.,,ralsons, of clearing the
water of all impurities, and thus protecting the boilers and
engines from the imminent peril of explosions, collapses,
and accidents, such as have so oltened tilled oar land with
mourning."
