SMOKE-BURNING FURNACES.

To the Ed,ts' Of The N. Y. Tvibsns.
SIR: The idea has been often entertained that ifa
fire could be confined, and have no escape. vast
saving of heat would be thereby effected. The draft
up the pipe chimney, carries off, as variously es-
tmated from one thud to two.thirds Of the value
OF fuel included in the escape of hot air aud uncon
suned gas. In long horizontal arrangements of fire.
such as tiers of sakettles, fifteen twenty kettles
deep, the heat is used to better advantage than
in locomotive boilers, where the flames after fierce
rush through the fues, vanish up the smoke-stack
strewing the route with burning cinders. The
longer the boiler, within certain bounds, the more
hea. il derives from a given fire. The first four
kettles in salt.block occupy about the sans space
horzt ptaIy as the boiler of locomotive. Tue
chimney Of O locomotive rises at point which TO an
old salt. Her would inoicae waste OF two thnds OF
the heat because in his business ii is found advisable
TO ado on kettles 10 ths number of ~ or 80. The
LAST kettles do not eveporae salt water a. fast as
tht re pear the fuel but they do paying lsiness.
Now to stop up the chimney altogether, blow tue
smoke and hotair back into the fire with fan- wer
thus iorniIga circuit in which there should be no

minds as a very desirable accomplishment. Expert

land, but "a yet the results are not Tangible Hereto
fore the forts have ended in the destruction of the
fire. and the experimenters have usually concluded
that tight fire was thing of the same character as
the philophers stone, or perpetual motion 49,,

We divide the ues of the boiler into two sets upper

An imperfect application of our principles may be
