Is discovery which will reduce THE cost OF
stean-powcr more than sixty per cent! has
recently been made, and put into practical
operation Mt the Atlantic Works i'll this city
by Mr.. Joel a. III. Ellis and his associates.
1t consists of anovc process by which the
great amount of heat that escapes into the air
in the waste or exhaust steam from engines
i utilized Ivy conductngit through tine tubes
Of bnilcr filed with the biSu!phde Of car
bon. "a fluid which boils 10 degrees Fab
renheit, and at the temperature OF exhaust
steam. gives pressure of 90 pounds to the
inch in the boiler" the yapor formed in
this boiler is used to drive an engine, instead
of steam. aid after being used is condensed
ny cooling, pumped into The boiler uGaD,
and used continuously without loss.
Carefully made experiments prove that by
means of this process the saTe fuel now re-
pured to produce one hundred horse power
with the best engines In Use will produce
two hundred and fifty horse power, showing
Il gain of one hundred and fifty per cent. III
the amount Of powcy obtained by the con-
sumption of fuel.
For the purpose of making Il careful test
Of the value Of this process, two new engines
of the same size and construction were put
up at the Atlantic Works; one of them run
Ivy steam in the usual manner. while the heat
that escaped in the exhaust from this engine
was used To heat boiler and drive the Sc
cord engine. 4 careful measurement Of the
power produced by each of the engines made
by +. W. Bacon, Esq, the oldest and most
| experienced engineer in the city, showed
| that while the first engine. worked by steam
| in the usual way. produced % horsepower,
the second engine, worked entirely by the
| waste heat escaping in the exhaust from the
| first. produced 9i2 horsepower, the two to-
| yethcr producing 10 horsepower with the
same li.cl required 10 drive the steam engine
alone.
Tie amount Of coal required to run 4

Vt the best class in Use III the present time is
about 1000 pounds per day or 600 tons Il
year: bv lhcalls OF this discovery the SAINT
engine can be run with $50 pounds Of Goa
| per Gay. or 40 tons Il Year, thus saving G6t
tons of coal Il year for each hundred horse
power produced. At $50 per ton for coal
! the amount saved IN Il year for each hundred
| horsepower is 5000.
| For steam vessels the advantages Of this
process are still greater than for stationary
engines. as Il large amount Of room in the
